Likely causes
- CommonDrawer not fully closedMost compactors won't run unless a safety switch detects the drawer is completely shut.
- CommonTripped breaker or unplugged unitCompactors draw significant power and can trip a dedicated circuit.
- PossibleKey switch not fully turned or wornModels with a key-operated start need the key turned firmly to the correct position.
- PossibleFaulty door/drawer safety interlock switchThe switch that senses the drawer is closed can fail and never signal 'closed' even when it is.
What to do
- Push the drawer firmly closed and listen or feel for a click from the interlock switch.
- Check the breaker panel for a tripped breaker dedicated to the compactor and reset it if needed.
- Confirm the unit is plugged in securely if accessible.
- Try the key switch again, turning firmly and holding briefly if your model requires it.
- Unplug the unit and, with power off, check the visible portion of the door switch for obvious damage or a stuck plunger.
- Have the interlock switch tested and replaced if it seems to be the cause and you're comfortable with basic appliance repair, or call a technician.

When to call a pro
Call an appliance technician if the breaker and drawer checks don't fix it, since diagnosing the interlock switch or motor may need testing tools.
