JVM1870SF02 General Electric Microwave - Instructions

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.

I could not for the life of me figure out how to get into the light housing so I could replace the bulb, nor did I have any idea which bulb to buy. The manual for this model descibes how to replace the underside lighting but they seem to have left out instructions about the interior. I watched the short "how-to" video on this site, bought the bulb that was described and replaced the bulb in five minutes without any issues.

Just replaced the old and broken one

Rec'd the parts within a day or two after ordering and simply placed them where the old ones were removed and wala my stove is back filtering. Only problem, the oven won't ignite while the broiler and stove top burners are fine. Go figure.

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

I ordered this part from Part Select for my GE Microwave oven after Googeling it from the model number. They had the lowest price, so if you are reading this, just go ahead and order the part, you won’t find it any cheaper.

As far as the repair goes it was the easiest repair that I think I have ever made. It took me longer to unpack the part than to instal it.

There are two screws on the top of the microwave that hold the assembly in place. Just remove those two screws and slide the assembly to the left as there are three small hooks on the bottom that hold the bottom in place. To install the new assembly, I simply lined up the three bottom hooks and slid it to the right and replaced the two screws on top. I tested it and it worked perfect. Only tool was a Philips screw driver.

My only criticism is towards GE for designing the part this way. I seems to me that the two springs that hold the door shut have to much tension which causes the part to break. Seems like just making the springs with a little less tension or stronger spring attachments would solve this problem.

In our case getting access to the charcoal filter is complicated because the unit is mounted under an overhang of the kitchen cabinet.

slipped them into place by hand

I followed the online instructions.

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.
