JVM1540DMBB (CBKEGEU) LG Range - Instructions

The original cover was burned and actually caught on fire. Research informed me that food can splatter and stick to the cover. The particle will get hot enough to ignite the plastic cover. I ordered the cover and included the fan since it was so cheap, Replacement was super easy. Done in 10 minutes and made my wife happy. She was ready to buy a new microwave because she thought something was wrong with ours but food splatter was the cause. Parts were less than $10 + $6 shipping. Keep the inside of the microwave clean!!

new glass tray

Just removed and replaced by putting the new turntable and glass in, 1, 2, 3; that's it. I'm so thankful for this site because I would have had to buy a whole new microwave. Thanks a million!

Unplugged the microwave. I opened the door. I used a butter knife to pop the bezel off the inside of the door. I pushed the locker up and to the left and used the butter knife to pry it loose. Disconnected the locker from the spring, and reversed for the installation.

removed filters (2) beneath microwave, took turntable glass dish and roller track out of microwave, pulled up on turntable drive triangle peg to disconnect it from drive motor under the microwave. Removed 7 Philips head screws that hold the light assembly and filters in place, then lowered the assembly plate down to expose the wire harnesses for the drive motor and the lights. Disconnected the wire harness plug fron the motor and unscrewed two screws holding the motor in place.
Assembly is the reverse of disassembly.

removed old cover put the new one in place found right size screw from my tool box, tightened it.

Change gasket

Needed to raise the part to match the ring. I used peanut butter to hold plastic shim while replacing to hold it in place. Built in Oct. 2009.

Originally called it "grease filter" until I found very small print "air filter" on damaged original. Part #PS3527528

Removed door from microwave and then popped the inside widow trim ring off. Removed 4 screws from the window bracket, replaced the latch with a new part and then assembled.

Wanted to see the instructions before I install 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.
