PVM1870SM1SS General Electric Microwave - Instructions

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

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

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.

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.

thank you very much.

removed access panal, found soft switch as discribed on your web site. removed and replaced.

Simple, simply lifted the old piece out of position and dropped the new piece in. A small part of the broken old piece must have fallen away and is still in the unit, but it has not gotten in the way of the new piece doing its purpose

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.

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.

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

removed the bottom of the microwave and removed the motor and replaced the coupler and reassembled. Easy repair.
