MMV6178AAS - Instructions

Super Easy. I was able to find the part on your website.
The whole process was excellent.

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.

Parts were received. The price was very good, and delivery was quick. Thank you for your prompt service. LJ

Unscrewing the old one out, putting the new one in.

Information provided on the web site by Part Select, were helpful and encouraging to select and buy the part needed to repair the appliance. No doubt, a skilled person having background in the repair of appliances should attend such repair job.

Since others reported similar problems and it was just the fuse we tried that first. That wasn't the problem so we ordered the Door Interlock Switch Kit. Shipping was very fast! Our microwave had 3 switches. My husband asked how to know which one to switch. I read that one person just did process of elimination. Luckily ours worked on the first change out! So happy to have stumbled across this site and not have to buy a whole new microwave.

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.

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.

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

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.

Did have a difficult time getting the old bulb out as it broke off in the socket. We disconnected the microwave to retrieve the broken bulb with a needle nose tweezer and then installed the new bulb in seconds. The plate glass cover was then placed back. Ended up vacuuming the ceramic stovetop due to broken chips of old bulb when being retrieved. Thanks for the prompt arrival of the new bulb. Hope it will last as long as the other bulb of 5 yrs.

I have tried MANY times to get the proper bulb from various hardware stores with varying degrees of success. My bulb seems to burn out often because we happen to have frequent power surges. This past time I was unable to get a bulb at the hardware store which would work at all. The bulb purchased specifically for this appliance, while very expensive INSTALLS PERFECTLY WITH EASE! Well worth the extra money.

Unplugged microwave, unscrewed cover, opened bulb package, without touching bulb and pushed into holder. Plugged in microwave and alas light worked. Screwed lid back in place.

It literally took me longer to unpackage the fuse than to install it. I removed the outer shell by unscrewing the five screws, lifted it off and set it aside. The old fuse was readily visible so I pulled it out and put the new one in its place. I set the shell back on and replaced the screws. I plugged it in and ran it for 30 seconds while still in the shop just to make sure that solved the problem and presto - it worked like a charm. A $20 part saved me from having to purchase a new microwave (sadly, I had to break the news to the wife).

remove 4 screws from top, front louvered panel snaps out. remove 1 screw from top of keypad, keypad pivot's forward and can be removed. There is a white mounting bracket inside left. Remove two screws, one top and one bottom, bracket lifts up and out. 3 sets wires are attached, mark them with masking tape, top, center, bottom and pull out plugs. They can only attach one way. Using a very small screw tip, lift plastic latch from switch, it rotates out and is removed from the pivot pin. reassemble in reverse order after switches are replaced
