Know what you’re replacing.
If your disposal hums but won't spin, it's jammed. If it's silent, it has tripped its reset or lost power. Both are usually fixable in minutes. Never put your hand in the disposal, even when it's off.

A little preparation first.
- Turn the disposal switch off and unplug it or switch off its breaker.
- Use a flashlight to look inside — never your hand.
One step at a time.
2Remove anything stuck
Look inside with a flashlight and pull out objects with tongs or pliers.
3Unjam from below
Insert the ¼" hex key into the socket in the center of the bottom and work it back and forth until it turns freely.
4Press the reset button
Press the red reset button on the bottom. If it won't stay in, wait 10 minutes for the motor to cool.
5Test with cold water
Remove all tools from the disposal, restore power, run cold water and switch it on. If it hums again, switch it off at once and repeat the unjam step; if it keeps tripping, call a plumber or electrician.
