I fixed by unplugging the microwave with the door open. I plugged it back in and the F6 was gone. I was then able to set the clock and turn the light on/off . When I closed the microwave door, the F6 came back on and the microwave was making a humming noise. I slapped the side of the microwave near the keypad, and the F6 cleared from the readout and the humming stopped. The microwave is working fine now. Don't know why, except maybe slap on the side reset a relay or something.

Microwave will not run a cook cycle. Touchpad functions until door is opened or start button is pressed. When door is opened display goes dark. When door shuts display lights all characters and then says...


BEFORE DOING ANYTHING DISCONNECT OVEN FROM POWER. I do NOT recommend doing repair by yourself, if you NOT are really very familiar with electric repair, or have at least basic training in electric device repair and maintenance.
"When door is opened display goes dark. When door shuts display lights all characters and then says "touch clock"."
Obviously, by opening door, oven gets disconnected form power line.
This is mostly caused by loose connections on wiring socket, and can be anywhere inside. Check security micro switch on door latch. This switch normally disables only running the oven when door is open, for security reasons. In your case, it seems that opening door disconnects oven from input power. Sometimes the switch is loose, or wires are not firmly pushed in the socket. If the power line wiring is loose, and by opening door looses contact with socket, it can touch metal housing inside, cause short, electric shock, serious even mortal injury and fire. This is dangerous high voltage switch, and to access it one must open oven from the back and take off the cover. I do not recommend doing it by your self.
Rem: Replacement micro switch is couple dollars.

Microwave will not operate (cook). F7 error code
appears on the display.
Electrical circuit interruption between L1 and Neutral in
the microwave inverter circuit.
Possible reasons:
1. Check door, hinge and cavity front alignment and adjust
as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves
the problem
A. Check the Cooling Fan for proper operation or
blockage
B. Check the resistance of the magnetron thermostat.
It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter
is properly connected to plug P2 on the display PCB
& Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W
inverter.
8. If problem persists, replace control assembly.

Please let me know if you need any more help or have further questions about anything that I have posted. I would be glad to help

thanks

FMV152KWA microwave buzzes when not running


Missy Uhland Bauman,

I understand that you are hearing a buzzing noise from your microwave, even though the door is shut and and it is not running. I would suggest to give the appliance a hard reset. You will do this by either unplugging it or cutting the power off at the circuit breaker for 3-5 minutes. After the 3-5 minutes, bring power back. If you are still hearing a buzzing sound, I suggest either contacting the manufacturer or your local authorized technician.

-Best Regards-

GE Spacemaker XL 1800 Microwave. After removing heated food, I closed the door and the microwave sounded like it was powering up again. However, no internal light came on as it does when the unit is...


Be sure to keep this oven unplugged or the door open until it is fixed. If it runs by itself, this is a fire hazard.

First listen carefully for a buzzing sound behind the control panel when the door is shut.

If it's present, chances are you have a failing capacitor on the control panel assembly, which can be repaired for $39.95 in most cases. Details are here.

If that or a louder buzzing is only present when you have the door closed, then the oven is cooking when it's not supposed to, but the cooling fan is not on, and it is overheating and tripping the breaker.

That would be due to a shorted cook relay on the control board. That can also be repaired with our $39.95 service.

The odd characters on the display concern me separately. This could mean you have a noisy or otherwise failing magnetron.

If the display is fine when you're cooking properly with it, then the magnetron is probably okay.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

MICROWAVE WILL NOT HEAT. F9 APPEARS IN THE DISPLAY WINDOW


F9 indicates a problem with the door latch.  There is a safety switch that will not allow the microwave to operate if it detects the door is not closed properly.  Even though physically it may seem the door is shut, the safety switch is not relaying the message to the onboard computer.  You need another door latch switch.

Buzzing noise, wont work???


The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

Microwave won't work


F6 usually means a fault in the controller or keypad. You could try to unplug it for several minutes, then plug it back in. If it still fails, maybe you or a friend can disconnect the power cord, unplug the keypad strip internally, then plug the power cord back in and try it with the keypad still disconnected. If it does not fail again, you have a wet or shorted keypad and can dry it or order one. If it does fail again, the control board is bad. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383 Sorry I didn't get to answer this before the bogus answer was posted. I've been tied up and away from the PC.
