72180039700 Kenmore Microwave - Instructions

Easy, and the microwave still doesn't work.

Removed door from microwave and then popped the inside widow trim ring off. Removed 4 screws from the window bracket, replaced the latch with a new part and then assembled.

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.

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.

very simple

Problem was a faulty door latch switch. I easily accessed the switch by removing the control panel, total of 4 screws. After that, just disconnected the three switch door latch assembly and connected the new one. Took about half an hour and was very easy. Unit works perfectly now.

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!!

remove the screws from the bottom, leave tthe light wires attached. There are two screws holding the motor on, disconnect and mark the old unit where the yellow wire goes. Mount motor with two screws and connect wires. Turn on Miicrowave for 10 sec, to be sure all is correct. Attacch bottom cover and reattach power cord. Before doing anything make sure power cord is disconnected and reattached when sealed.

1. Removed unit from the cabinet. (2 screws). 2. Remove the outer microwave metal shell. (10 screws). 3. Locate and remove part. (3 screws). 4. Install new part and replace all screws. 5. Install unit back into cabinet. So easy. I will share this site with all of my friends.

First, I checked YouTube to see if there was a video showing how to do the repair ... It's as easy as unplugging the power cord, removing 6-8 screws on the bottom panel, unplugging the wire harness from the AC synchronous motor, removing two screws hold the motor in place, putting the new motor in place with the two screws, connect the two wires to the brass tabs, replacing the bottom panel, reconnecting the power - and you're done. Easy!

Disconnect power. Remove 4 Philips screws from top of valance. remove valance. Remove 1 screw from top of touch pad panel. Remove 1 screw from bottom of touch pad panel. Lift panel slightly and pull out. disconnect wire plugs. Place panel on table . remove 3 screws from PCB. CAREFULLY lift ribbon cable lock and remove ribbon cable. CAREFULLY release PCB latch and lift up and out. Install new PCB in reverse order. CAREFULLY slip ribbon cable in slot and press lock. replace all plugs, screws and panels in reverse order. Reconnect power and test.

I unscrewed the light cover, removed the burned out light bulb and replaced it with one I ordered on Partselect.com. It was very easy.

Very easy to replace just one screw on the top of the vent, if changing your grille vent change out the grease filter and charcoal filter at same time clean both area's of grease if your microwave is above your stove.
