MMV5186AAQ - 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.

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 sharp 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

Replaced with new covers.

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 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.

The door was not engaging the micro switches properly no doubt from 10+ years of wear. The upper switch removed fairly easily but take care not to tweak the plastic brace too much or it will snap. The lower one was the tricky one. After much examination I noticed that the trick to remove it was underneath the brace. Take a butter knife (no joke) and insert it just under the old micro switch and gently press down twisting the micro switch every so slightly til it releases. The replacements snap back in with no trouble. The microwave is working much better now, though not perfect.

I didn't do the repair -- my husband did, said it was easy, had no problems what so ever! The new bulbs give a lot more light to the cooking area.

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.

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 .

It wasn't so much a repair as a replacement. If I had only found PartSelect earlier! I made the huge mistake of ordering a replacement from Sears - since that's where I bought the microwave. The pictures on their website are blurry - it's VERY difficult to tell which plate is the right one. Of course the one I got wouldn't work, so I had to send it back. Except that it didn't come from Sears, it came from a totally different vendor and I have no idea if they will honor the return with a refund, because of 'restocking fees'. Oh well. I found PartSelect, and the rest is all good. Your website is great. I found the right plate immediately - the pictures are clear and you can SEE what you're getting. The turn-around time between ordering online and receipt of the plate was phenomenal! SO QUICK! Thank you, PartSelect for making it so easy for me! Y'all are the BEST!!!! Jerel

Replaced light bulb.

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

removed grill cover, removed bulb plate, unscrew bulb, screw new bulb in socket,put bulb cover back on and screw grill cover back on. no issues whatsoever.

I put in the filter. The "over the stove microwave" made installation so easy even a woman could do it!

The turn table motor stopped turning ,but we never turned the off button off on the microwave and kept using it ,so it shorted to the outlet neutral (white) wire at the circuit breaker fuse panel , the wire burnt off. I cut the wire re-installed it in a good buss connector.That restored power back to the outlet.** So now to replace bad Turn-Motor: Using phillip screw driver remove (bottom)filter/light panel- 10 screws, unplug lights and motor connectors, lower panel out of the way ,remove 2 screws from motor and replace motor. Install in reverse order. (Fast Fix)**Note:If you had other problems like I did consult with a professional electrician.
