Fix a Humming Garbage Disposal: Troubleshooting & Repair · Step 5 of 5
In this video
After removing the obstruction, test the disposal to ensure the repair was successful. First, reconnect the power by plugging the cord back in or flipping the breaker on. Then, turn on the cold water faucet. Running cold water helps solidify any grease and allows it to be chopped up and washed away. Finally, turn on the garbage disposal switch. Listen to ensure it runs smoothly without the previous humming or jamming sound.
Goal: Confirm the disposal is functional
- Always run cold water when using your disposal, not hot. Hot water can liquefy grease, which may then solidify and clog the drain further down the line.

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.
