I pulled the trash compactor out from under the counter.
I took out the four screws that kept the top cover in place to expose the ram.
The gear shafts were turning but the ram would not lower, at first I though the ram drive bolts were stripped and it wouldn't engage the shaft. Then I realized there was a mechanical directional\limit switch at the top that controlled the power and direction the gear shafts were turning, this switch was broken.
Just had to take off the front plate that was held on by a number of screws and replace the switch that was held on by two more screws. It had five wires attached to it, the new switch was clearly labeled as to which color wire went where.
Pulled the Compactor from underneath cabinet, unplugged power. Removed the top plate off compactor to expose the crush piston. Removed the front control panel by removing two phillips screws, wiring and directional (limit) switch is now exposed. Removed the two screws securing switch, removed wiring one wire at a time and replaced on new switch in same position. Replaced switch in same manner as removed, and followed reverse of above to re-assemble. Plugged back in and tested, problem resolved works like new. Only took possibly 30" to repair and saved an expensive service call.
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.
