Sorry to read about your problem, I hope this helps you out.
here are some problems you may have.

1. No power to outlet (blown fuse or tripped breaker or GFCI).
2. Blown main fuse - likely due to other problems.
3. Open thermal protector or thermal fuse.
4. Defective controller or its power suppy

Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair.

If this one has an FCC number beginning in "APY" it was made Sharp and this is almost always the bottom door switch or its mount.

I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.

The only parts that are available for this unit by model number are the tray inside and the feet on the outside.

If you were adventurous and found a way to take it apart and remove the door switches you might be able to match them up at an appliance parts dealer but short of that it sounds like a lost cause.

I know that is not what you want to hear, and I as well do not like being the bearer of bad news.....

My 2021 Frigidaire also turned on by itself 2 days ago. It also got hot and would not turn off except at the breaker. After 10 minutes I turned breaker on and the microwave was still on. Turned breaker on the next morning and all good. We are afraid to leave house unless we turn breaker off. Any suggestions? Do I need a new microwave?

I would check the door switches.

The control board probably has failed.

fuses inside oven, sure. (i had to guess) all UWAVE do that when the 3 or 4 door switches CONTRADICT. this is so it does no cook a persons eyeballs.(no really ) what we do is replace them all as a set, 4x5=$20 set. I am on my 3rd set here, ( 18 year span) so i even bought a new whole spare fuse panel (behind the controller) with new switch set pre loaded.all -in- one fix. then when it fails i can replace it all in 30min flat. mine is built in fancy uwave and do not want top put in any alien Uwave here and now wood cabinets must be modified. see? good luck,

Question edited for clarity. No you can't. The turntable needs to rotate the food or the microwave energy will burn holes in your food. The rotation spreads the heat evenly throughout the food. You can test it by removing the turntable and put a plate on the base with a pound of butter on it. Microwave on full power for a minute. Notice the holes?

It sounds like you may have an issue with the plug that connects the microwave portion of your Frigidaire PLEB27M9ECD built-in oven/microwave to the electrical supply. Here are a few things you can try:

1. Check the power supply: Make sure that the oven/microwave is properly plugged into a working outlet and that the circuit breaker is not tripped.
2. Inspect the plug: Look for any visible damage on the plug and make sure that the connections are secure.
3. Check the wiring: Make sure that the wiring inside the oven/microwave is not damaged or loose.
4. Test the outlet: Using a multimeter, test the outlet to see if it's providing power.
5. Test the microwave: If you have access to a known good microwave, you can test the plug by plugging it into the known good microwave and see if it works.

If none of these solutions work, it's likely that there is an issue with the electronic control board or the plug itself, which will require professional repair. It's best to contact the manufacturer or a professional technician for repair. They will be able to diagnose the issue more accurately and repair it.

F3 means the key pad is faulty. Probably replaceable if you can find a service agent in your area/town/city/country.

Try cutting the power to it for 15 minutes to effect a power reset to the mainboard. It is still does it, you need a service call or a new one. It is a known issue. https://www.google.com/search?q=Frigidaire+Gallery+microwave.+The+internal+light+and+internal+fan+stays+on ..

The sounder is an integral part of the control board.

I had the same problem with this POS microwave. Bought it September 2019 and the plastic at top is brittle and breaking plus the door latch springs are WAY too stiff for this application. I'm 6'4" and it is hard for me to open and close. The spring tension causes the latches to slam down on the thin edge of the plastic catch causing divot wear. The INCESSANT beeping when food is done is worse than nails on a chalkboard plus there are Way too many levels and button presses to simply soften butter or cream cheese! What a TOTAL mess that I Absolutely regret buying! As for this issue with the blown fuses (on a 20 AMP circuit with nothing else on it); I read about replacing the switches so that is where I started but it didn't work. I noticed the wear in the latch catch so I ordered a replacement and that fixed the problem. I also found a video showing how to remove the door and change the latch. I did not need a new latch, but I did want to replace the spring. I have a box of springs at home and found one that was slightly shorter but the same diameter. It had about half the pull strength and now the door opens and closes reasonably! I hope this helps

Time for a new one!

You are lucky! MICROWAVE OVEN LIGHT Remove the louver per instructions 1-3 above and charcoal filter, if used. 1. To replace light bulb, first disconnect power to the microwave oven at the circuit breaker panel or by unplugging. 2. Open light cover located behind filter mounting by carefully pulling up on the front edge. 3. Remove old light bulb and replace only with equivalent watt bulb available from parts distributor. Bulbs are also available at most hardware stores or lighting centers. DO NOT USE BULB LARGER THAN 20 WATTS. 4. Replace the microwave oven light cover by carefully pushing into place. Replace the charcoal filter, if used. Push the louver back into place (engaging both the bottom and top tabs) and replace the louver mounting screw. When in doubt, refer to the manual :>D https://d1vofmza27mmhi.cloudfront.net/product-pdf/frigidaire-fgmv174kf-use-and-care-manual.pdf ..
