PVM1870SM1SS General Electric Microwave - Instructions

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.

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.

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

Lifted off the glass turn table and just pushed the new plastic couple onto the drive post. The plastic coupler is splined, so just sit it onto the drive post and lightly turn it until it starts to drop and give a little downward push. That's it - about 30 seconds and the table is turning again.

Just replaced the old and broken one

Went on YouTube and found an example of my problem and watched it! That's how I knew which part to order. The part came within two days of ordering and I installed it within 10 minutes. My husband was so proud he told all the guys at work!

When we moved into our recently purchased home, I noticed that the turntable in the microwave wasn't turning. I discovered that the coupler was missing and hoped that nothing else was damaged and that getting a new one would fix the problem. I ordered the part and it came the very next day, even though I got 3-5 day shipping. Didn't even have to unscrew anything to install it. It popped right in and the turntable works perfectly now.

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.

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.

Threw the old filter away and slide the new one in without any tools ! Filter should be cleaned every month - who knew ?

1. Unplug the microwave or switch off the breaker to the microwave. 2. Unscrew 5 screws on the bottom plate of the microwave. The plate swings down by the hinges on the back. 3. Unplug the wires leading to the turntable motor and make note of which color wire goes on which side of the motor plug. 4. The initial instructions said unscrew the screw holding the motor but my model has two screws. Remove the screws and lower the motor. 5. Insert the plastic coupler from inside the microwave through the hole in the center of the base. The coupler has a half moon shaped female shaft that connects to the male shaft that extends up from the motor. Slide the motor shaft into the plastic coupler. 6. Replace the screws that hold the motor onto the base of the microwave. 7. Plug the power wires back into the motor with the wires in the correct position as noted above. 8. Plug in the microwave and turn it on to check if the turntable now turns. Mine did not at first so I unplugged the microwave and the motor wires. It turns out you can plug the motor wires in and they don't connect correctly. I reconnected the motor plug and plugged the microwave back in and turned it on. This time the turntable was working. 8. Replace the five screws on the bottom plate of the microwave. Done.

I followed the online instructions.
