Question about Microwave Ovens
Microwave is not heating I have a Frigidare model # FMT148G1B2 and everything comes on, but it will not heat. This microwave is about 8 years old.
Chances are the problem is a loose connection on the magnetron, a bad high voltage diode, or a bad diode.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
