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 ... Read more 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.

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 ... Read more 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.

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 r ... Read more emoved 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.

I tested the motor with an OHM meter, saw it was shot. Broke the turntable off when I tried to take it out from inside where it's attatched to the drive motor.( The plastic was like glued or welded onto the shaft of the original motor ) Had to open up the removable trap door on the bottom to pull the one screw that holds the motor in.

saved me having to buy a new microwave. It was super fast delivery, had the part the next day! Amazing service and great customer support.

I looked up the part number, with shipping it came to $16, and in one minute of installation time, I just gently pushed the button into the front using the original springs that pushed the button back out, and it just clicked into place, the microwave back in action.

Inserted spring on middle post on button back side. Pushed button/spring into hole on front of microwave until clips engaged and snaped into place.

Lifted up the glass plate, lifted out the plastic base that rotates and placed the new one inside. The piece that connects is shaped like a semi-circle, so I rotated it until is dropped into place. Then I put back the glass plate and it was finished.

brought new one and the help with the sites pictures to describe what I need was extremely helpful. The prompt delivery was great.

Replaced Microwave Button with new button and hooks. Repaire took one min. by just pushing the new button on the Microwave and it hooked on and did not pop out. Good for another 4 years maybe!
