ACO1840AW - Instructions

It was great to find the part I needed. I did'nt have a model number because the microwave was in the cabinetry. Yet I was still able to find just what I neede thanks to the photos.No store had it but parts select did. thanks!

I disconnected the power. Took off the front panel that was held together by two screws. Reviewed the schematic that was inside. Located the switches, saw which lead was burnt. Unscrewed the two screws that held the switch in place, cleaned the connector, and put the switch in and connectors back. Powered the device, tested for cooking/heating functionality. It worked, Closed the front panel

Removed case,
Discharged HV capacitor and removed cooling fan.
Unscrewed ground end of HV diode and unplugged from HV capacitor.
Installed new diode by reversing the order. In my case, the problem was the magnetron was bad, so I replaced it as well.

Put s pot under were you take the screw out.If you drop it you can get it easy

I unplugged the microwave. I did watch a YouTube video to see how the plastic frame around the door could be removed. I used a putty knife to pry it off. The spring was still in good shape, so I hooked it up to the new latch/locker part and onto the microwave. This was just a little time consuming because I was trying to be careful so I wouldn't break anything on the new part. The plastic frame clicked right back on. I plugged the microwave in and it worked right away. If I can do it, you can do it. Sure beat buying a new microwave. Great experience.

well I unplugged the microwave one day prior to working on it. shock precaution smart way to do this job. very easy pullout the screws behind the unit pull off the outer casing. minor screws inside the unit you have to remove a couple things out of the way. unplug the magnetron and remove first gives you more room to work on the side panel to replace the micro switches. I only replaced one the bottom micro switch. only one bad, but since I was in there I clean the bulb and changed the magnetron any ways. I read other reviews and made my choice to do so. it works perfectly now. Thanks PartSelect for having parts.

Removed some cosmetic panels. Removed the assembly with micro switches. Examined the faulty switch by checking the clicking action of switch. Two others were ok by this method. Replaced the switch with new one. Works fine so far. Thanks to web site and YouTube videos.

Initially we started looking to buy a replacement microwave to replace our 13+ year old built-in microwave. It was a real pain finding a replacement to fit the exact dimensions. So I thought I'd try to find an old KitchenAid microwave. However, I was pleasantly surprised when this site came up on my search. Their website allows me to input the problems and then it showed two possible parts that needed to be replaced. I emailed tech support and asked them which part I needed. They responded very quickly and said I needed to replace the magnetron. I watched a couple YouTube videos and then pulled my microwave apart. It was incredibly easy to pull the outer cover off. The magnetron had 5 screws that needed to be removed and one electrical plug. Took me maybe 10 min to complete the entire repair. It was one of the easiest repairs I've done and so thankful for this site They saved me a ton of money from not buying a new microwave and we now have our microwave working again. In hindsight, I wouldn't hesitate. I'd order the Part now and get it fixed.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

change light bulbs

Microwave vented up toward the ceiling discoloring it. I positioned the charcoal filter over the vent holding it in place with scotch tape. It keeps the ceiling clean and dose not affect air flow from the exhaust vent. I change the filter every year.

screwed in new bulb

removed old covers which were cracked and dirty.
the repair part looked exactly like the original but did not fit correctly. i had to do some changing of the size to make it fit. it does not clip in place as it should but we are living with it as it does cover the light bulb. the grease filter is perfect
