ACO18 - Instructions

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.

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 .

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 ... Read more 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.

I UNPLUGGED the microwave and removed the cover, using a phillips and a Torx screwdriver for the machine screws. I set these screws aside, so as not to confuse them with the later encountered screws. I photographed the magnetron to assure proper placement of the 6 phillips machine screws involved in reassembly (marking the the locations ... Read more on the old magnetron would do as well. I marked the old magnetron "old", to avoid later confusion. I removed the two screws holding the shields to the magnetron. I removed 3 of the 4 screws holding the magnetron to the microwave, leaving one of the top screws. I held the magnetron securely and removed the last screw, pulling out a the part of the magnetron that penetrated the microwave. I installed the new magnetron in reverse order. One problem I encountered was locating one of the six screws, which had been pulled into the old magnetron by magnetism.

very simple

After reading on-line about other Amana microwaves, that said the arching was probablly due to dirt or grease & I knew it wasn't dirty, I decided to try the sandpaper recommended to clean the carbon from the wall where the shelf holder had burned several years ago. This caused the remainder of the clip to become loose. I then took a sha ... Read more rp knife & popped the clip out which left a neat square hole which your shelf holder popped right into. The filters were an afterthought because I didn't want to pay shipping for only a $2 item

You had alerted that it was imperative to unplug unit before starting to remove defective bulb. As described, there was silicon on bulb and socket and bulb broke upon my attempt to remove. Had to use needle nose pliers to get metal base of old bulb from socket, then all went well.

Removed the old part by extracting the two screws. Removed the broken tabs from under the screw holes. Replaced with new part. The part was new so it naturally was whiter that the old one. Thats ok!

Lifted up the glass plate and stuck the assembly under it ;)

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.

First let me say that I tried several places to get what I thought was a simple light bulb. This included several national hardware stores as well as a national electrical supply company. No luck. Went to the manual and PartSelect. Not only did you have it in stock, ship right away,at a reasonable price it arrived in a matter of days. One ... Read more would not normally think of receiving a "how to" video to change a light bulb but you did. That impressed me. Suffice to say the replacement went well and you can be certain the next time I need a part I will go to you first. I am also impressed with the organizations with which you are affiliated with. BBB, Norton, PayPal, money back guarantee etc. Thank You The entire process was made pleasant with your support.
