ACO1840AW - Instructions

Unscrewed glass panel, removed old bulb, cleaned glass panel and installed new bulb. Screwed panel back into place.

I was able to find the part on line and within a few days received the part and installed it with no problems thanks to the website drawing information.

It was not the magnitude of the repair but the fact I ordered the part on a thursday and it was delivered on saturday. Timing ws very important, especially this time of year.

using the measurements shown in parts catalog, it appeared the item I needed was correct for what I ordered.

Easy, and the microwave still doesn't work.

Philips screwdriver
Removed screw (1)
Removed light bulb
Put in new light bulb
Closed door to bulb compartment
Returned screw.

Pro tip! Check how many bulbs you need before ordering. Mine only needed two. I got two. I suspect I’ll buy a new microwave before new bulb burns out again. Ordering/delivery was fast. No need to have spare on hand.

Removed one screw lowered glass cover removed burned out bulb replaced with new one put glass back reinstalled screw. Dune 5 minutes back in business

replaced plate

remove the part from the box and wipe it down with warm soapy water, rinse and dry and place in microwave.

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 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.

Removed door from microwave and then popped the inside widow trim ring off. Removed 4 screws from the window bracket, replaced the latch with a new part and then assembled.

very simple

Open compartment, installed bulb, closed compartment

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

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.
