LMV1680ST LG Microwave - Instructions

Read the troubleshooting section on this site. Figured it was an interlock problem because the food was not getting hot (magentron not turning on) and the carousel was not turning. Did not think both the carousel motor and magnetron failed at same time, thus indicated an interlock problem. The interlock switches are actuated by the door latch. Replaced the assembly locker piece with all three switches (only a $20 dollar part) and microwave was fully operational again. Wife and kids think I am a hero.

After checking all three switches for continuity I determined that the plastic door lever had warped or gone out of wack. After shutting off power at the breaker box I removed the door, the inside trim piece around the inside of the glass. Removed the black two prong door lever, reattached the new door lever and then reinstalled the trim piece and all screws. Works fine now. Easy fix just make sure your switches are all ok then replace the door lever.

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.

WORTHLESS...I EMAILED YOU ON 2/7/22 AFTER RECEIVING THE DAMAGED FILTER DUE TO NOT SHIPPING IN A HARD OR SOMETHING IN THE ENVELOPE TO PROTECT THE FILTER FROM BEING BENT.
I HAVE NOT HAD ANY RESPONSE FROM YOU FOR THE DAMAGED FILTER OR WHEN I CAN EXPECT ONE THAT I CAN USE.
UNSATISIFACTORY SERVICE!

Followed owners manual instructions to the letter: removed two top screws, opened the unit door so I could slide out the old filter. We don’t cook much at all in the unit, mostly just heating coffee and reheating leftovers. BUT! The top grill was pretty greasy and needed hot soapy water to clean, including in the depths of the top area. The whole process, especially the company website for part ID and purchase, was slick!

Wanted to see the instructions before I install it.

I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.

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

Slipped into place with ease -- right bottom of microwave

Change gasket

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

Took old ones out, threw away and put new ones in easily.

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!

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.
