Frigidaire microwave runs but no heat

it may be a diode or capacitor check these first

Microwave frigidaire model GLMV168 will run but does not heat.

Not what you want to hear but the voltages in there are seriously high. Normally the Capacitor and diode are faulty due to dirt build up and very possible the magnatron is als the culprit. One needs to have some good testing equiptment to source the problem. If you insist on doing the repair, buy the magnatron plus capacitor plus HVdiode and install as you remove the faulty components.(do not make a mistake with the wiring)

When I want to cook something the light turns on, the timer starts counting down, but the motor does not run. No cooking.

I have always found replacing the magnatron assembly as well as the high voltage fuse is normallly the best way to fix this problem. Good Luck,

Microwave not heating everything is normal

The fuse for the Litz coil and magnatron tube is blown or the tube has gone belly up. Open it up and look for the fuses and replace them. If this does not work it is more economical to buy a new one.

Over the range Frigidaire Microwave not heating. Model FMT148

This is a sure sign that the MAGNATRON needs replaced (this is what heats up the food) if every thing else works but food not cooking! 99% of time it is the magnatron!
Please rate answer!

Frigidaire Microwave will not heat and is a little louder than usual.

High voltage parts are suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!
