For Garbage Disposal Does Not Turn On - Jammed or Dead, start with "Press the red reset button under the unit first": Look underneath the sink at the garbage disposal. There is a small red or black button - the overload protector. Press it firmly until it clicks. If it was tripped, the unit may come back to life immediately. If it trips again, the jam is still there or the motor is bad. Stop DIY if water is leaking from the disposal body or the drain connection - replace the unit. This is listed as a easy recovery and usually takes about 10 min.

help1. Understand the Problem

A disposal that will not run usually has one of three causes: something lodged between the impellers (jam), the overload protector tripped from overheating, or the motor itself died. The reset button under the unit is your first diagnostic tool - if it pops out, the motor overheated. If it stays in and there is no hum, the motor is likely gone.

Best First Step

Press the red reset button under the unit first

Look underneath the sink at the garbage disposal. There is a small red or black button - the overload protector. Press it firmly until it clicks. If it was tripped, the unit may come back to life immediately. If it trips again, the jam is still there or the motor is bad.

Insert an Allen wrench into the bottom socket to manually free the jamThe disposal has a hex socket on the bottom center - it takes a 1/4 or 3/8 inch Allen wrench. Insert it and turn back and forth like a ratchet. You will feel it catch on something solid. Rock it gently until the impellers turn freely. This manually frees whatever is jammed without disassembly.

Check the wall switch - flip it on and off rapidly three timesMany disposals are activated by a wall switch. Flip it off and on rapidly 3-4 times. This sends a pulse sequence that sometimes clears a stuck motor. If the disposal hums but does not run after this, the jam is not cleared. If there is no hum at all, the motor is likely done.

Verify power at the outlet with a voltage testerUnplug the disposal or turn the breaker off. Pull the disposal out to access the outlet. Use a voltage tester to confirm 120V at the socket. No voltage = circuit problem upstream. If voltage is present and the reset does not help, replace the disposal.

Look down the drain with a flashlight before resettingShine a light down the drain. If you can see a foreign object like a spoon, glass shard, or bone, use long-nose pliers to pull it out. Never put your hand in the disposal.

Replace the disposal if the motor is deadIf pressing reset and clearing the jam do not work, and you have confirmed 120V at the outlet, the motor is burned out. Replace the unit - they typically last 10-15 years under heavy use.

Frequently Asked Questions

Why is my garbage disposal humming but not spinning?expand_more

It is jammed, not dead. The motor is running but the impellers cannot turn. Use an Allen wrench on the bottom socket to manually free it. Never reach in with your hand.

How do I know if the garbage disposal motor is burned out?expand_more

If the reset button does not help, the unit does not hum, and you have confirmed 120V at the outlet, the motor is dead. Time for a replacement.

Can I reset the garbage disposal without the button?expand_more

The reset button is the thermal overload protector. If it is missing or broken, the unit likely needs replacement. Some older models do not have one - in that case, check the jam first.
