    microwave oven control board PCBA turnkey assembly Manufacturing
    microwave oven control board PCBA turnkey assembly Manufacturing
    This control board is designed for microwave oven use. It comes with an LED display for convenient operation. Made of rugged construction, this fantastic control board guarantees durability of your microwave ovens.

    t powers up okay, but no hum, and no heat.

    I've checked out YouTube, and didn't learn anything new there.

    If the display is counting down when you press start and stops counting down when you open the microwave door your control panel is at least half way working and part of your door interlock is working.
    does the internal lamp light and fan spin and turntable motor work while the cook time is counting down after you press start-if not you need to pull the board and look for blown tracks on the underside and replace your oven lamp.

    ability of microwave energy to cook food was discovered in 1945 by an engineer in the Raytheon Company. Percy L. Spencer (1894–1979) was inspecting a magnetron at work. (During World War II [1939–45], the magnetron tube had been used in radar systems.) Spencer discovered that a chocolate bar in his pocket had melted even though he had not felt any heat from the magnetron. Next, Spencer exposed some popcorn kernels to the magnetron, and, sure enough, the kernels popped.

    Spencer discovered that, when confined to a metal enclosure, microwaves produced by the magnetron tube excite certain molecules, such as water found in food, causing the food to increase in temperature and eventually get cooked. The first microwave oven, called Radarange, developed by Spencer and the Raytheon Company, was about the size of a refrigerator. It was used in commercial food preparations, and cost about $3,000. In 1955, slightly smaller versions were sold as home appliances, but they were still expensive, and people were not sure they wanted an appliance that they thought emitted "radar waves."

    Either all indicator lights are lit, or no display at all, as though the panel is "dead." (In the case of no display or a "dead" panel, ensure that the low-voltage control transformer is supplying the appropriate voltages. Or if the low-voltage transformer is part of the control board, check for the appropriate input (primary) voltage to the panel before judging it to be defective.)

    SYMPTOM:

    Inspect the area of the ribbon tail that slips into the board connector for cleanliness, for sections where the silver has worn off, or for evidence of scratching or hairline cracks. If cleaning is necessary, do so using an alcohol or freon-based contact cleaner. Do not use silicone-based cleaners or lubricants. Gently rubbing the terminals with a soft pencil eraser will also clean them, but, a word of caution: test the effect of the eraser on a non-essential area first! Erasers have been known to clean the silver right off of the ribbon. In many cases, the problem can be resolved simply by evenly trimming off about 1/16-inch from the tail of the ribbon, leaving fresh new terminals to assure good electrical contact with the circuit board connector.

    A close examination of the front of the membrane touch panel may reveal dents or deep scratches that may be creating a short in certain touch pads. Also, brightening or dimming of the panel-display colons while pressing certain pads is a reasonably good indication that a signal is getting through to the control panel. In that case, try replacing control panel.

    I had a intermittently dim display clock on a JennAir W256B. I recapped the ERC board (Y04100264) with high temp capacitors (found some 135 C caps!) but the problem wasn’t fixed. I tracked it down to a bad solder joint on the transformer/relay board (Y04100260) in the back of the oven. The transformer on this oven provides 21 VAC and 4 VAC to the ERC board. Resistance of the 4 VAC was about 1.1 and the 21 VAC was about 5.0. Flexing the board and the 4 VAC would open circuit. I refluxed all the solder joints on the board and the oven now works properly, with beefier capacitors!

    When I called Samsung, the phone rep said there was no recall on my microwave, and there was nothing she could offer other than to schedule a repair appointment at full price.

    I calmly asked if there was anything at all Samsung could do to ‘work with me,’ since the web was a flurry with so many other customer stories with the same problem.

    The manager took a few minutes to do her own research, and she returned to continue our ‘negotiations.’

    She said my unit wasn’t on their recall list of microwaves.
    (There’s a recall list of other Samsung microwaves in trouble?!)

    But…
    (Let the silence here work in your favor.)

    She could offer me a free one-time repair visit, which included parts and labor.
    YES!!

    Some additional symptoms that indicate a defective key or touch panel are: 1) Only certain pads or groups of pads will respond while others will not. 2) Touching a pad produces a string of characters on the display. 3) One character remains constantly on the display, and disconnecting the ribbon connector from the control board removes it. 4) Some or all pads must be pressed hard or pressed several times to produce a response. 5) The number displayed is different from the one pressed (i.e., press the "5" pad and a "9" appears on the display).

    Lift the control panel and unhook the bot-tom bracket from the slot in the chassis.Rotate the panel so you can access theelectronic control board wiring.7.Disconnect wire connectors P2 throughP4 from the electronic control board.8.Disconnect the red and brown wires fromterminals of relay 4903.9.Remove the green ground wire screw andremove the control pane

    Besides the substitution of a known good panel, the next most certain method of isolating this type of problem is to make continuity checks through each of the touch unit circuits with an ohmmeter. However, without specific data on the matrix configuration of the unit to be tested, this is virtually impossible. Therefore, Appendix I contains many of the common matrix diagrams, listed by make and model number, and instructions on how they are tested.

    Either a continuous beep or buzz; or none at all.

    SYMPTOM:

    The timer buttons remain depressed, thus holding the oven in a continuous cook mode. Litton and some other models use individual pushbuttons that are soldered on to the printed circuit board. These buttons may stick in the depressed position due to inadequate clearance through the cutouts in the timer faceplate. In these cases, the circuit board position may be adjusted to equally center the buttons in their openings, ensuring that the cutouts and buttons are free of grease and residue. In more extreme cases, the size of the hole can be increased by filing the sides of the obstructing cutouts with a small, fine file (the circuit board must be removed first). Then clean any metal filings from the casting and re-assemble the timer, making sure that the timer board is centered so that the buttons operate freely.

    If the lamp lights,the turntable motor and fan works but no supply to the hv tx you need to look at the door interlock micro switches-they should be closed with the door shut and they work with the control board in such a way that your oven cannot be used in cook mode with the door open.
    Failure of the primary or secondary interlock will cause no supply to your hv tx-there is a third interlock called the Monitor Interlock which monitors the status of the other interlocks such that closing either primary or secondary interlock will instantly blow fuses with the microwave oven door open so check these switches with your microwave disconnected from the mains supply.
    Chances are when you find the micro switch responsible a replacement will get things going again as long as theres no other fault with the hv section of the microwave....

    I unpluged the two wires going into the transformer, and hooked up my DMM leads, and I'm getting nothing.

    If the microwave display is not working the main control board is most likely defective and will need to be replaced.

    Fantastic service with fantastic results! My swing gate opener control failed to respond. Power was to the board and no apparent blown fuses. Our local gate service company was sure they could trouble shoot and repair so I scheduled a service call. The technician failed to find the issue but we did notice possible insect infestation with some potential arcing within the circuitry of the back of the board when removed from the control housing. Time to replace the board? I received a call back from the service company that the board was obsolete and I nice big quote for a new control was attached. I spent hours looking for a replacement board with no success. During the search I learned about FixYourBoard.com. I called and pictures of the control board were requested. The techs reviewed and felt they could repair. The board was sent in and back to me within two weeks total. I reinstalled the board and the swing gate has never worked better!! Thanks to all the professionals

    China OEM/ODM electronic pcba services for monititor in Shenzhen China
    The first one is obvious. You need an old microwave. Preferably one that's being thrown out because it's stopped cooking like it should. One from a yard sale or the local thrift store will work. Why use a second hand device you ask? Well first of all it will be much less expensive. Second, it keeps part of it out of a land fill. Lot's of people don't recycle those and it's a crying shame. There are a lot of useful parts in them. All kind of things like microswitches, screws and other hardware, and let's not forget the emitter it's self. Then there's that huge step-up transformer. There's a chance that the emitter or the transformer are damaged in most cases. The switching device is usually still workable. That's just what it is too. A programmable switch.

    The tools you'll need are as follows:

    1. A Soldering iron and solder
    2. Wire cutter/stripper
    3. Various screw drivers (depending on what they put it together with. It varies between makes and models.
    4. A Dremel or some other means of cutting metal and plastic.
    5. A drill or you could just use a drill bit in the Dremel
    6. Safety glasses (You won't be able to do this if you can't see because something got in your eye. It happens, just trust me and use a pair.)
    7. A multimeter (preferably digital because their more accurate.)
    8. A power cord (the heavier, the better.)
    9. Some outlets and boxes (I used panel mount outlets that I got from Home Depot)
    10. A hot glue gun (This is optional depending on how you plan to build it)
    11. Electrical tape

    All I did was plug mine back in, the stupid SE code came back on, and I took my hair dryer, using high heat, waved it back and forth across the keypad panel while sort of massaging the keypad. I also, for good measure, aimed the hairdryer to the underneath side of the keypad. I did it for at least a minute or two, or until my fingers got too hot to massage! Then, like magic, I got a “enter time of day” display on the keypad. I don’t recall if it came up by itself or if I hit the cancel button, but I think it came up by itself. I entered the time following the display instructions, and it started working again!

    Here is my disclaimer – I have had to repeat the process twice so far. The unit works for about 20 minutes, then it asks for the time of day again. I am hoping that after a few times it will simply be ok. I believe the reason our unit has this issue is due to steam from the cooktop below. We have a large garden and I have been doing a lot of canning. So I am hopeful that by continuing to use the hair dryer method, it will eventually dry out and be totally fine.

    I have a NuWave oven thing that is basically like a plug-in hot plate that I will use for anything that produces steam in the future! Too bad they make microwaves that really can’t be used above the range! Duh! When this one finally fails, I will do my homework to find a better made microwave.

    3. Do Your Research
    When I spoke to ‘the manager,’ I felt prepared, because I had done my homework.
    And the fact I was not alone with this particular Samsung failure didn’t hurt.
    Also, I tried to act like the two of us were working together on my problem.
    (It’s a slight attitude tweak, and it can make all the difference…)

    Self-Diagnosis: As digital circuitry becomes more sophisticated, more manufacturers are providing a self-diagnostic test sequence that can be programmed into the control unit. The control panel responds, in most cases, with a code that indicates the likely problem area. For the respective test and related codes for any of the various models that offer this feature, consult the appropriate service manual or contact the manufacturer.

    So I've taken apart an old microwave oven with a touch-sensitive LCD screen. I understand that I could die from playing around with this, so I've disconnected the high-voltage transformer and the magnetron. I'm also not going to remove any of the safety switches like the door switch. My question is, how is the microwave controlled? I'm thinking there is a computer chip somewhere in the circuit, and I'm looking to replace it with an Arduino board plus some extras, like AC relays and such. I'm curious as to how the microwave oven controls its functions, like power level, cooking time, and the beeping. Any advise as to how I could get started interfacing?

    Here’s the inside scoop on what’s happening. The digital display is powered by very specific DC drive voltages. Theses voltages are created by a transformer and stabilized by capacitors, all of which are located on the control board. Most of these capacitors are only rated to a working temperature of 220˚F. Well, it don’t take a brain surgeon, like yours so very frikkin’ truly, to realize that over time the heat will reduce the capacitor’s ability to capacitate thus lowering the drive voltage and dimming the display. Awwite, that’s all the theory we need to know so let’s get into the generic strategery of this repair…

    The specifics will vary with the exact layout and composition of the control board you’re working on but, generally, the flow goes like this:

    1. Kill power to the unit.

    2. Disassemble whatever you need to to get at the control board.

    3. Locate the capacitors on the control board. Typically, there are three but, again, go with what you see. They’ll look something like this:

    If the touch pads on your microwave oven do not respond but the display lights up, the problem may be with the control board. The control board generates a low voltage that is supplied to the membrane switch. When a pad is depressed, the voltage signal is switched back to the control board. The control board receives these input signals from the membrane switch or touch pad and uses these commands to turn on output relays that control the various components of the microwave, such as the turntable motor and the magnetron. If the control board does not generate the low voltage signal, or if it does not sense the input signals from the membrane switch, then no output functions will occur. If you have verified that the membrane switch is fine and the connection to the control board is okay, then the control board may be defective. Replacement will require disconnecting the power and removal of the cabinet and control assembly.

    First things first. Decide what your going to build it out of. If your going to use wood be sure to paint the inside to help seal it from getting moisture build up. Again, This is a safety precaution, Though it's not likely that it will get wet, I take this step just to be sure it doesn't become dangerous. At least not as bad as it could get without doing this. I don't know if you've ever touched a hot wire while in contact with wet wood or not. I have. Luckily it was just an electric fence. It hurt pretty bad but luckily it wasn't harmful. It sure felt worse than it was. That is to say that water and electricity don't mix well whereas human contact is concerned.

    That said PLEASE, DO NOT use this around water or liquids of any kind. That means you don't use it for the bathroom heater GFCI (Ground Fault Circuit Interrupter) outlet or not. It's not safe to use this around sinks or bathtubs so don't do it. If you use this in a wet environment and get hurt, remember I warned you about that. So people PLEASE be careful.

    We replaced the turntable motor as we thought it was shorting out the microwave. This did not fix the microwave. We then unhooked the wire harness from the microwave turntable motor thinking this would help. This did not help, the microwave would shut off on its own every time after 3 seconds. We then took the microwave apart by first unplugging it from power and removing 2 screws from the grill at the very top of the microwave. After removing the top air inlet portion, we removed one screw that holds the control panel on. We removed the control panel by lifting UPWARDS on it. It then popped out and we looked at the control board and display panel. There was no sign of a damaged capacitor on the board or any burn spots whatsoever. The wiring looked fine and everything was plugged in as it should be. The control pad was in perfect condition. We then examined and tested the door switch with a multimeter and it tested good. So we then tried a few things…

    Now that the safety stuff is out of the way let's get on with it shall we? Regardless as to what your using for your materials, your going to have to make holes in it for the outlets. We can do this one of several ways. The first way which is what I did, is to use our Dremel and a cut-off wheel. It makes pretty quick work of metal or the type of board that I used for the front panel. They also work pretty well on plastics. The only concern there is that the plastic tends to melt with the friction which can send chunks flying towards your eyes and face. This would be a really good time to don those safety glasses. Trips to the hospital should be social visits, not necessary emergencies.

    Repairing your microwave might seem like a difficult task, but more than 80% of our customers rate these repairs as “easy” or “really easy.” On average these repairs should take less than 15 minutes to complete. We break microwave repair down by common symptoms, like your touchpad is not responding, your microwave is noisy, your tray will not turn, or your door is stuck. This step-by-step guide teaches you how to troubleshoot. You will learn what parts are at fault, and how to test, fix, or replace them.

    The control panel "kicking out" of a cook cycle prematurely, then possibly "locking up." The oven may have to be unplugged then plugged back in before the panel will accept programming. Possible causes: poor or improper grounding; or, excessive amounts of stray RF leakage, either from the latch side of the door, or from the magnetron within the component compartment. If removing the outer case alleviates the symptom, suspect leakage from the RF gasket or the internal structure of the magnetron.

    SYMPTOM:

    The control panel counts down too quickly or too slowly. Inaccurate timing may also be the result of an oven (of the type that can be converted from 50 to 60 cycles and vice-versa) being set for the wrong voltage or frequency for the area in which it is being used.

    What ever material you use make sure you don't over work your Dremel. You want to put just enough pressure to keep it cutting but not enough that you might break the disk. If you do break one chock it up to a learning experience and be glad it scratched the safety glasses instead of your eye. You could also use a router for this. Another good set of tools would be a drill and a jigsaw. If you use standard household outlets you could even use a hole saw. Whatever your method be sure to mark and cut very carefully. Remember, you can always take more material off. If you cut to much it's gonna look sloppy. That's not to mention that things won't fit quite right. This is why I suggested standard outlets. They can be mounted in wall boxes which makes them a lot safer than most other types of power outlet.

    As a matter of fact you could use the inlet from an old computer power supply to give your project power. It would make it more portable because the cord could then come off. I have no idea why it would need to be that portable as I've never had to take mine anywhere or had a reason to. It's just a thought I had one day while I was moving into a new house and tripping on the cord. See? Safety. Not the best idea if you plan to use it to limit the on-time of a heater or large halogen sun lamp (good timer for a home made tanning station.) Just be careful not to overload the cord or relays. Why yes, this is the reason for the master kill switch. Thank you for asking.

    SYMPTOM:

    Check/Repair: Push the Clear/OFF pad. Shut off power to the oven, disconnect the flat ribbon connector from the electronic oven control board and then restore electrical power. If the code reappears after about 30 seconds, replace the electronic oven control board. If the code doesn’t reappear, replace the key panel.

    The control panel will not start, or fails to count down when started; or, the panel counts down but neglects to activate the cook relay, triac, stirrer or blower motor, or other panel-controlled component. This may also be the result of a misadjusted or defective interlock switch, faulty wiring or related connections, or an open thermal protector or fuse.

    NOTE: The triac or triac module (part of many control units) may be checked in several ways, all of which are outlined in Sections 13-12 through 13.16.
    SYMPTOM:

    She said she could bump my question up to a service manager, and I gladly accepted that option.

    Our ten-day gamecation seemed to fly by. When it was over, we had assembled, painted, based, and fielded two 12-player Blood Bowl teams, built several terrain pieces, and painted up a bunch of Frostgrave treasure tokens and scatter terrain. Last year’s experience was some of the most fun I’d had in recent memory. This year topped that. It was a great way of forcing myself to take a break from work, get a lot of hobby time in, and it was a really wonderful bonding experience with my son. I’m already looking forward to next year.

    If you have a hobby or maker activity that you love, but never feel like you give yourself over to it, if you have the means to do so, DO IT! The past two years have been such great gifts. I encourage you to think about trying a makecation yourself one year. And if it’s something you can do with your kids or your partner or a group of friends, all the better.

    he magnetron tube consists of a filament heater, a metal anode, two magnets, and an antenna. The filament, which functions as the cathode, is enclosed in a ring-shaped metal anode. Then the cathode and the anode are sandwiched between two magnets. These components make up the assembly that will generate the microwaves. A metal strap holds the complete assembly together. Metal cooling fins, which are welded to the anode cylinder, help get rid of the heat produced by the magnetron. A thermal protector is mounted directly on the magnetron to prevent damage to the tube from overheating.

    5 An antenna enclosed in a glass tube is connected to the anode cylinder. Then, the air within the magnetron tube is pumped out to create a vacuum. The antenna is connected to the waveguide, the hollow metal enclosure through which microwaves are transported from the magnetron tube to the cooking cavity. A blower motor is attached to the magnetron, and then a plastic fan is attached to the blower motor to provide cool air to the magnetron to prevent overheating.

    I wish I could give credit to the person who suggested my fix, but I don’t recall where I read it. I looked at many sites on this issue with this pesky microwave oven!

    If the touch pads on your microwave oven do not respond but the display lights up, the problem is most likely with the membrane switch. This component, which is more commonly referred to as the touch pad, is actually a series of soft touch electrical switches. It is usually made up of two layers of a thin Mylar plastic with a conductive material on the inner surfaces. A formed gap between the two surfaces will separate the conductive coatings until pressure is applied by the user, making the two surfaces come in contact. When the two conductive surfaces contact each other, an electrical circuit is completed to provide an input signal to the control board. With repeated use, the conductive coating will eventually wear out and be unable to make a good enough contact to send the signal to the control board. To access the membrane switch you will need to unplug the unit and remove the cabinet. The membrane switch is often attached to the control panel and is usually connected to the electronic control board with a flat ribbon style connector. Check the connection first and if it appears okay, then you can test the membrane switch for continuity with a multi-meter. There should only be a few ohms of resistance for each touch pad when pressed. To perform this test you will require the matrix layout of the membrane switch which should be contained in the electrical schematic.

    Contrary to a popular myth, a microwave oven does not cook from the inside out. If the food is small, the microwaves penetrate it, cooking it all at once. If the food is large, the outside gets cooked by microwaves, while the inside is cooked by the heat transferred from the hot exterior portion of the food.

    At PCBR, we repair your individual appliance control. PCBR will rebuild controls for ranges, stoves, microwave ovens, laundry, dishwashers, and refrigerators. Your control is upgraded using our history of past problems for that particular board, and we fix any potential problems before they occur. Our plant is authorized to rebuild for many manufacturers, including Whirlpool, Maytag, BSH, Kenmore, and others.

    I am obsessed with a most ridiculous hobby. Many hobbies are known for being a time suck and a wallet drain, but few are more of these than tabletop hobby wargaming. I have been playing all manner of boardgame, roleplaying game, and wargame most of my life. My real passion is for tabletop fantasy and sci-fi miniature wargames. This is a very multi-disciplinary hobby in which you plan your armies, assemble and paint your miniatures, build the gaming tables you play on, construct the buildings and terrain that go on the table, plan games and campaigns, and then, after all of that, you can spend hours, weeks, even years playing through a game or series of linked game campaigns.

    PCBR is a contractor company. Warranties are offered to contractors only. Why? For your safety! Appliances are typically 220 volts; some have capacitors that carry a big electrical charge of energy even when disconnected. If you are on this web site and not a contractor, we urge you to use a qualified technician to remove and reinstall appliance controls. In addition, it is sometimes very difficult to determine if the controller is the particular failed component. Other devices like a sensor temperature probe, or touch panel, power supply, or wire connection could show the same symptoms as a faulty controller, and they may be part of the problem.

    • Manufacturers caution users not to put metal utensils or aluminum foil inside the microwave oven. These objects, like the metal walls of the oven, will reflect microwaves. When the powerful microwaves act on the walls and the metal objects, the air between them becomes charged with electricity, thereby causing sparks. These sparks can damage the cooking cavity.

    In 2000 two Massachusetts inventors received a patent for a microwave oven that can be installed in a car's glove compartment. The oven would be powered by the car's battery and the controls would be mounted on the dashboard. The oven comes with a bin that could store things when the oven is not being used. The oven would only work when the bin is not in place.

    A categorized collection of used touch panels (or keypads) is a good idea for testing purposes. Unless they are totally inoperative, do not throw away used touch panels. They take up little room and can be used very effectively. For example, suppose you replace a touch panel because the "2" and "4" pads do not work. Label the defective panel appropriately, and save it. One day, a similar oven comes along, with a different symptom: the "start" pad will not respond. Temporarily replace the latter touch panel (with the unresponsive "start" pad) with the used touch panel having the functional "start" pad, and test the unit. If, with the substitute test touch panel installed, the oven still will not "start", the problem is likely not in the original touch panel. On the other hand, if the test panel "start" pad works, replace the original touch panel. A categorized collection of the touch panels—commercial and domestic—will take much of the gamble out of control panel-touch panel dilemma.
