Garbage Disposal Jammed? Unstick It in 2 Minutes

A humming or dead garbage disposal is usually jammed, not broken. The two-step reset-and-wrench fix, straight from InSinkErator’s official guidance.

Hum = jam, silence = tripped breaker

If the disposal hums but won't turn, the flywheel is jammed by something hard. If it is completely dead, the overload protector likely tripped. Both are two-minute fixes you do yourself — and both should be done with the disposal switched off. Never put your hand down the disposal.

Step 1: free the jam with the wrench

Per InSinkErator's official support: turn off the disposal at the switch, then insert the hex (Allen) wrench that shipped with the unit into the center hole on the bottom of the disposer and work it back and forth until the flywheel turns freely. No wrench? A quarter-inch Allen key fits most units. This dislodges whatever is stuck.

Step 2: press the reset button

If the disposal is dead, find the small red reset button on the bottom of the unit. If it has tripped it will have popped down about a quarter inch. Per InSinkErator, gently press it back in; if it won't stay, wait ten minutes for the motor to cool and try again. Then run cold water and switch the disposal on.

What not to do, and when to call

Don't use chemical drain cleaners (they damage the seals) and don't force it with a broom handle. If the unit won't reset after cooling, leaks from the bottom, or trips repeatedly, the motor or seals are likely failing — and a leaking or motor-dead disposal is a replacement, not a repair. If it is not a simple jam or reset, have a vetted local pro or plumber confirm. Find appliance and disposal pros near you.

Frequently Asked Questions

  2. Where is the reset button on a garbage disposal? A small red button on the bottom of the unit. If it has tripped it pops down about a quarter inch; press it back in, waiting ten minutes if it won’t stay.
  3. Should I use drain cleaner on a jammed disposal? No — chemical drain cleaners can damage the disposal and seals. Use the wrench-and-reset method instead.
