CVM2072SM3SS General Electric Microwave - Instructions

Replace the fuses

after a couple of misfires, got the correct size tray, and replaced it in the oven.

remove cover-unplug wires from secondary switch-remove switch-snap in new switch-plug in wires-replace cover-works great. very easy to do.

Found blowup drawings inside unit, which helped identify what I had to remove. Had neighbor assist in lifting unit from wall mount, unit slides easily from rails once top bolts are removed. Pay attention to where all the screws go as you remove them, some inside assemblies will have to be removed or loosened. A good guideline to go by is all black screws hold internal assemblies, the bronze screws go in the back side and the chrome screws go on top, sides, and front of the unit. I was able to lift unit back on rails without any assistance.

Microwave would not turn on. Lights and fan worked fine. Before the microwave stopped completely, it would turn the microware fan on even when door was open. I read the reviews and they were exactly the same issue that others were facing. Once I opened the front panel and got to the switches it was easy to figure out which switch was bad as it was the one that was soft (When clicking it). It was hard to take it out though (it seemed stuck). So, I used a plier to yank it out. I put in the new switch and everything worked just great! I would like to thank other comments that were left on the site to make my task much easier. Thank you (to the commenters on PartsSelect), you not only saved me money, but also ensured that I learn about the microwave more and give me the confidence that I could fix it.

Had to take the MW off the wall, remove the cover, and find the magnetron. Issue was the HV-capacitor. Had to remove the diode and capacitor to discharge the capacitor safely. Crackle-Bang! Then put it back before toying with the HV-transformer in order to get the magnetron out. Took a little under two hours to get it back on the wall and a lot of cajones when monkeying around the chassis removing the capacitor. Not a job for most everyone as this was a potentially high-shock repair due to the voltage and micro-farads held in that capacitor. Hardest part was getting the magnetron to drop out past the HV-transformer. Also, the thermostat had to be removed from the magnetron and re attached to the new one. Fiddly delicate job, not for the clumsy or faint of heart.

Turn off main power bracker. Removed fan vent, removed control panel, disconnect leads to the three monitor switches. Replaced the secondary switch (top). Reversed procedures.

First unplugged the microwave, took top grill off, took control panel off, took wires off and used color coded tape to make sure they went back in right places, took fuse out and replaced it and put every thing back and it all worked fine and to top it off my wife did it all. So it was pretty easy.

Installation of the damper was effortless but removing the microwave, cutting holes vertically through an overhead cabinet then installing ducting with a ninety degree bend, through another cabinet, and then through outside wall consumed most of the time and effort.Your service, packaging, and timely (next day!) were extremely helpful.

damper plate was a snap-in part. rotated fan discharge to top of microwave. installed ducting to discharge food odors outside.

thank you very much.

Opened the microwave oven door, unscrewed two screws which held the control panel on, then I removed two of the door switches (each had two screws), and then used the continuity tester to see which one was not operating. It turned out to be the secondary door switch, replaced it and to my amazement, the microwave worked. I have never repaired an appliance before but I didn't want to replace our over-the-stove built in microwave. It was the best day ever when it was working again! The hardest part was getting myself to try the repair.

Removed the microwave with the buit in housing from the cabinet. Removed microwave from built in housing. Removed outer cabinet giving access to remove control panel and smart board where switches are located. Removed control panel to get to smartboard. Removed smart board after disconnecting a few wires to allow easy removal. Individually removed and then tested each switch using multimeter. Found seondary Door Switch (bottom of smart board) operation to be intermittent (switch trip button extremely loose and rattle inside this particular switch) Ordered replacement part which came very quickly on standard shipping order. Put new switch on smart board and remounted, reinstalled control panel and reconnected various wire connectors previously disconnected. Then plugged in oven and tested for opertation - didn't work at all! But, after bleeding off capacior charge by removing connectors and discharging capacitor to ground, then reassembling control board and smart board into oven, then trying agian, it has worked perfectly ever since. Do not understand why capacitor disconnect/discharge was required but suspect this reset the control electronics. Easy fix and hope to get another 12 years out of this appliance which is used multiple times every day. Also have two other identical micorwave ovens, one is 20 years old, but these get used relatively infrequently.

removed access panal, found soft switch as discribed on your web site. removed and replaced.

It was great...Thank you for having the part available...
