DVM1850DM2WW General Electric Microwave - Instructions

My microwave is built in above the stove which provides lighting and fans for my stove. The glass lens cover for the lighting was cracked in several places and the light bulbs had burned out. I taped the glass lens for removal so it didn't break apart due to the cracks Removed the one screw. .Both light bulbs broke away from the base sockets as I tried to unscrew them. I used electrical tape wrapping in reverse on a lightbulb (socket end) so it was sticky for a grip on the base, shoved it in the sockets and was unable to unscrew the broke off bases. So it was very successful and no repair man was needed.

I ordered and replaced the coupler. Once installed, all was well!

Removed the outer cover to access the door switches. Turns out there were three switches, but I determined that only two were bad. When the small colored tab on the switch is pushed in it should make a clicking sound. The two bad switches had no resistance and did not make any noise when pressed. Removing the switch is relatively easy, you simply pull it away from a couple small tabs holding them in place. After reconnecting the wire leads, insert back into the holding tabs and install the cover.

This is sometimes described in other repair notes as "microwave 'runs' when door is open."
With power disconnected: Remove the microwave's metal grill surround. Three lower screws accessible with lower oven door open. Two screws accessible at top of microwave door opening with door open.
Remove microwave control panel: Remove two femaleTorx head screws (#27?) that secure the panel, accessible at right side of door opening. The right side of the control panel is secured by plastic tabs fitting into slots in the oven frame. Take good care to note how these tabs disengage from the slots (lift and shift). Tab breakage very possible! Once disengaged, the panel hinges outward and downward and is self-supported. It may be necessary to guide some of the wiring out of the way to fully lower.
There are three door switches, one "monitor" and two "secondary" switches. All switches are housed in a plastic frame, which must be lifted out of position for access, each switch is retained by flexible plastic, breakable-looking hooked fingers. Also note that the electrical connectors have tiny release tabs that must be depressed in order to pull them off of the switches. In my case the topmost switch, one of the "secondary" switches, was clearly bad since there was no "snap" or click when pressing the switch's button. Maybe you can determine which switch is bad before proceeding but I had ordered all three to avoid going through this exercise again any time soon.
Replace switch or switches, place switch carrier back into position and otherwise reverse the disassembly steps.

The halogen light bulb took a little skill. The prongs were a little difficult to maneuver into place.

Easy peasy - removed lens holder w/screw driver. Cleaned cover after removing damaged glass lens. Then unscrewed burnt out light bulbs. Installed new bulbs, slid in new light lens into holder and screwed back into bottom of microwave. Removed greasy filter and slid in new filter. Done!

Pulled it from the wall remove the front vent covers removed the control panel remove the door switches by a special screw driver bit which looks a star remove the electrical terminals pressed the plastic clip pulled the switch replaced it with new one then followed initial steps backward

I finally found the two screws to remove the fan opening. Once I did that I did not locate an OLD charcoal filter!! I just deducted there was never one in there, based on where the instructions said it should be located. I placed the new filter and let it "rest on an angle" as per the instructions I read from the diagram, and from the other peoples description online. I put the breaker back on and all seems fine!

I unscrewed two screws on top of the microwave, slid the part (which opens when the microwave is in use) to the left and put it aside. The old filter is then easily picked up and removed. I placed the new filter in the same spot. I repositioned the removed part in place, lining up the little tabs, slid it to the right, which automatically lined up for replacement of the screws. These directions were included with the new filter and it was very easy to follow. I can't believe anyone would pay someone else to do this simple task! I am a 67 year old female.

Unscrewed bottom of unit; dropped it down. Replaced bracket, scocked and bulb. Easy job with the right parts.

I took the part out of the box and handed it to my wife and said "here ya go hun, go put this under the glass turntable in the microwave. You'll know it's installed when you hear it click down" She yelled back, "easy as pie" - - - Humm.. I can't make a pie. Fortunately the old one was in one piece as the side just split so it slid off very easy. The new one just snapped in place.

unscrewed the screw, pried up metal tabs that hold in light lens. took out broken pieces, slid in new light lens re-secured tabs with fingers, screwed in the screw again.

I went to your site and looked up the schematic parts list and determined how to remove the grill and install the filter. I had the grill off and when the filter arrived I put it in, replaced grill and screws and then in about 20 min had the microwave installed on the wall and operating. By the way the part arrived about three days earlier than estimated. Thanks for your prompt response. You are on my favorites list for future appliance parts.

Simply removed screw, pulled down light holder, unfoled the metal tabs, took out the broken pieces and replaced the glass lens and light bulb.
