JE1840WB01 General Electric Microwave - Instructions

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.

Replace the fuses

Unit was painted inside recently, but apparently some paint fumes still lingered so that when the unit was turn on, there was a very small explosion that took out the flam sensor thermostat. This thermostat interrupts the white leg of the AC input and cuts off all power.Performing a continuity test on the flame sensor showed it was permanently open (no continuity). Turns out I had a similar part from an old coffee maker and when I installed this part, the microwave turned on just fine. So I order the correct sensor from Parts Select. Part installation involved removing the TT20 Security Star bits (4) and the right/left side phillips screws. Now the top/side unit cover comes off by pulling the cover backwards and up and out. The flame sensor is in the middle of the front section underneath the top cover, and comes out easily with pull-off connectors. There are also bendable pins that hold the sensor down flush to the top of the unit.

unplug the unit then pull down , lot of screws are on top. open the cover . you could see the parts that need to replace on the right hand side (heavy side). disconnect wires then test the parts that need to replace by a tester to make sure that it's really broke .then unscrew part and replace .

Just like the directions said. Very simple.
