A broken garbage disposal is one of the most common kitchen headaches, and often one of the easiest to fix. Whether your disposal is humming but not grinding, leaking under the sink, or completely dead, this guide walks you through the causes, the fixes you can safely try yourself, and when it’s time to call a professional (or replace the unit entirely).

Common Garbage Disposal Problems (and How to Fix Them)
1. Garbage Disposal Hums But Won’t Grind
A humming sound means the disposal is getting power but the flywheel is jammed, usually by a bone, utensil, or fibrous food. Turn the disposal off immediately (running it while jammed burns out the motor).
- Insert the hex/Allen wrench (that came with the unit) into the hole on the bottom center of the disposal and turn it back and forth to free the flywheel.
- Remove any visible obstruction with tongs, never your hand.
- Press the red reset button on the bottom, then test.
2. Garbage Disposal Won’t Turn On (No Sound)
Silence means no power reaching the motor:
- Press the reset button on the underside of the unit.
- Check your breaker panel for a tripped breaker.
- Confirm the wall switch and any under-sink outlet are working.
If it still won’t start after resetting and restoring power, the motor has likely failed, time for a professional or a replacement.
3. Garbage Disposal Is Leaking
Where it leaks tells you the cause:
- Top (sink flange): loose mounting or worn plumber’s putty.
- Side (drain lines): loose connection or bad gasket, often an easy tighten.
- Bottom of the unit: an internal seal has failed. This one usually means the disposal needs replacing.
4. Garbage Disposal Is Clogged / Draining Slowly
Never use chemical drain cleaner in a disposal. Instead, disconnect the drain trap and clear the clog manually, or run the disposal with plenty of cold water. Persistent clogs downstream may need a professional.
Repair or Replace? A Simple Rule
Garbage disposals are relatively inexpensive, so the math is different from big appliances. If the motor has failed or the unit is leaking from the bottom, replacement is usually the smarter choice, especially if the disposal is more than 8 to 10 years old. Jams, reset trips, and loose drain connections, on the other hand, are quick fixes.
Garbage Disposal Repair & Installation Cost
A service call to diagnose and fix a jam or leak typically runs $100 to $200. A full replacement and installation (unit included) generally falls between $200 and $400 depending on the horsepower and model. We’ll always give you a clear repair-or-replace recommendation before any work begins.

Frequently Asked Questions
Why does my garbage disposal hum but not spin?
It’s jammed. Turn it off, free the flywheel with the hex wrench in the bottom port, remove the obstruction, and press the reset button.
Where is the reset button on a garbage disposal?
It’s a small red button on the underside (bottom center) of the unit. Press it in; if it clicks and stays, it was tripped.
Is it worth repairing a garbage disposal?
For jams, resets, and loose drain connections, yes. If the motor is dead or it leaks from the bottom, replacing the unit is usually more cost-effective.
