I have a Frigidaire microwave model FMV156DBB. The microwave light comes on and the timer counts down but there is no fan and no microwave. Can I repair this microwave without having to replace it or go to an outside vendor?

BAD DOOR SWITCHES AND UNDERSIZED WIRING TO THEM

If the inside light comes on when you try to cook, but the turntable and internal cooling fan do NOT, then that's a bad bottom door switch or that switch's mount.

See this helpful text file.

If the inside light, turntable, and internal cooling fan DO all come on when you try to cook, but it does not cook, then you have a bad relay or connection on the control circuit board, which we can repair for $39.95. Details here.

We have the service manual and have uploaded it to our site here to help you.

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.

Check the plug. If the vault is 110v or 220v etc.

If the plug seems to be right, but still not
working, you should buy a new one
with a good name brand you can trust.
It's better than paying for repairs and future repairs.

check fuse inside inline with black wire and micro switches on door locks

thumbs up

check or replace magnetron

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

The 'Clock, is Machanical just like an ordinary kitchen timer The reast of it is electronic, and at that age time for a new one.
