MV1645AGTL (CSBELGA) LG Microwave - Instructions

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

Take cover off microwave. Check door switches to determine which one was faulty.Remove and replace faulty switch.

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.

Change gasket

Used fingers to pull damaged cover away from microwave interior body. Used fingers to snap replacement cover into open slots.

Cover snap right into special slots.

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

Slipped into place with ease -- right bottom of microwave

removed power cord replace turntable motor by lowering bottom panel removing two screws holding the motor on and two wires and reinstalled

Both were easy to replace. I followed the instructions in the users manual which came with the microwave. On the grease filter, I removed the 2 Phillips head screws which hold the grill plate in place. I had to open the microwave all the way to remove the grill plate. The grease filter was easy to remove and replace with a new one. I then put the grill back in and secured it with the 2 screws. Easy Peasy!

i unplugged the unit,unscrewed the outer shell so that all the wiring and internal components were visible.starting at the first of three micro switches i removed the slip on terminals installed the alligator clips too the wires so the switch would now be bypassed.i made sure the wires and clips were not touching anything plugged unit in and it worked.i then installed the new switch and closed up the outer shell

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.

Wanted to see the instructions before I install it.

Pop old one out and replaced it with new one.

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.

Received my replacement Tray,Glass in only 2 days. Opened it and placed it in the Microwave. Yep, it was that easy!

removed screws from bottom of microwave... lowered bottom plate.. unplugged motor and replaced with new motor/AC synchronous. Reinstalled bottom plate......... DONE!!
