AMB7554 Whirlpool Trash Compactor - Instructions

Replaced the limit switch. This did not alter the problem. Took off the On/Off/Start switch and dissasembled. I found the the Start switch was stuck in the on position. I reassembled the switch mechanism assuring that the Red "ON" indicator moldings were correctly positioned and reassembled everything. The Compactor now works properly. Need to add "Check the Start switch" to diagnosis.

Followed PartsSelect instructions, the Compactor was appoximately $1000. when I purchased it. The kit was $26.14. I will forever be a customer of this company. Thank you, Brian

replaced the large gear and put it back together.

Took out old gears replaced with new very easy with your dirictions.

The repair was a breeze, a piece of cake, a walk in the park, a day at the beach. The part arrived quickly and installation was fast and simple. A week earlier I had the misfortune of ordering these parts from another supplier. One of the parts obviously was not correct, so I called customer service. Although the operator was polite, she insisted that the part I received was the right one (even though it was 2 inches too narrow). I looked up the part at PartSelect.com and ordered it. It arrived the following day, and fit perfectly. Thanks, PartSelect.com.

Same problem as described previously on this site. Pulled unit out and replaced the gear as described. Thanks for the info - would have been tough with out it.

Very simple, changed the gear, adjusted the drive and tested. Very straight forward.

Laid appliance on side - removed top sheet metal cover and bottom sheet metal cover. Broken delrin ring gear was on bottom of bottom cover (housing). Gear had broken off of its hub, which also was the sprocket chain drive for both acme screws driving the compactor platten. Motor had to be loosened so that the chain could be removed from the old sprocket hub, and the new delrin ring gear - with new sprocket hub attached - could be mounted on its fixed spindle. With new delrin gear/chain sprocket mounted, the motor had to be spaced and tightened to allow 0.010 inch lash between the gears. The only instructions included with the new gear was how to do this - by placing a piece of paper in between the pinion gear on the motor, and the new ring gear, and then tightening the motor into place. This was done, the sheet metal covers were re-installed, and the compactor works just fine. There is a design flaw in the original (KitchenAid) engineering of the gear, however, and I expect that in the next four years this will probably happen again.

Thanks to Parts Select and their detailed instructions it turn out great! Replacement Parts fit Great!

First off....I was surprised at how inexpensive the drive gear kit was. As others commented, they fit perfectly and I believe will fit other manufacturer's models since there is a lot of cross branding. The Drive gear replacement itself would be easy as described by others so I won't repeat that. However replacing the plastic tubular "ram stops" on the screw drive was a challenge since there are no "helpful hints" in the blog. To do that you have to work from the top and sides. Needed to remove the two gear cams where the screw drives are seated on the bottom of the unit, then (working with the unit on it's side)you have to raise the whole (heavy) plunger that is attached to the drive screws high enough to remove the old tubular ram stops and bushing and replace. To raise the plunger assembly out from the top you have to remove the sheet metal top plate of the unit....and....importantly remove the control panel on the front where the switches are. There is a limiter switch that has a metal arm which engages a plate on the plunger to stop the unit when it reaches the top. You need to remove that switch to be able to raise the plunger assembly high enough to get the new parts on the screw drive. Put all that back together and then go on to the gear replacement as described by others which was straight forward. Very messy job with all the grease and garbage residue. I am pretty handy figuring these things out, and there may be an easier way, but next time I will call a pro or replace the whole compactor.

changed out the big gear that was broken

Replaced drive gears.They arrived in a kit from Parts Select with instructions.They fit perfectly and the compactor works like new.

Had to first raise the screw plate that compacts the garbage. Then had to turn the compactor over and remove screws holding the bottom plate on in order to get to the gears. Once that was done I removed the worn gears and the chain drive and replaced with the new gears and the chain. Put the unit back together and works like a new one. A $35 dollar fix for a unit that sells for around $900 today. Thanks to partslect for being able to help me with the parts needed. Not only did I save on a new unit but by doing this myself I saved around $100 in labor charges.

The part was suppose to come with instructions, but did not. However, it was easy after reading the comments on-line, and discovering that the front cover had to be removed in order to expose the whole switch and wires. I did drop one of the mounting screws down the front of the compactor and was not able to recover it. So, I had to make a trip to the hardware store for a replacement. They couldn't match the remaining screw but I found 2 similar ones with lock washers and nuts that worked just fine. I saved a $90 service charge and probably double the cost of the switch by doing it myself.
