LMV1680ST LG - Instructions

I unplugged the microwave. I did watch a YouTube video to see how the plastic frame around the door could be removed. I used a putty knife to pry it off. The spring was still in good shape, so I hooked it up to the new latch/locker part and onto the microwave. This was just a little time consuming because I was trying to be careful so I wouldn't break anything on the new part. The plastic frame clicked right back on. I plugged the microwave in and it worked right away. If I can do it, you can do it. Sure beat buying a new microwave. Great experience.

I removed the bottom plate which had 9 screws.
than unplug 2 wires to the motor and unscrewed 2 screws, replaced the old motor with the new one and also the coupler. and so far no noise. easy fix. Thanks

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

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 the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

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.

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!

Removed outer cover

removed lower door switch

installed new switch

Wa La!

I went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.

Removed some cosmetic panels. Removed the assembly with micro switches. Examined the faulty switch by checking the clicking action of switch. Two others were ok by this method. Replaced the switch with new one. Works fine so far. Thanks to web site and YouTube videos.

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.

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.

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!

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
