85419 LG Microwave - Instructions

Used putty knife to unsnap tabs to separate inner trim on top, bottom and handle sides (left the hinge side attached), removed upper and lower screws, replaced handle, reinserted screws (tight fit, big fingers, several dropped screws, one under the stove = 15+ minutes), re-snapped trim

Not knowing which of the switches to replace I ordered all three in the assembly. Replacing the full assembly was easy, first unplug the microwave. Then remove the top cover to access the screws that hold the control panel in place and let the control panel hang. There are two screws that hold the assembly in place - remove those. I used needle nose pliers to pull the wires off of the switches and immediately put the wires on to the new assembly so there was no confusion on what wire went where. Place the assembly back in position, replace the two screws to hold it in, put control panel in place and secure screws. Replace top cover and plug in.

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

Removed outer cover

removed lower door switch

installed new switch

Wa La!

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.

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.

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!

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

Used plastic putty knife to separate inside door plastic molding from metal door frame. Small section at a time starting from latch area. Worked the knife around door to separate plastic molding. Leave plastic intact near door hinges. Carefully separate out of the way the molding, and access Phillip screws with long screw driver. Replace handle and screw tight the screws. Push into place the plastic molding with your fingers until it clips back into place. The end.

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

Pried off the inner molding around the door to access screws. Attached new handle. reattached molding. Very easy

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!
