ACM1460AC (PACM1460AC0) Amana Microwave - Instructions

Replaced the broken piece with the one purchased at Partselect.com. I was concerned that the part would not be correct since all we did was enter the model number of the microwave. PartSelect.com was really easy to use and sent the correct part. Thanks so much for making this process easy.

removed a dozen screws-discarded large cap-replaced diode-replaced a dozen screws(took longer to replace them than remove for some unknown reason). Microwave now works(wife happy).

I had to unmount the over-the-range microwave oven to be able to gain access to the interior of the oven. Complicating removal (and re-installation) was the fact that there is a "pot-filler" faucet installed directly underneath the oven. In retrospect, I should've removed the faucet before doing the repair, but "c'est la vie."

After I got the microwave down, removing the case was also "interesting." I get bonus points for the fact that the previous owner must've had to replace the same diode before - and then re-assembled the microwave case incorrectly - thereby adding to the confusion (BTW, the service manual that I found online said nothing about how to remove the oven's case).

To remove the case, undo all the screws holding it on, and then rotate the case upwards from the back while also pulling the case backwards. There are crimped folds on the inside of the case that mate with the back edges of the front of the oven's chassis, and these folds have to be unclipped from the chassis in order to remove the case.

Replacing the diode itself was the easiest part of the job. The two connectors on the diode are of different types, making it impossible to install the diode with the wrong polarity.

BTW, the diode that had failed was not an OEM diode; I suspect it was a generic component that had been installed by a repairman sometime between 2004-2008 (when our home's original owners still owned the home). On the other hand, the new diode from PartSelect is an OEM part (it came packaged in a sealed Whirlpool bag).

The fact that the oven had stopped heating indicated that it was either the high-voltage diode or the magnetron that had failed. Since a replacement diode costs ~ 1/10th as much as a replacement magnetron, I figured it made sense to replace the cheaper part first. Fortunately, this fixed the problem.

One last thing: I tried testing both the old and new diodes for conductivity and polarity using my volt-ohm meter (VOM), but I was unable to get either diode to "turn on," even though my VOM is powered by a 9-v battery, and I used the 2-Mohm range setting. I guess the test voltage of my el-cheapo VOM isn't high enough to exceed the diode's threshold voltage, (even though I have successfully used this same VOM to test low-voltage diodes).

Watched a you tube video prior to installing new switch. Followed the video which gave me confidence i was up to the task. After removing the touch pad I found my design was not exactly like the you tube model but I found the defective switch, replaced it and put the microwave back together. Works great. Again watch the videos

Removed the broken plastic base that the glass turntable sets on and put in the new plastic base. Took 5 seconds max! The part arrived in about 24 hours! Great service!

Put in the new part, took less than a minute...

Remove from cabinetry, take cover off and had a very difficult time removing the plastic form that has the switched in. Replace the lowest of all the switches, and then again very difficult time getting the plastic form back in. Some of the plastic even broke during the process but not any that could prevent it from working as it did before. I had ordered a fuse, 2 packs of 2 switches as there are 3 switches but only had to use 1 to get it working again. Tested after switch install, put the cover back on and reinstalled in the cabinet.

Replaced turntable support with new unit.

replace old part with one one ordered from PartSelect

Easy! Just place it in the slot inside the microwave.Finished! Tah Dah!

Just place it in the slot. . . . . 5 Seconds,,,no problem

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).

The turntable wouldn't rotate any more. The problem was the plastic roller guide (under the turntable glass) had cracked where it attached to the shaft. I installed the new part, it fit perfectly, now works great!

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

Opened the package and inserted the turntable roller guide. It was the right one and worked immediately!
