Overcooked a potatoe. caught fire. Micro wave does not show any signof electrical connection but electric sorse is ok. Suggestions?? Larry Tonini 916.677-6180 [email protected]

There may be a weakened connection around the main power supply 'Transformer'. Sometimes the connections can overheat but if they are removed and replaced it may again make contact. I've had a similar problem and found parts from similar brands to replace the connecting/wiring parts. I soon realized that I could have removed the extra pieces around the wires without causing any electrical problems. That is the minor repair. The major repair would be to replace one of the main features (large or small) which assist the transformer in power functions. Take your time examining the tiniest parts and pieces.

I haven't heard of such a thing. You must have cooked it until there was no moisture left in the potato. That would also account for the failure of the oven. It would be the same as no load in the oven.
A thermal protect part is your current problem.

the magnatron super heated the paper combined with what we in the industry call super combust your micro should be ok to use just keep it clean and if you use toweling wraP it around rather than cover

It may have dried out from over cooking.

This is common in potatoes, popcorn, and other low-moisture foods.

The manual will tell you about that, and it will also tell you not to leave a microwave unattended while it's running.

The owner's manual warns of the dangers of overcooking potatoes and similar foods and not to ever leave the oven unattended while it's running.

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

Are you looking for help to get your microwave working again?

Chances are it's just an opened flame sensor (cavity thermostat / thermal cutout / T.C.O.). Its job is to cut power if there's a fire.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

Accessing some components for testing and possible replacement (like the oven cavity thermostat) will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

use a scouring pad.

After washing you need to poke holes in potatoe skins or the steam can cause them to explode. Cook potatoes no longer than 6 to 8 minutes depending on your units power.

Microwave ovens can be very dangerous if damaged, so you will be safer to replace the unit. Better safe than sorry. Service on microwave ovens is not cost effective, and the newer ovens are very reasonable.

The magnetron probably overheated, blowing the thermal cutout / thermal fuse / thermostat mounted on it.
