JES1339WC04 General Electric Microwave - Instructions

Removed microwave cover using screwdriver and anti tamper bit available at local hardware store. Megnetron had broken magnet making discovery of deffective part easy. Removed wire connector and three screws attaching magnetron to case, removed magnetron and installed new item in reverse order. Installed cover and made popcorn for operational check of microwave. Happy days..........

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.

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

I went on line, put in microwave repair and watched a video on repair. I then took the oven down from over the range and took it apart. I could see were the magnetron had burned out. There was a hole with obvious burn marks. I went on line looking for the needed part. I clicked on PartSelect and order the magnetron. I received the part within three days, regular shipping. As I had not put the oven back together it took only a few moments to save 150 to 200+ dollars. I put it back together and happy, happy me, it worked.

Just like the directions said. Very simple.

I have the built-in microwave in the cabinet. The hard part was getting it out of the cabinet. Once out, removing the cover and replacing the bulb and fuse was very easy. You need the tamper proof star bits to take out the screws holding the cover to the microwave. I got the bit set from Amazon for about $8. My fuse was OK. But I replaced it anyway, since it was 4-year-old. I am no expert in appliance repair, but found it fairly easy to do the repair. After unplugging the microwave, wait for 20 to 30 minutes before opening it, so that the capacitor inside completely discharges. It is supposed to discharge in 30 seconds, but why take a chance of electrocution..?

Took off cover , unpluged switches , took off switch assy, off/on test hooped and howlered for about 5 mins .Then laughed about other sites said could get those switches. Just wanted to say I LOVE Partselect. Super fast del , great price. JUST AWSOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Removed cover, diagnosed problem, ordered part from Parts Select, received part in 2 days, replaced part, tested and replaced oven into built in space.

I pulled out the unit and found 2 interlock switches that are depressed when the door closes. After cycling the door open/closed I found that one of the switches occasionally would stay depressed. The repair was easy (after I took off the panels so I could get to the switch) I simply removed 2 screws that attached the interlock switch assemblies to the main unit. Then I popped out the defective switch and popped in the new one. This did indeed fix my problem.
