Trash Compactors

Trash compactor motor runs but the ram does not move

If the motor turns freely, the fault is in the drive train between the motor and the ram: drive chain or belt, sprockets/gears, or the plastic power nuts that ride the power screws. A broken directional/limit switch can also leave the screws turning the wrong way or not at all.

Undercounter compactors slide into a standard opening and plug into a grounded 120 V outlet placed beside the unit. Check the opening height so the top clears the counter, level the unit and secure it as the instructions require.

Trash compactor will not start

Most no-starts are power, an unlatched drawer, or the start sequence (key to Start, or On plus foot-actuated start). After that, test the drawer, key/start, toe/foot and directional switches, then the motor.

Ram stuck down or will not travel

Check the drive chain/gears, then the directional switch, then the power nuts on the power screws. The ram can be raised by turning the drive gear by hand with the unit unplugged.
