PVM1870DM1CC General Electric Microwave - Instructions

The breaker was tripped but fuse was ok on testing. I kept the fuse for possible future repairs. To access door switches and fuse on this model JVM1850CF001, remove 2 phillips screws at top. Then slide the grill to the left (toward hinges) about 1 cm and it should easily come off forwardly. Remove phillips screw underneath grill attaching the main panel. Lift the panel 1 cm and it will easily come off forwardly - I let it hang by the electrical cords. Now you can see/discharge capacitor(s). Remove 2 star screws inside door to loosen/remove/access door switch frame. 3 switches are held in the frame by plastic tabs - one tab per switch. One is primary and 2 are secondary door switches. I removed each switch one at a time by lifting tab, pulled off the electrical connector and filed the male metal connection on each switch. I replaced the switch with a loose button (loose and didn't click as crisply compared to the other switches) with a new secondary door switch. It was the lower secondary switch. Worked like a charm after that.

Removed one screw, installed new lense in lense frame, rescrewed. Done.

Simply installed new cam louver to microwave with two screws. End of job!!

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.

Replace the fuses

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

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

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.

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

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.

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 .

Once we figued out that you had to remove the panel underneath the microwave, pull down the turntable motor part and then insert to coupler it went really fast. Through trial and error we figured it out, but should have checked for installation instructions on the internet. Repair time would have been less than 15 minutes.

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.
