Non-urgent — schedule when convenient

Plumbing

Why won't my garbage disposal turn on?

Garbage disposal not working? Most issues are a 5-second fix. Here's the troubleshooting sequence before calling a plumber.

Most common causes

  • 01Overload — thermal protector tripped
  • 02Humming but not spinning: jam
  • 03No sound at all: power issue or blown reset button
  • 04Leaking: worn seal or cracked body

What to do right now

1
Press the reset button on the bottom of the unit — if it was overloaded, this brings it back
2
If humming but not spinning: turn off, insert an Allen wrench in the hole on the bottom and turn to free the jam
3
Check that the power switch works and the outlet under the sink has power
4
Do NOT put your hand in the disposal

When to call a professional

Call if: the unit hums after clearing the jam (motor may be seized), it's leaking from the bottom (internal seal failure — replace, not repair), or it's over 12 years old and failing repeatedly.
