JE1440BF002 - Instructions

With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

unplugged power

located part WB24X10047 and replaced

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.

Used a Motor cycle Jack to remove both unites combined. Removed side panels exposing internal working parts. Removed nonworking Magnetron and replaced it with new Magnetron. The process was completed in about 1 hour.

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

Went on Youtube and pulled up how to fix a microwave.

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

I assumed light was burned out and got a replacement bulb.
Removed back and side screws with slight difficulity.
Was not able to remove cover. The top front would not loosen. I tried every trick in my 80 year repertoire. I gave up and put it back together.
I emailed PartSelect last week explaining the problem. So far no reply.
I am sure I have the right model # and others seem to have little trouble removing the cover.
I paid $85 + tax for the oven and it has worked well for about 8(?) years.
From what I read here, I figured I could handle the bulb replacement.
I'm just out the cost of the bulb and shipping and the oven still works. It would have been nice to have the light work again but we will just wait until it quits working and buy another inexpensive unit.

Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.

Cut the wire connection of access door on the bottom of the oven. Once access door was removed, I took the screw holding the drive motor in place, removed the wire connector and taped the connection to oven so that it did not drop into the bottom of the oven pulled motor out. Put new motor in, put connector back on motor secured the motor with the scre, put access door back in place put roller guide on the drive motor from inside of the oven and put plate on roller and turned it on for a test. it worked.

Replace the fuses

Take off cover then the bottom. Transformer is on the bottom plate and wires won't let it come all the way off, too many wires to pull off so will have to position the bottom plate so you can get to the motor. Remove 1 screw on motor and remove motor. Install new motor connect wires replace bottom plate, replace cover. All done (hope & pray it works ok) mine worked perfect. Hope this helps.

I UNPLUGGED the microwave and removed the cover, using a phillips and a Torx screwdriver for the machine screws. I set these screws aside, so as not to confuse them with the later encountered screws. I photographed the magnetron to assure proper placement of the 6 phillips machine screws involved in reassembly (marking the the locations on the old magnetron would do as well. I marked the old magnetron "old", to avoid later confusion. I removed the two screws holding the shields to the magnetron. I removed 3 of the 4 screws holding the magnetron to the microwave, leaving one of the top screws. I held the magnetron securely and removed the last screw, pulling out a the part of the magnetron that penetrated the microwave. I installed the new magnetron in reverse order. One problem I encountered was locating one of the six screws, which had been pulled into the old magnetron by magnetism.

AFter I put the roller guide and glass cooking tray inside the microwave it still didn't spin. After check with the video, I was warned not to try to replace the motor which spins the tray, that there was a chance of electrical shock. I took the oven to my repair place and they made the repairs.

Replaced the fuse. Result; did not fix the problem.
