Trash compactor started making "bumping" sounds when the RAM went through a cycle and tried to come back up. Finally, one day heard a "pop" went the RAM traveled to the bottom. The gear broke in half. Purchased the gear parts "KIT" online and repair took 15 minutes. Easy to do. Unfortunately, this was not only problem. The "cause" of the gear breaking was the Momentary Start/Stop Switch was bad. It's failure led to the main switch not working. The unit could not tell when the RAM had reached the top of it's cycle. The other problem was that I didn't put trash in the compactor. Suggest HIGHLY to never operate the unit's RAM mechanism without the compactor being at least 1/2 full per the instruction manual. Running it empty can cause a major problem, such as the gear breaking/stripping.

Pulled compactor out on a piece of cardboard. Used socket set to take top off and evaluate the problem. Power nut was not holding on one side. We ordered two power nuts. Decided to repair only the unlevel side. Fast and easy and cheaper than a new compactor. Whirlpool compactor is 28 years old and working like a charm. Thanks for the diagram and accessibility to parts.

Moved the compactor out from under cabinet, laid it on it's side, removed bottom casing (two nuts front, three back), remove compression pin from small drive gear shart, replace new small drive gear and install compression pin, loosen motor mounts to allow large gear replacement, remove circlip holding large drive gear to shaft, remove and repace damaged gear, set gear clearance and tighten motor mounts, grease gears, replace bottom casing. .
