Frigidaire FMCB115GC Microwave Oven wont stop

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

The owner's manual will help you, I'm sure.

If for some reason you don't still have yours, you can download Frigidaire owner's manuals and installation instructions here.

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.

The symptoms of loud noise and no heat indicate a short in the magnetron or high voltage diode. Need to take it to a qualified repair, to figure out what the problem. The magnetron replacement can cost as much as a new oven. See what the warranty covers, maybe you might luck out.

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.

Generally the magnetron (the part that heats the food) is the cause if everything else still works and it only works once in a while, possibly a short, but not as likely. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

Could be a blown fuse in the HV transformer primary circuit,bad connections to the magnetron filament,open thermal protector or thermal fuse,
