    the micro has power to it, and the lite comes on, but it will not start. and the readout is screwed up. keeps saying like "press 2 to start" or some times nothing at all. touch pad doesnt work at all except the two buttons that i mentioned, and they arent the buttons for what they control now. i dont have the product in front of me, so i cant say what the buttons are intended for. "example"(the button mite be the pop corn button, but now it is operating the night light. the other mite be for soup but it now controls the fan)!! thats about the extent of the info that i can explain. just one day started this and that was that. please help. thanks

Hello Biggboo,

It is dificult to say what exactly might be wrong with your microwave, but based on my long distance diagnosis, I'd say its most likely, the control panel circuitry that is screwed up. You will need to get it serviced by a professional, as it is not recommended opening up microwaves if you have no experience. Even when unplugged, there is a capacitor inside which holds upto 2000v charge. You could try to get the control board/electronics replaced. However, in my honest opinion, the cheaper (and probably better) option would be to go in for a new microwave..:)

Hope that helps!

Thank you for using FIXYA!

Cheers!

    here are some more tips:
    Look carefully for any visible signs of damage or spills. The touchpads
    often use pressure sensitive resistive elements which are supposed to be
    sealed. However, any damage or just old age may permit spilled liquid
    to enter and short the sensors. A week or so of drying may cure these
    problems. If there is actual visible damage, it may be necessary to
    replace the touchpad unit, usually only available from the original
    manufacturer. Also, check the snap type connector where the touchpad
    flex-cable plugs into the controller board. Reseating this cable may cur
    a some keys dead problem.

    Some people have reported at least temporary improvement by simple peeling
    the touch pad off of the front panel and flexing it back and forth a few
    times. Presumably, this dislodges some bit of contamination. I am skeptical
    as this could just be a side effect of a bad connection elsewhere.

    With a little bit of effort (or perhaps a lot of effort), the internal
    circuitry of the touchpad can be determined. This may require peeling it
    off of the front panel). Then, use resistors to jumper the proper contacts
    on the flex cable connector to simulate key presses. This should permit
    the functions to be verified before a new touchpad is ordered.

    Caution: unplug the microwave generator from the controller when doing
    this sort of experiment!

    If the problem was the result of a spill into the touchpad, replacement will
    probably be needed.

    However, if you have nothing to lose, and would dump it otherwise, remove the
    touchpad entirely and wash it in clean water in an effort to clear out any
    contamination, then do the same using high purity alcohol to drive out the
    water, and then dry it out thoroughly. This is a long shot but might work.Here are some more tips/reason for no resposive touchpad:
    * Door is not closed - on many ovens, there will be no response to any
    buttons - even setting the clock - unless the door is securely closed.

    * You waited too long - some models (like Sharp) have a timeout. If you
    close the door but don't proceed to activate any functions with a couple
    of minutes, they will require you to open and close the door to reset their
    pathetic brains.

    * Controller is confused - a power surge or random non-reproducible action of
    the universe may have resulted in the controller's program ending up in an
    infinite loop. Pull the plug for a minute or two to reset it.

    * Defective interlock switches - this can result in the controller thinking
    the door is open and ignoring you.

    * Faulty controller or its power supply - a power surge may have damaged
    the electronics. Other than checking for bad connections and obviously
    bad power supply components, diagnosing this will be tough without a
    schematic (and possibly much more).

    * Touchpad or controller board contaminated by overenthusiastic cleaning - if
    you recently power washed the oven (or even if you only use some spray
    cleaner), some may have gotten inside and shorted out the touchpad or
    controller.

    * Defective or damage touchpad - physical abuse is not a recommended technique
    for getting a microwave oven to cooperate. If there is any visible damage
    to the touchpad - the outer film is broken - it will probably need to be
    replaced.

Alright, so basically there is only one thing that can fix your microwave which is a hard reset which means leaving it unplugged for 10 minutes.

If this doesn't work which I expect it probably won't then, your touch pad is fried and is not worth replacing which I have seen happen multiple times

So you will probably end up looking for a new microwave which you can find for under $50

Let me know if you have any further questions, thanks

    If something goes wrong with the touch panel, it is usually not worth replacing like I said before, you are better off buying a new one. I'm sorry but that is the way it is. The panel itself is one of the most expensive parts and never worth replacing.

The internal components that operate the buttons and control the microwave's operations have seemingly worn down. If it is doing what you said, i would think that is is probably time to get a new microwave. (Think about it, you pay about 60 dollars for these things, chances are, they wont last too long. What does?)

Change time on frigidaire microwave no clock button


Hi ssullivan013 - Here are some generics instructions that I found for the model number posted above. Hope the information is helpful.

Suppose you want to enter the correct time of day 12:30 (A.M or P.M.).

1. Touch Clock pad.

2. Enter time 1,2,3,0 and press CLOCK pad again

This is a 12 hour clock. If you attempt to enter an incorrect clock timer, ERROR will appear in the display. Touch the CLEAR/OFF pad and re-enter the time.

I have chefmate microwave and suddenly stopped working. it is showing 2:50 code on the screen only...it was working fine and dont know what happened to it and touch pad is not working..how do i make it...


HELLO.

The code on the screen indicate electric panel fault resulting from the touchpad malfunction.

The touch pad on your microwave oven acts as the brain of the appliance. It not only contains the buttons that you use to enter cooking settings and times, but also controls the function of the entire microwave. If the touch pad malfunctions or breaks completely, the microwave will cease to function. In this instance, the broken touch pad must be removed and a new touch pad must be installed, to restore functionality to the microwave.

1 Unplug the microwave from the wall outlet.
2 Remove the two screws, located on the front or top of the grill at the top of the microwave.
3 Pull the grill off of the microwave.
4 Remove the mounting screw from the top of the control panel.
5 Lift the control panel up and out to loosen. Look behind the control panel to ensure there are no metal tabs securing the control panel in place. If there are metal tabs, gently rotate the control panel to free the tabs.
6 Transfer the wires from the old control panel to the new control panel one at a time to ensure that the wires are properly installed.
7 Install the new control panel into the microwave and secure using the mounting screw that was removed.
8 Replace the grill from the top of the microwave and secure it using the screws that were removed.
9 Plug the microwave back into the wall outlet.
Thanks.

I was washing the Frigidaire microwave today, and now the buttons do not work. I see the time, and the light turns on; I unplugged the microwave and plugged it back again, and the buttons still do not...


Some moisture has probably made its way into the touch pad. You might try heating it a little with a blow dryer on low heat to try and dry up the moisture inside the touch pad or just unplug it for a day or so and see if it will dry up on its own. If it does not start working the touch pad would need to be replaced. Hope that helps.

Microwave Buttons Not Working


all the buttons are connected to 1 control touch pad board.so only two faulty buttons cannot be replaced.whole touch pad of buttons pannel has to be replaced.the cost of the whole pannel will be near to $45 plus service tax.
but as you mentioned its just six months old.contact the dealer as it must be under warranty.if the problem of buttons is considered under warranty you will get the replacement unit or may be the company will get the touch pad replaced for free.
thank you for using fixya.
