PVM1870SM3SS General Electric Microwave - Instructions

PartSelect had helpful repair instructions on-line which made the repair easier and faster. Unfortunately, there were other problems with the oven that immediately blew the new fuse I had just installed. It was then determined that additional repair would most likely cost almost as much as a new microwave.

Uninstalled microwave from above range, removed cover then vent assembly (slide slightly to the left to free it). Opened the control panel (slide up then tilt forward) to access the troubleshooting/repair/test sheet. Followed the diagnostic flowchart and determined the TCO above the cooking cavity had failed. No other faults found. Ordered part Sat. afternoon and rcvd it Monday. Part is held in place with spring clips and quick connect terminals so installation was easy. Microwave was back in operation in no time.

Turn off main power bracker. Removed fan vent, removed control panel, disconnect leads to the three monitor switches. Replaced the secondary switch (top). Reversed procedures.

thank you very much.

Very simple it took me less than 5 minutes to fix it.

First unplugged the microwave, took top grill off, took control panel off, took wires off and used color coded tape to make sure they went back in right places, took fuse out and replaced it and put every thing back and it all worked fine and to top it off my wife did it all. So it was pretty easy.

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

Just replaced the old and broken one

I replaced the cover just fine but i think a sensor went bad

Replace the fuses

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

Removed the above stove microhood. Removed the side panels & the top panel. Diode located on right hand side of microwave. Removed with screwdriver & replaced new diode. It's best to get the microwave schematic online to pinpoint location of the part.

I followed the online instructions.

All I needed to do was remove two screws, then dig out the broken plastic from the metal guides on the microwave with a knife. Putting the new grille in was easy, just align the clamps and push. Then replace the screws.

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.
