Trash Compactor Problem

KitchenAid compactor KUCC151T0. The compactor does not seem to sense when the ram reaches the bottom either when the unit has no trash in it or when the trash pressure should stall the ram. At that point, loud banging occurs. The banging stops automatically after 5 seconds (compactor shuts down) or when the key is turned off. When the unit comes back on (or turned on) the ram reverses and successfully returns to the normal start position. What switch (device) should prevent this problem? Is the directional switch not working correctly or is it something else?

    Right idea, wrong end. The bottom nuts were OK, so I checked on top as well. Turns out there are 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 had same problem with my sears kenmore trash compactor so i replaced motor and switches because unit was 13 yrs. old. That was not the problem, after closer inspection, i found hair line cracks in the hub of the 4 in. plastic drive gear that drove the (2) screws or worm gears. sears parts dept. carried replacement parts. Bag contained both gears plus more parts, tax and shipping totaled $40.00. Problem fixed!!!!!!!!!!!!!!!

Had a similar problem with mine. I took it apart and found that the nut that is on the bottom end of the ram screw was loose. I tightened it and it fixed the problem. That was about a month ago. Now it is doing it again. I'm going to tighten it again this weekend and apply Loc-tite to the threads.

To get to the nut, you have to lay the compactor on its side and remove the plate from the bottom. You'll see a chain that goes around the motor sprocket and both ram screws. You need to tighten the nuts on the ram screws.

Hope this helps.

Compactor wont shut off. is all the way up


Check the upper limit switch, you may only have an issue with the contact arm to sense the rams position. Look there first before buying anything. Good Luck

Trash Compactor Problems Why it Does Not Work

Trash compactors can be a very nice feature and addition to your kitchen. However they can also be very hard to work on if they go bad. There are 20 some brands of trash compactors available, but the KitchenAid trash compactor is one of the most common.

If your trash compactor does not work at all here are some things that you will need to check.
First off make sure that you are getting power to the unit. Many are plug into by code a GFCI wall socket. These outlets do a great job of protecting against shock, but do a terrible job of staying on, especially when used on a motor that pulls a high amount of current when starting. It is not uncommon for them to go bad and trip for no reason at all after a few years. If the outlet is tripped, try to reset it by pushing in hard on the reset button in the center of the outlet.

If you have power at the outlet, then you will need to check through the circuit in the compactor. This can include a door switch, micro switches that sense the position of the ram, and possibly a key switch. Make sure that there is nothing stuck behind the drawer that would keep it from going fully shut. Check the position of the ram to see if it has returned all the way up.

If your ram is stuck down or if it will not go down, check for broken drive gears, belt, of chain. Make sure also that the switches that sense the ram position have not move and come out of place.

Your trash compactor will also need to be clean periodically. Food spilling on the tracks or glides can cause the drawer to slide hard or even become stuck. Clean all the slides or glides, wheels tracks and such with warm damp cloth and the re oil everything with a household lubricant. With time and use the wheels and bearings may also need to be replaced to keep your trash compactor operating well.

Compactor ram stuck partially down & door open 2 inches. How do I get the ram to go back up & get the door closed?

We just had this same problem. Your problem is most likely abroken plastic gear found at underneeath the bottom of the compactor. Pull out the compactor and turn it upside down. Remove the bottom panel and that is where we found the broken gear. We were able to retract the ram and open the drawer by manually turning the drive chain using an ajustable wrench. Clockwise is compact, counter clockwise is retract.

My KitchenAid trash compactor model KUCP021RBL1: cycle does't end

Most likely the motorwindings have been overheated after staying to long time in down position and trying to get up.
If there is a Emerson motor in your compactor than you will not find anything wrong most likely it is the winding of the motor, we have had this two times, changed the motor and the problem is solved.

Kind regards,

GE Profile trash compactor is stuck

This has happened a couple times to me and the fix is fairly simple. The problem is the trash ram is pushing down on the edge of the metal of the trash compartment because the door is partially open. The solution is to back-up the ram the the door will close.

To back-up the ram, you will need to pull the compactor out from under your cabinets and unplug it. Turn the compactor on it's side to expose the bottom. There is a plate on the bottom that covers the motor gears. Remove the plate and turn the large gear counter-clockwise to back-up the ram screws (at least this is how it works on my model works). The gears are a little greasy so you may need to add some after messing with the gears.

Good luck.

Have a Viking trash compactor VUC181 that will not open. Appears latch is broke. How can I get it open?

I have had this same problem and found two causes. Latch was never the problem.
#1 - Ram not in full up position. To check remove top plate and attempt to run compactor - depressing microswitch when ram is at the top. If compactor will not run you can check the ram position by turning the primary screw drive with a ratchet wrench. When ram is at the top position attempt to open the compactor drawer. The stop microswitch seems to frequently bend out of alignment - check the microswitch positioning before resecuring top plate and adjust if necessary.
#2 - Can (or other debris) is wedged in between ram and drawer. Remove back cover and carefully inspect insides of the unit - use a flashlight. Pry out any debris that may impede the drawer from opening. Attempt to open the compactor drawer.

Good luck,
Jon B.

Trash Compactor Removal

I noticed that my compactor attached to the countertop above it at the front, but that it is also possible to do the same at the back. Can you get access under the cabinet at the back of the compactor and check it out?
