72163659301 Kenmore Microwave - Instructions

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.

Ordered the switches from Partselect, arrive in two days. Had trouble removing the plastic connectors from the old switch terminals, one of the plastic protectors broke, but was able to reuse it. It took a little figuring out how to remove the existing switches. Must push in a tab and rotate the switch on a little pin, then remove. Must be careful not to break the plastic tabs holding the switches in place. Replaced all (3) switches at the same time. All in all it was pretty easy.

I found and removed the clip for the door - top on the inside (not easy to find) and then removed the door. Called support who told me to watch you-tube and there were good instructions there. Needed needle nose pliers to hold broken screw and a screw driver that could fit between the metal. Flat head and phillips are required. OH you should try to leave the screw in the hole as getting it back there is a PIA. Took about 20 minutes and I am challenged mechanically. Altogether, not too bad.

Replaced with new covers.

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.

unplug the unit then pull down , lot of screws are on top. open the cover . you could see the parts that need to replace on the right hand side (heavy side). disconnect wires then test the parts that need to replace by a tester to make sure that it's really broke .then unscrew part and replace .

Very easy repair. I popped of the inside plastic door cover with a putty knife, removed screws to old handle, inserted new handle and reinserted screws and plastic cover. It was that simple. The complete job took me under 3 minutes.

Piece of cake. Pryed the cover off of the back of the door with a flat head screwdriver and then screwed in the new handle.

Slipped the screw driver flat tip along the plastic strip near the latch inside of door to pry off the plastic cover to expose the screws holding on the door. Removed 2 screws and replaced handle less than 15 minutes.

Easy as 1-2-3! Removed door from unit (top right hinge has an easy small lock that simply "snaps out" with a standard screwdriver. Placed door face down on table. Removed outer (perimeter) frame with standard screw driver, by plying up. Removed the two screws (to the handle) from the backside of door with a phillips screwdriver. Replaced with the new door handle and repeated the above steps in reverse. Done.

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.

removed old cover to lamp and reinstalled the new one by unscrewing one screw and screwing the new one back in

Called an appliance repair service
