KCMS2055SSS - 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.

1. Remove the trim frame off of the front of the cabinet (4 Phillips screws). At this point, take glass plate and turntable frame out of unit. 2. Slightly lift the unit off the cabinet frame (which is attached to the cabinet) so the feet on the microwave allow the unit to clear the frame and then remove microwave from the cabinet. 3. Once slightly removed from the cabinet, unplug the unit before completely removing it from cabinet. 4. Take 2 Phillips screws out of the side panels. 5. Take about 6-7 T20 Star Pin screws out of the back of the panel. (This may require you to purchase this special tip if you don't have it in your toolbox). 6. Slide the microwave cabinet toward the rear of the unit (the front portion clips into the frame ... don't try prying it off because you'll damage the unit). 7. Completely remove the microwave cabinet housing. 8. Be careful not to damage or catch any internal wiring inside the unit while the cover is off. 9. Turn unit on it's back and remove 4-5 Phillips screws holding the bottom cover in place. Remove bottom cover. 10. Now notice that the turntable motor is completely exposed. 11. Remove the wiring harness from the motor (notice which connection clip has the black wire). 12. Remove the one Phillips screw holding the motor to the frame. 13. Clean around the area in case food spills may have gotten into the area. 14. Insert new motor, put Phillips screw back in and attach power connection. 15. From this point on, just reverse steps to re-assemble microwave and put back in cabinet. 16. Test new turntable motor. 17. Enjoy the smile from your wife because she can now use the microwave!

I had previously replaced the turntable motor, which helped for a small while. When the problem occurred again I examined the turntable assembly (small wheels which support the glass tray as it turns). The wheels were all flat on two sides. It may have been a defect from the beginning or a result of our placing food off-center because this model has a terrible cold spot in the middle of the microwave pattern................ The repair was as simple as taking out the glass tray, pulling the assembly (plastic arms with wheels on the end) off, dropping the new assembly on, and replacing the glass tray.............. This is surely worth a first look before replacing the turntable motor.

I removed the outer cover of the microwave and removed the bottom palte to access the small motor. i unplugged the old motor from teh wiring connector, removed (1) screw and motor came out. I reversed the proceedure with the new motor and it was finished.It was a piece of cake.

removed microwave cover screws, unplugged motor, screwed on new one

I ordered the part from partselect (PS972837 Door Latch Bracket) and read all the instructions written here, very easy to do! Saves me a lot of money!

The tip on the end of the latch broke off, so I had to carefully pry it back in without breaking the new piece. Took a few tries, but got it.

All the electrics worked on Amana microwave EXCEPT for the cooking function. Inspected the control board and found the upper switch on the door interlock was burnt. Installed new switch in minutes and everything now works fine. Unfortunately, had to purchase expensive two switch "kit" although only one switch was kaput. PartsSelect mailing was SUPER fast. Thanks for looking, Scott

1.ordered the part 2.during wait time for part,i epoxied the broken ear of the door latch bracket back on to the broken part.3.waited 24 hours for epoxy to set,4.installed the repaired part.5.reassembled the microwave and reinstalled in the wall unit.6.days passed and the ordered door latch bracket finally arrived.7.we are using the microwave daily with the repaired door latch bracket,but we will keep the new part in reserve,just in case!JUST CAN NOT DO WITHOUT OUR MICROWAVE!

My wife was pushing a few buttons with her knuckle (hands were full)and the microwave just turned off. Just like we had blown a breaker. First I unpluged it. Then I removed the phillips screws of the front panel, and found and removed the ceramic fuse. 3 days later I received the new fuse in the mail, and put it in. I plugged the microwave back in and it works great.

Pried cover off bottom-center of microwave. It seems to be either glued or lightly tack welded. Removed 2 small Phillips screws to remove motor. Disconnected electric feed by hand. Don't let go of electric wire or small screws. They will be hard to retrieve from behind the rest of the metal base. Reverse process to install new motor. Didn't try to put small cover back on.

Took off the outside metal cover determined what the problem was immediately saw the broken latch ordered the new one received in 2 days snapped it into place the door opened then replaced the outside metal cover good as new.

hardest part was taking the microwave down off of the wall to gain access to the diode. Thought if was the transformer but ended up being just a blown diode. remove and replace and bench test. that part took 15 minutes . moral of the story don't boil water under the side of the microwave that holds the electric components.

Overall repair quite simple. Removed screws from the sides and rear of the microwave, then removed cover. Next, removed only the screws to separate the bottom cover. Removed the one screw in the AC Synchronous motor to remove the motor (had to use small screwdriver through a vent slot in the bottom to remove the screw). Unplugged and removed motor. Installation is the reverse of removal. Note: on the back of my appliance were 4 torx screws with a tamperproof pin in the center. I used the rotary tool to grind out the pins so I could use a regular torx bit instead of ordering specialty bits.

Removed base and side screws as needed then unclipped the power lead from the motor. Then removed 2 screws that attach motor to microwave base. Attached new motor then reattached leads and replaced the removed side and base screw.
