Go onto youtube, such as https://www.youtube.com/watch?v=-ITkrwhDNMQ and watch similar videos for DYI. The process is very similar to other models.
Once the door is removed, place oven door on a towel or soft place so it does not scratch the door. Unscrew the screws and make sure you notice where each screw goes, so you know the process of where each screw goes when you re-assemble.
Once the inner cover is removed, remove the insulation, too so you don't damage it. Use Wet/Dry Shop Vac to clean the shattered glass. (WORD OF ADVICE: I did not remove the insulation and the suction of the Shop Vac removed part of the insulation, so now instead of a quick turn around repair turns into a few weeks repair, because the insulation is on back order 10-14 days from the supplier. DON"T MAKE THE SAME MISTAKE!)
Once the glass has been removed, the new inner glass is replaced, begin by re-assemble the oven door with the correct screws and attached the oven door to the range.
Unplugged oven electric and turned gas off. Removed all back covers from the unit. Removed the cover on the inside covering the burner and fan in the back of the convection oven. Removed the nut securing the fan to motor shaft with helper holding the motor. Removed the three electrical wires attached to motor, making note where they go. Removed screws mounting the motor to oven. Removed motor cooling fan and shaft spacer from old motor. Fit in same orientation on new motor. Replace all parts in reverse order, restore gas and electric, turn on and test.
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.
