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.

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.
