Oh dear, I hope the magnetron still works. That plate you describe is called the Waveguide Cover. This cover must be kept clean otherwise the food particles will carbonize and cause exactly what you have described.
Contact the manufacturers web site for a supplier in your area or look on ebay, espares.co.uk depending on your location.
When it has been changed, I hope the magnetron/aerial is OK.

Replacement or fix


just replaced our 6 year old Thermador MBBS ($750) with a GE JES2051SNSS from Home Depot ($179). The bottom guide piece from the Thermador bolted right on the bottom of the GE and positioned the new unit so the front trim piece fit perfectly.

Mbbs 01 thermador micro oven: timer counts down, lights go on, but no heat, no fan and turntable does not turn. is it a fuse?


Key clue is table does not move---All microwaves with a table have a lever switch that is engaged when door closes--only can get at from inside the unit----it prevents the unit from operation if door not closed.

What happens from closing door a lot is the switch with a lever arm can come loose or even if snapped into a plastic holder break out of the holder.

IF this it is not too expensive a repair.

Buzzing spark / flashing


The magnetron is most likely the problem, it heats the food and is the heart of the of the microwave oven, if it was followed by unusual odor more noticeable when you open the door that would confirm it, but that is not always the case. The cost to repair would exceed the cost of a new one

Sparks


Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron.

You should be able to order one here.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

Microwave appears to work fine but will not heat at all.


Sounds like the thermal protector on the mag tube quit. It may have gotten too hot and opened up. That is the lesser of all the evils that can happen to a Microwave.
