GC900QPPQ1 Whirlpool Trash Compactor - Instructions

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.

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.
