Have a GE Spacemaker (Model # JVM1650SH05). Microwave works for a few minutes then displays "F3" code. How can you tell if the Touchpad or Control Board is bad? When it is working for those few minutes,...


F3 on a GE / Hotpoint microwave means you have a shorted membrane keypad.

Part number WB07X10959 this part can run over 100 bucks. If you shop around you could get a good price.

Good Luck

Sharp microwave 8888 is flashing and I cannot remove

see this steps and fix it. God bless you

Reset the clock. Press "Clock" and the correct time, using the number pads. Press "AM/PM" if applicable, and press "Start" or "Clock" to confirm.

  • 2 Press "Timer On/Off" to reset the timer if nothing on the touch pad will operate. Use the number pads to select a new timed amount, if desired, and press "Timer On/Off" to start. Press again to cancel.
  • 3 Press and hold "Clear/Off" for three seconds if the timer will not function or is blinking when you touch the pads. This will release the "Child Lock" feature. Make a new touch pad selection.
  • 4 Disconnect power to the microwave if following Steps 1 through 3 does not resolve the blinking timer. Wait a few minutes, and then restore power to reset the microwave.

  • However if the problem persist the display board
    main control board is faulty

    A small blinking light on the left upper corner of panel after a power outage and I can't do any command. The interior lights don't even come on when opening door. I already reset the breaker

    Unplug the microwave oven for 10 minutes in a attempt to reset the microprocessor ic, press and hold the start button for the same time and release. Now plug everything back in hopes it will restart, if no change! the keypad control board will need to be replaced along with other unknown parts, due to the nature of damage far cheaper to replace.

    I have a Samsung household microwave oven model # SMH8165ST that when plugged in will beep a few times then blink "SE". None of the buttons will work.

    Try calling Samsung....
    Purchased samsung SMH8165ST in Oct 2009. have had the SE code problem for a few month now. Resetting worked at first. Then the light started flasing on & off along with the beeping...would not reset. Out of frustration I called Samsung. I was told they are aware of the problem & would repair in the "epidemic warranty". Repair man just left. It took him about 15 minutes to change out the keypad. No charge!!

    I have a Frigidaire FMV156DBA built-in over-the-counter microwave that started behaving erratically tonight. The light started blinking on and off, accompanied by a repeated beeping. I unplugged the unit...

    Yes have it serviced. Sounds like there is a loose/corroded connection inside and loose connections can cause fires. The intermittent/ramdom operation is indicative of this.

    My aquagard is probling from 2 months the red light is blink when we start aqua iam tired to complaining many times to service centre from where i did emi

    The red light comes on due to a failure to detect the right intensity of light into the controller board. The LDR- light dependentt resistor - is fixed on to the cylinder which has the UV light. Hence the unit is clogged and the light intensity has dropped. You will need to open , clean and reset for the fault to go .Please take the top cover, the glass tubings and the UV lamp out very carefully not to damage.
    If the fault is still persisting then the main board is faulty, sometimes the driver transistors are defective and will not output the voltage to the lamps. Please check this out and I am sure it will work. The service centres normally replace boards even if a transistor is faulty.... so your are right.
    I hope my advice helps.

    GE SpacemakerXL Microwave oven quits after a few seconds

    This disgusting type of repair procedure is called "shotgunning".

    I have always preferred testing and experience to determine what is wrong, as opposed to guessing!

    I assume that they did not charge you for the good parts they mistakenly replaced?

    IF they are a GE-authorized service center, they should have recalled a bulletin from a while back about defective or mismounted magnetrons causing electrical interference that disrupts the controller.

    What your oven needs is a new magnetron and (IMHO) their hands off of it. If the thermostat were bad, the oven would be totally dead.

    You can find GE-authorized servicers by contacting GE Customer Service here.

    Good luck.

    We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
