Motor hums but the ram does not move

A humming stalled motor points to a mechanical jam (chain, gear, power nuts, overfilled bin) or a motor/start failure. Unplug quickly; continued humming overheats the motor.

Unplug the compactor (or switch off its breaker) and remove the key before reaching into the cabinet or drawer.
Do not keep re-trying a humming motor; it will overheat.

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.

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.
