PER YOUR INSTRUCTION

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.

Easy, and the microwave still doesn't work.

The Halogen Light Bulbs for lighting the area below the microwave seemed to be burned out. I order new bulbs but by the time they arrived the old bulbs appeared to be working again. Not sure why this happened but I have new bulbs if they become burned out for good at some point.

Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.

Ridiculously easy, unscrew, and change bulbs. Having the correct bulbs made all the difference, I did not have to waste time looking for the correct one.

Removed old bulbs replaced with new. Bulb fit perfect thank you

Removed screw holding faceplate that covered bulbs. Next inserted new bulbs into sockets.
Turned on surface light to insure they worked - they did. Re-attached faceplate.

Replace the fuses

It was just a matter of removing the old bulb and easily putting the new one in place. Very simple repair and the bulb was received amazingly fast. Was no doubt the best service I have received and I appreciate the quick response.

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 .

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.
