Ram goes down but does not go back up. Makes a banging noise. Have to then turn it off. Turn back on and goes up. Is there a sensor in the motor that tells it to go back up, or a bottom limit switch, etc. Not sure what part to even check.
Model # kucc151dwh1.
Hi doglaw44
If your trash compactor has the cycle switch with Solid Pack and Normal positions, make sure the switch is in Normal position.
Check the on-off-start switch. After you turn it to Start and release, it should automatically return to On position. If it got stuck in Start position, the motor will try to restart, causing a banging noise.

Here are the break down diagrams for the Kitchen Aid trash compactor Model KUCC151DWH1
Good luck.

Gene,
I have the same problem with my KitchenAid KUCC151T0 compactor. When the ram goes down, the unit fails to sense when the bottom or sufficient trash resistance is reached. The ensuing banging lasts for 5 seconds (unit shuts off) or less if the key is turned off. When the unit comes back (turned back on), the ram retracts normally to the top. This occurs wheter in normal or solid pack mode and the compactor is empty. What switch or device tells the unit to change ram direction? Or is it something else?
I checked the plastic nuts (power nuts) attached to the top of the ram. These nuts drive the ram up/down when the screws turn. Upon inspection, both were cracked. Then the problem made sense. When the ram bottomed, the ram could not exert enough pressure to stall the motor because the power nuts would split open thereby disengaing them from the screws, and so the screws would just keep turning causing the banging noise. Replacing them fixed the problem.
I replaced two hard plastic ram tubes that slide on to the logn screw drives. Now the motor simply hums when I press the start button.
any ideas?
The power nuts have to be threaded onto the screws and attached to the ram. When the unit is turned on, the screws should turn. As they do, the power nuts should follow the threads thus moving the ram downward. Are the screws turning or is the motor just humming? You can view this if you remove the sides of the unit.
The chain is not turning, so the screws are not turning either. The unoit just hums/buzzes when I press the start button. The rams screws are inserted into the ram nuts. I dont know how to remove the sides of th4e compactor. It is fully encased in a metal shell. I can access the screws from inside if I remove cardboard panels, but I can’t run the machine with the door open to view the scews from inside.

I just fixed this. The bottom gear is cracked and the big nut that is turning it is jumping making the banging. My part # was 882699. Don’t buy the cheap one.
