Moved the compactor out from under cabinet and unplugged the powercable.Laid compactor over on its side Removed the top (4 screws) and base plate (3 screws) as well as the coverplate for the motor(3 screws)Found that large drive was broken in half. Used two screwdrivers to start split ring then pliers to pull it off the rest of the way.
Removed the drive gear and the washer.
Used a nail to drive out the pin for the smaller drive gear kit. Removed and replaced with new, used new pin to lock it on to the shaft. Changed out the bearings and washers on one powerscrew, put chain back on. Then was then a simple matter to put the new gear back on the chain then slide the whole thing back on the drive shaft. Replace the washer then slip the split ring back in place and seat it home with the pliers. Greased chain, gear drive and powerscrew. Put all covers back on with the screws. Pushed button it worked.

Trash Compactor ram wouldn't lower

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.

Compactor motor kept running after cycle ran, making alot of noise and unit jumping around.

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.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

Replaced the gear and unit worked execpt the plunger hit the side of the garbage container. This appears the be the reason the gear broke in the first place. Defective assembly from the factory.

To correct I had to remove the newly installed gear system remove inside cardboard side cover, Remove the screws that hold the bearing for the lift screw so I could remove the chain. After removing the chain I could adjust the plunger to be level and not hit the side of the garbage container on its way down.

After calling a repair man and being told my appliance was to old for him to repair I discovered your website. I simply entered the model number and a picture of the part I was looking for was easily found. I ordered online and received the replacement parts 5 day's later. I simply swapped out the old locking nuts with the new ones from your website and the repair was complete. What could have been an easy $100 repair cost a fraction of that and the trash compactor is working just fine.

Broken Gear

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.

The compactor keeps on making noise at the end of the compactor cycle with shaking until the "off" switch is pushed.

Took off front panel and replaced the directional switch which I thought was the problem. However, the problem continued. I read on line it could be the "centrifugal" switch on top of the motor. I haven't gotten around to taking it apart yet to see if that is the problem because it is more involved down under and in the back. That switch cost $88.
Any suggestions from others?

I removed the plastic portion to get to the switch and wires. I removed the old switch by disconnecting the two wires and pushing it out of its setting.

I discovered the old switch only had 2 prongs where the new switch had 3. Once I figured which 2 of the 3 prongs would light the lightbulb,
I then connected the two wires to the correct prongs of the new switch. I pushed the new switch into its setting and replaced the plastic portion on the refrigerator. Voila, success. The refrigerator door now comes on when its door is opened.

Thanks for the having the part and getting it at our door step in 3 days.
