Listen First:
If you flip the switch for the garbage disposal and don’t hear any noise, the problem is electrical. Follow the steps below if this is the case. Skip down to the next section if you hear a humming noise when you turn on the disposal.- Ensure the garbage disposal is plugged in. This might seem silly at first, but if you have been moving things around under the sink, it’s possible that the plug was knocked loose and could be the reason your garbage disposal won’t turn on.
- Try resetting your garbage disposal. Most garbage disposals have a red reset button near the bottom of the unit. For example, suppose you’ve used your garbage disposal a lot throughout the day. In that case, the garbage disposal may have overheated and automatically turned off to prevent damage. If the unit feels hot, let it rest until it feels cool, hit the reset button, and then try turning it on again.
- Check your circuit breakers. Garbage disposals are often on their circuit in newer homes, so the breaker for the garbage disposal might have tripped even if the power in the rest of the kitchen is still on. If one of our breakers has tripped, try resetting it and then turn the garbage disposal on again.
If you hear a humming sound, but the blades aren’t spinning,
then the problem is likely that your garbage disposal is clogged. Follow the steps below to see if you can get it turning again.- Unplug the garbage disposal – Before you perform any of these, make sure that your garbage disposal is unplugged! You could be seriously injured if the blades start turning again while working on it.
- Look for obstructions in the sink drain – Look down into your garbage disposal through the sink drain for any apparent obstructions like pieces of metal or toys. Don’t try to remove obstructions from clogged garbage disposal with your bare hands. Even if there’s no chance the unit will turn on, the blades are still sharp and could cut your fingers. So, if there are any obstructions, pull them out with a pair of needle-nose pliers and try turning the garbage disposal on to see if that solves the problem.
- Try turning the blades manually. Garbage disposals have “breaker sockets” on the bottom that can be turned using an Allen wrench. The breaker socket is connected to the blades of the garbage disposal. It serves as a way to turn the blades manually if the garbage disposal is clogged. See if you can get the blades turning by hand and, if you can, then flip the switch to the garbage disposal again.
- Hit the reset button – With any of these fixes, it’s a good idea to hit the reset button after you plug the unit back in. Clogged garbage disposals will often shut down automatically to prevent further damage. Once fixed, you must reset the unit to work correctly again.

Frequently Asked Questions
Why does my garbage disposal not turn on at all?
If you flip the switch and hear no noise, the problem is electrical, not a clog. Start by checking that the disposal is plugged in, then check the reset button and the circuit breaker.
Where is the reset button on a garbage disposal?
Most garbage disposals have a red reset button near the bottom of the unit. If the unit was used heavily and feels hot, it may have overheated and shut off automatically, so let it cool before pressing reset.
Why would the disposal breaker trip when the kitchen still has power?
Garbage disposals are often on their own circuit in newer homes, so the breaker for the disposal can trip even while the rest of the kitchen stays on. Resetting that breaker and turning the disposal back on is the next check.
What does it mean when the disposal hums but the blades do not spin?
A humming motor with blades that do not spin usually means the disposal is clogged. Unplug the unit before investigating, since the blades could start moving while you work.
How do I remove an obstruction from the disposal safely?
Look down through the sink drain with the disposal unplugged, and pull out obvious obstructions with needle-nose pliers. Never reach in with your bare hands, because the blades are sharp even when the unit is off.
Can I turn the disposal blades by hand?
Yes. Garbage disposals have breaker sockets on the bottom that connect to the blades and can be turned with an Allen wrench. If the blades turn by hand, plug the unit back in, press reset, and try the switch again.
When should I call a plumber for a clogged disposal?
Call a professional when the reset, breaker, and manual blade checks do not get the disposal running again. At that point the repair needs a plumber, not another round of DIY attempts.
