JE1440BF002 - Instructions

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.

i unplugged the unit,unscrewed the outer shell so that all the wiring and internal components were visible.starting at the first of three micro switches i removed the slip on terminals installed the alligator clips too the wires so the switch would now be bypassed.i made sure the wires and clips were not touching anything plugged unit in and it worked.i then installed the new switch and closed up the outer shell

Easy, and the microwave still doesn't work.

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

Unplug.Take off the external cowling from the back of the unit by removing the torx security screws. Tip: instead use a thin screwdriver blade to unscrew the torx screws, or knock out the center pins of these screws. Remove the bottom panel. The replacement motor is attached with one phillips screw, re-attach wires to motor - polarity doesn't matter. Re-assemble and you're finished.

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.

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.

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.

First I took out the screws holding the sides and back to the microwave. I discovered that the rotissereie motor was also damaged, but had an old GE microwave that had quit working-took out motor from other GE(motor was the same), installed motor in microwave, lined up pin to roller assy. and that was it!

Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ordered the switches from Partselect, arrive in two days. Had trouble removing the plastic connectors from the old switch terminals, one of the plastic protectors broke, but was able to reuse it. It took a little figuring out how to remove the existing switches. Must push in a tab and rotate the switch on a little pin, then remove. Must be careful not to break the plastic tabs holding the switches in place. Replaced all (3) switches at the same time. All in all it was pretty easy.

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..?
