JE1440BF002 - Instructions

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.

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 .

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.

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!

Eight screws off the bottom exposed the cover plate. Easily found the motor location the looked up the item number and verified data and ordered the part. Replaced the motor, tightened the screws and flipped it upright. Plugged it in and the lights came on. Set a time pushed start and smiled! The eagle had landed!!!!

Overall repair quite simple. Removed screws from the sides and rear of the microwave, then removed cover. Next, removed only the screws to separate the bottom cover. Removed the one screw in the AC Synchronous motor to remove the motor (had to use small screwdriver through a vent slot in the bottom to remove the screw). Unplugged and removed motor. Installation is the reverse of removal. Note: on the back of my appliance were 4 torx screws with a tamperproof pin in the center. I used the rotary tool to grind out the pins so I could use a regular torx bit instead of ordering specialty bits.

After reading reviews that there was no power what so ever and a fuse replacement will solve the problem, I tried it. Replacing the fuse is very easy (and I am not handy at all). All you have to do is remove the microwave cover from the top by removing two screws, slide the cover to the left and pulling the cover off. Then remove the grill in front of you, by removing one or two screws. The fuse is in front of you, use pliers and be firm but gentle. Replacing the fuse is easy but it did not solve my problem.

It was extremely easy. I put the microwave on my table upside down and could see the motor thru the holes in the bottom cover. It appeared as though the outside skin had to be removed to access the motor but after looking at it there is an access panel I did have to cut it loose. Not bolted on. There was a message stamped into the bottom case next to the panel that said to debur after panel is removed. So I cut it loose on 3 sides was able get to the one screw swap the motor and reinstall it in about 5 minutes. It works like new What an easy and quick repair. Thanks

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.

After contacting GE support I realized the only interest they had in helping me was to recommend sending a $$$ technican to diagnose the problem. I decided to go to the Sears Parts select website.to see if others were experiencing the noise me microwave was making. After reading through others posting on the subject I decided to purchase the Synchronous Motor. While waiting for the part to come I decided to lubricate the hub of the spides that rotates the plate with white Lithium grease. After a couple of times utilizing the microwave noise went away so whn the part arrived at me home I put it in a drawer just incase I need it a some future date. Hope that someone else finds this information useful. "The Crafty Dodger in Houston"

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.

bought a fuse but that didn't solve the problem. Guess I need a new microwave

Pried cover off bottom-center of microwave. It seems to be either glued or lightly tack welded. Removed 2 small Phillips screws to remove motor. Disconnected electric feed by hand. Don't let go of electric wire or small screws. They will be hard to retrieve from behind the rest of the metal base. Reverse process to install new motor. Didn't try to put small cover back on.

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.
