PVM1870DM2WW General Electric Microwave - Instructions

removed the bottom panel (6 screws), disconnected the two power terminals, and losened the turntable motor. installed the coupler from inside the microwave, replaced the motor, re-connected the power terminals, and bottom panel.

Used a phillips head screw driver and loosened the lens frame under the microwave. Removed the broken lens and replaced it with the lens ordered. Put the lens frame back in place and secured it with the phillips head screw.

remove cover, unplug secondary door switch (top switch)
remove switch from holder, install new switch, plug in wires, replace cover, very easy. door switches are a common problem
with microwave ovens.

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

Replace the fuses

All one has to do is use a screw driver to remove the screws, one per lens.
Then lower the lens bracket, bend the 4 tabs holding the
lens, remove and replace the lens and screw the brackets back in place.

Less than 10 minuits.

Replaced the fuse. Result; did not fix the problem.

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

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.

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.

There are five Philips screws on the bottom outside cover .one at each corner and one at the front center. Remove all four at the corners .leaving the front center for last. When the last screw is removed ,the cover will hinge down, it is attached to clips at the back that allow it fold down. The wire attached to the light socket is connected by a pull apart plug. Grasp at each end of the hard plastic connector and pull outward ,DO NOT PULL ON THE Wires ! Lift the cover from the back of the microwave place it on a flat surface on a towel keep it from sliding around. Remove the screws holding the porcelain sockets. Reverse procedure to reinstall .Installing new Halogen lamps is suggested. Use a clean tissue or cloth to handle the lamps, finger prints on the lamp will shorten the life .

Watched How to repair a Microwave that turns on when the door is opened Video on the web. From this took a shot at the switch was the problem. When I removed the switch it was defective. The small button was in and when you turned the switch upside down the button would drop back into position. Ordered a switch for $25.oo , installed it and the microwave is working fine.

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.

Remove the microwave cover. Requires a phillips screwdriver and a torx security bit/nut driver (there are two security type screws on the back...guess they don't want you to do this at home!). I had to buy the a security bit set (about $7). The diode is easily accessible on the right side under the fan. Requires removing on small phillips screw and unplugging on electrical connection. GE provides some instructions in an envelope on top (after cover removed). There is a warning/instruction to discharge the capacitor before service. This was not a problem for me. Actual diode replacement took 30 seconds. Whole job = 15 minutes.

At first I thought it was just the bulb, but I wasn't able to find a video of the exact model. The dificult part was figuring out how the vent housing came off (turns out it slid to the left then lifted out) but after I figured that out, replacing the cable assembly and the bulb was really easy.
