20 Most Recent Dacor DMT2420 1200 Watts Microwave Oven Questions & Answers

I see (and repair) this a lot. The problem is on the controller assembly, which I regularly repair. Details are here. This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller. The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too. FixYa doesn't notify me when there's a response, so if you have other questions, please contact me directly. - William E.

Look in side and make sure there is no pieces of aluminum foil or metal hidden inside. If not I would not use until you have a appliance repair person look at it.

Other than size and cosmetics, the DMT2420 has a touch screen.

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. 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. 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. The service manual is here and the parts list is here.

You can get that repaired for $39.95 in most cases (details here) or (assuming your model is DMT2420 since that's where you posted) you can order a control / display unit here for a little over a hundred dollars.

That's probably the door open lever or door open button, and there may be grease where the button passes through the control panel frame. The service manual is here and the parts list is here. You can order Dacor parts by part number from the Pros here.
