PNM1871SM3SS General Electric Microwave - Instructions

First I removed the two screws that held the filter cover in place, lifted out the old and replaced it with the new filter. Put the filter cover back on and replaced the two screws that hold it in place, and it was done in less than 5 minutes.

I just followed your instructions that came with the filter removed the screws and slid the cover to the left

Received part installed in less than one minute, easy fix alignment of part in shaft pressing down into position

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.

This microwave has two separate spring-loaded latch pawls. To get the broken latch pawl off and install the new one you first take off the rectangular plastic trim piece from the inside of the door to expose the pawls. There is a pin that secures the pawl in place. To get the pin out I had to carefully drill a regular hole bigger than the pin with the Dremel tool at the edge of the plastic door piece. I then could extract the pin with a small screwdriver or twizzers. The old pin and spring will come out and you reverse the procedure to install pawl and pin and connect spring. Then reinstall trim piece. I put a small piece of black electricians tape over the hole I made in the door edge. It doesn't show when door is closed and it blends well with the black plastic edge. Test to make sure microwave works and mine did after some carefully fitting of the trim piece.

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

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.

Followed the easy directions that came with the replacement filter

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

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

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.
