    Thanks so much - everyone else kept telling me I needed a service person to change a light bulb.You saved me a $90 service charge.

    I apologize for being dense, but to what does "the outer cover (wrapper)" refer?  Does this mean the microwave unit must be removed from the cabinet to access an "outer cover", or does it refer to something inside the microwave?

The outer cover (wrapper) will need to be removed.

The screws you need to remove should be pretty obvious, and a special driver (such as a T20H Torx type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

The bulb is located in the top side of a plastic or metal duct located on the right side of the cooking cavity.

The bulb is common and can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

That would be your waveguide cover. If damaged or discolored, the waveguide cover has been damaged by heat and must be replaced.

It protects your waveguide and magnetron from arcing due to grease and food particles.

The area of the waveguide behind the waveguide cover should be clean, and if rust or flaking is present it must be sanded, then repainted with high temperature appliance paint.

For Dacor model DMT2420S, the waveguide is part number 66345 and you can get it from The Pros here for $11.07 (subject to change).

The service manual is at my site here: http://www.microwavecontrol.com/dmt_2420_sm.pdf and the part list is here: http://www.microwavecontrol.com/dmt_2420_parts_list.pdf.

We have a Dacor Microwave DMT2420S that everything works except the Touch Screen doesn't light up.


The display board is bad, it may be part of the control PCB or it may be separate. Some are back lit and some are lit internally.

Light Bulb Change


If there's no obvious removable cover over the bulb (most often on the rear or side) and the owner's manual doesn't address it, then disassembly will be required.

You'll need to remove the outer cover (wrapper) to get to the bulb.

Always unplug a microwave before removing or installing any bulbs.

See these links before proceeding:

http://www.microwavedisplay.com/disassembly.txt

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.

If not, chances are you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download Frigidaire owner's manual and installation instructions here.

Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.

The screws you need to remove should be pretty obvious, and a special driver (such as a T20H Torx type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.
