Single sourceBrands: GE, GE Profile7 components

Classic 1/3 HP power-screw compactors: a key-knob start/off switch, a drawer monitor (safety) switch, an automatic thermal motor cutout, and a foot pedal to open the drawer. About a one-minute cycle. Calls are almost always 'won't start' (key, drawer, switch), 'won't stop' (top limit / directional switch), a stuck ram, and odor.

Safety first

Unplug before removing panels; never reach under a ram that could move.
Do not defeat the drawer switch for testing with the drawer open.
Live-voltage tests are caution.

How it works

Turning the key knob to START with the drawer closed completes the circuit through the drawer monitor switch; the motor drives the power screws through a chain/gear set and the ram travels down, compacts, reverses and returns to the top.

A directional / top-limit switch, tripped by a tab on the ram, reverses the motor at the bottom and stops it at the top. If the top-limit function fails, the compactor keeps running after the cycle should end.

The drawer will not open unless the ram is fully raised. If the ram is stuck down, GE's guidance is to lift up on the foot pedal and follow the article steps rather than force the drawer.

An automatic thermal motor protector stops the motor if it overheats; wait a few minutes and restart.

Diagnostic guides for this appliance

Guide · Trash Compactor

Trash compactor won't stop: ram keeps cycling or runs past the top

A compactor stops when the ram returns to the top and trips the top-limit/directional switch, which also tells the motor which way to run. If the ram never stops, suspect that switch or its actuator, a start/run or push-button switch stuck closed, or a motor centrifugal/reversing switch problem. Unplug before any check.

Guide · Trash Compactor

Trash compactor doesn't compact well (ram goes down but trash stays loose)

Weak compaction on a power-screw compactor usually means the ram isn't getting full force: worn or stripped power nuts, a slipping or broken drive gear or sprocket chain, or worn screws. Running the unit nearly empty is a common cause of gear damage. Inspect from below with the unit unplugged and pulled out.

Guide · Trash Compactor

Trash compactor won't start: test the key, drawer, tilt and top-limit switches

A compactor start circuit is a chain of switches in series. Prove the outlet first, then continuity-test each switch with the power off: on-off / key switch, momentary start, drawer safety, tilt and top-limit / directional. If every switch passes, the motor's centrifugal switch, the motor or the wiring is next.
