PVM1870SM3SS 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.

-unplug
-remove top and front covers
-unplug wire connectors from heating assembly
-remove heating assembly from metal stand and push out of the way
-remove metal stand from dry
-pull out heating assembly
-install new one in reserve order

I first read the previously posted directions from other customers that were sent with my part order confirmation, which were all very helpful. Then, I basically used a screw driver to unscrew the screw holding the lens cover in place - be careful as it is a very tiny screw and it can easily fall behind your oven. You might want to place a large piece of cardboard over the space between oven and wall, as I did, so that you don't lose the screw in case it falls. Next I pried open the prongs, carefully slid out the cracked lens, and slid the new lens in place, pushed back the prongs and put the screw back in. I found that it was easier to use my fingers to first place and tighten the screw because it is very small and will keep falling out of place if you try to just use the screwdriver. Good luck!

placed plastic ring under glass rotating plate in microwave

I took the cabinet off and saw where the switch had been burnt. So I remove it and order another one from your company. And I put new clips on it with heat shrinks. We might get another 30 years out it, Although I'm 80 years old.

The part received was defective and I will have to use a rotary Dremel tool to grind down plastic that wasn't properly formed during the injection mold process. This will likely take several attempts to get it properly shaped in order to install the vent grill as it currently prevents the part from sliding left to right behind the slots in the microwave hood.

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.

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

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.

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.

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

Removed three screws from the top front cover and slide it out and following I removed the touch panel and the housing that holds the switches and replaced the bad one.
