Was microwaving a hotdog on a paper plate covered by another paper plate and the microwave just kind of went poof and now nothing lites up (display) and it wont work. I checked the breaker it is on and that is fine. Is there a fuse in the Microwave that might have gone bad?

There's likely a burned fuse inside the unit.

Yeah a kind of. If the wave cover plate is only went bad(A rectangular plate inside the food chamber).
If you have little idea how to use voltmeter then only you can try to fix it.Otherwise,without any experience it is very risky.
First check the magnetron which produce microvave.(check two terminal resistance in isolated sysem).MAKE SURE YOU DISCHARGE CAPACITOR FIRST .MICRVAVE CONTAINS 5000V IN IT.

If magnetron is good then just clean the wave guide and replace the rectangular plate(wave cover).

it should work okay then

Thanks

Hi

To locate the inlet cover, look towards the interior side of the microwave next to the microwave display. The inlet is typically located near the back of the microwave, in the middle of the wall.
Unplug your microwave from the electrical outlet and remove any food or containers.

Wipe the inlet cover, typically located on the right side of the microwave in the middle of the wall, with a damp cloth. The cover must be kept clean or it will not protect the microwave.

Dry the inlet cover with a soft towel.

Leave the microwave door open for several hours to air out the inlet cover.

Examine the inlet cover for wear and tear. If the cover has too much damage in the form of scratches or holes, it may need replacement.

Remove the inlet cover, if desired. Insert a putty knife under the plastic nail that holds the inlet cover in place. Pry out the nails and set them aside. Pull out the micro plate in front of the inlet and set it aside. Remove the inlet plate.

Install a new inlet plate. Slide the new inlet cover into its place. Replace the nails back into the side of the microwave by aligning them with the holes of the side.

Time for a new cover plate or a new microwave. Depending on the age of the unit, the part may not be available anymore.

Its high voltage side is worn out. It can be repaired buts its probably cheaper to just buy a new microwave oven.

You can get that repaired for $39.95 in most cases (details here) or order a control / display unit here and replace it yourself for just over a hundred.

Hi, you must check the inside fuse. If is burned out, please consider that something happened, you must check further beyond to find the causes.

Was the ceramic plate part of the microwave or a plate form the kitchen?

If it wasn't the microwave plate, it should be fine. You should be able to be sure it's all clean and use it as usual.

A microwave oven should of course never be left running unattended, especially when using any paper products.

Paper plates and paper towels can sometimes have small amounts of impurities which can ignite.
