72180599200 Kenmore Microwave - Instructions

Separated the two elements on the front door. Then inserted the new handle and reconnected the front door. It was an easy 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.

Removed outer cover

removed lower door switch

installed new switch

Wa La!

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.

Open the microwave door.
On the interior of the door, there is a plastic molding around the locks and most outer part of the door. Pop that with a flathead screwdriver or butter knife. You’ll immediately see two screw heads. Screw counterclockwise to release the fragments of the old handle. DO NOT THROW THOSE SCREWS AWAY. Reattach new handle using the same screws. Pop the piece of plastic molding back in and you’re done.

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.

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.

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.

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.

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

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