Fix a Humming Garbage Disposal: Troubleshooting & Repair · Step 2 of 5
In this video
Go under the sink and locate the center opening on the very bottom of the garbage disposal unit. Insert the standard service wrench, which is essentially a custom Allen wrench, into this opening. Apply pressure and move the wrench back and forth in a rocking motion. This directly turns the motor shaft and can effectively dislodge obstructions.
Goal: Manually turn the motor from underneath to free the jam.
- Most garbage disposals come with this tool. If you've lost it, a 1/4 inch Allen wrench is often a suitable replacement.

FAQs
My garbage disposal is humming but not grinding. What's the very first thing I should do before attempting any repairs?
The absolute first step is to prioritize safety by disconnecting all power sources to the disposal. This includes flipping the circuit breaker, turning off the wall switch, and unplugging it if accessible. This prevents accidental activation while you're working inside the unit.
I don't have a specific 'disposal wrench' or Allen wrench for the bottom hole. Can I use a different tool to free the jam?
While a dedicated disposal wrench or a 1/4-inch hex Allen wrench is ideal for the bottom hole, you can also try turning the grinding plate from the top using a wooden broom handle. For removing debris from the drain opening, long-handled tongs or needle-nose pliers are essential. Never use your hand for this task.
I used the wrench and removed visible debris, but my disposal is still humming after I restore power. What should I do next?
If humming persists after clearing a jam and restoring power, the motor might be overheated. Allow it to cool for 15-20 minutes, then press the red reset button usually found on the bottom of the unit. If it still hums or doesn't turn on, the motor might be seized or burned out, indicating it's time to contact a plumber or consider replacement.
What's the safest way to remove debris from inside the disposal, especially if I can't see it well?
Always ensure power is disconnected before inspecting the disposal's interior. Use a flashlight to illuminate the chamber and then carefully remove any obstructions with long-handled tongs or needle-nose pliers. Never use your bare hands, as the grinding components are sharp, even when not moving.
