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.

Inside "cavity" bulb was a PITA. Need to remove top decorative trim (2 screws and tabs) to access bulb housing. Broke 1 screw tab so be careful (Wiggle it more). Acccess to bulb housing was made for younger smaller hands, attached by 1 screw. Remove screw, rotate housing, replace bulb. Reverse proceedure. Outside bulb, cake...1 screw, drop lens replace bulb, your done.

Removed the glass shield and inserted the 2 bulbs. Then replaced the glass shield.

The staff were terrific. Thanks so much as it had a happy ending.

Used a phillips screwdriver to remove the screw holding the light cover in place. Removed the two bulbs and replaced them. Closed the cover and tightened the screw

took glass cover off being an electrician and saw lamp or bulb was burned out. googled your site and with model number.went on partselect found lamp,orderd it.2 days later lamp arived installed lamp. So easy no running around or making several calls

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.

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

Screw out-old bulb out- new bulb in- screw back in!!!!!

unscrew one screw and remove bulb and insert new bulb and replace lense with one screw-

as easy as it gets-

Repair was simple; only a phillips head screw driver was required to remove the access plate.

Part Select delivered the replacement lamps within 3 days from the date I placed the order - great service.

Unscrew (one screw) and take off the cover of the surface light under the microwave (the light over the stove). Firmly pull out the old light bulbs. Align the two prongs of the new bulbs into the socket and firmly push into the recepticle. Replace the cover and screw.

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

Opened the cover. Removed burned out bulbs. Ordered replacements which arrived fairly quickly. Forgot to turn off power to unit (didn't matter in the end!). Using the bubble wrap the new bulbs came in, I inserted the bulbs one by one into their respective sockets. Not really tricky but the surface light is in the back of the microwave so I had to lean over the stove to get all the way back. Once in the bulbs worked fine. Closed the cover. All back to normal.

My daughter hand installed bulbs without a problem, took a minute and used a phillips to reinstall the cover. I shopped on-line because I wasted two hours between Lowe's and Home Depot trying to get the right bulb. I did think your postage was crazy high, otherwise glad to get the right bulbs to solve the problem.
