SOURCE: burnt spot

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.

Sparks inside the microwave when power is turned on


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

It may also be in the area of the turntable support, coupler, or motor.

The waveguide cover (also called a spatter shield) 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 your waveguide cover is burned, it will need to be replaced.

It provides critical protection for the magnetron.

The service manual is here.

Let me know if you need further help.

Hey, i just used my dacor microwave and sparks/fire came out of the patch like object on the inside of the microwave...any idea what the problem is??? thank you


Probably just lack of cleaning.

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


It may also be in the area of the turntable support, coupler, or motor.

The waveguide cover (also called a spatter shield) 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 there is any damage to the cavity, the area will first have to be sanded smooth and cleaned and dried thoroughly.

If the cavity metal of the oven is cracked or split, you can use a small amount of steel-based epoxy such as JB-WELD to patch the crack or hole.

Once that dries thoroughly, you can sand it very smooth.

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 critical protection for the magnetron.

You can order Dacor parts by part number from the Pros here.

I would have been happy to link to the service manual if you had provided the model number.

On the off chance that it's a DMT2420, the service manual is here and the parts list is here.

there is a component called a spatter gard inside the oven at the point where the microwaves enter......if food or other foreign substance gets stuck there, then it will start to burn ...the smell and popping noise is coming from the spatter gard.....to fix it you must remove the spatter gard..replace it if it's burnt and /or sand paper the spot clean and then paint the area with a high temperature paint called mr. touch up......to protect the bare metal from the microwaves.....hope that helps

Not just once, twice!


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

The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.

In some models it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.

Your manual should address the issue of removing and cleaning the waveguide cover.

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

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.
