Garbage Disposal Not Working
Most garbage disposal problems are a jam or a tripped overload. Turn off the power, free the flywheel with a hex key from underneath, then press the red reset button. If it stays silent with power on, check the breaker and switch. A disposal that leaks from the body or is over 10 years old usually needs replacing, typically $250 to $600 installed.

Common causes
Jammed flywheel
Hard items such as bones, fruit pits or utensils lock the plate. The motor hums but cannot turn.
Tripped overload
The motor protects itself when overheated or jammed. The red reset button on the bottom pops out.
No power
A tripped breaker, a failed wall switch or an unplugged cord under the sink.
Clogged drain line
Food waste packs the trap or drain pipe after the disposal.
Worn-out unit
Seals fail and the housing corrodes after about 8 to 15 years, causing leaks.
How to fix it, step by step
- 1
Turn the disposal off at the wall switch, then unplug it or switch off its breaker.
- 2
Look into the drain with a flashlight and remove any object with tongs or pliers. Never put your hand inside.
- 3
Insert a 1/4-inch hex key (Allen wrench) into the socket on the bottom center of the unit and work it back and forth until it turns freely.
- 4
Wait 10 minutes for the motor to cool, then press the red reset button on the bottom.
- 5
Restore power, run cold water and switch it on.
- 6
If it is still silent, check the breaker and the wall switch. If it leaks from the body, plan a replacement.

Common questions
Why is my garbage disposal humming but not working?
The flywheel is jammed. Turn off the power, free it with a hex key from the bottom, remove the obstruction, then press the reset button.
Where is the reset button on a garbage disposal?
On the bottom of the unit, usually a small red button near the center. It pops out when the motor overheats.
How long does a garbage disposal last?
Most last about 8 to 15 years. Stainless steel grinding parts and regular use with plenty of cold water help them last longer.
Can I put ice or eggshells in a disposal?
Ice is fine in small amounts. Avoid eggshells, grease, pasta, rice, fibrous vegetables like celery, and bones, which cause most jams and clogs.
