GLMV168 Frigidaire over-the-counter microwave oven. My wife inadvertently let it run for about a minute with steel utensils in water in a glass jar along with plastic dishes. She says there was a small contained fire which she quickly extinguished by removing the revolving tray and pouring water on everything in the kitchen sink. The plastic dishes were partially melted and appear to be the only thing that actually buirned. There doesn't seem to be any external damage or evidence of fire other than the odor, but now the unit does not run and the LED clock is blank. There was no circuit interruption and the circuit tests OK. Any suggestions that might restore this unit to serviceability?

The magnetron will have overheated and will need to be replaced. Also, there is a thermal cutout mounted on or near the magnetron. It will need to be replaced, too. You can find exploded views and order parts here: http://tinyurl.com/gv383 What you'll need are the parts marked as reference numbers F73 & F74 (73 & 74) on diagram number 6. You might also be able to find cheaper substitute parts at a local applaince parts store.

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)
