A potato caught fire and now my microwave won't work ...is there anything I can do to fix it???

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.

If your microwave is not a convection then the moisture most probably is somehow getting to the controls as potatoes has quite a bit.

I would make sure it has no burnt wires from the heat. What kind do you have Larry?

When cooking a potato in the microwave Without puncturing it with a fork... it definitively EXPLODS braking the CAROUSSEL PLATEAU and probably damaging some delicate electronics inside, (you have to pearce the potato with a fork to let steem out when cooking) if you are lucky it could be just a blown fuse inside, have it checked by a proffessional (there is normally no reset for a microwave oven exception maiby for the control panel)

Good luck!

Hi,

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.

Fuse is behind the control panel. Has cavity sensors and a magnatron thermal disc also. Start with the fuse and then pull it down if not the problem. Eric

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.

Hello, inside most microwaves, there is a thermal fuse, that if something in the cooking cavity is on fire, it will melt the thermal fuse, if it gets hot enough, thus breaking the power to the unit shutting it off. This sounds like what has happened to yours, simply replacing it will correct the problem. It is usually located near a cavity exhaust point. If you aren't comfortable doing this, as it requires removing the outer cover, while unplugged, and locating/replacing it, take it to a appliance service co. This will of course cost more, if you do it yourself, make sure you provide all of your make/model/serial/anything else, that will identify your unit, and call/go online to a parts retailer, and you should be able to get it done fairly cheap.

Hope this helps, and thank you.
