Garbage Disposal Jammed or Dead? Try These Steps Before Calling Anyone
A jammed garbage disposal is one of the few appliance problems where a homeowner can sometimes solve it in five minutes with no tools. Here is the correct process — and when it is time to stop trying and call a technician.
- Never put your hand inside a garbage disposal, even when it is unplugged.
- A hex wrench inserted into the bottom of the unit can manually free most simple jams.
- A humming sound with no spinning almost always means a physical jam, not a motor failure.
- If the reset button trips repeatedly after clearing a jam, the motor itself may be failing.
First: Turn Off the Power
Before doing anything else, switch off the disposal at the wall switch and, if possible, unplug it or shut off the breaker. Never place your hand inside a garbage disposal, even when you believe it is off — the blades (technically impellers) can move unexpectedly.
Step 1: Identify the Type of Failure
A disposal that hums but does not spin when switched on almost always indicates a physical jam — something is blocking the impeller from turning. A disposal that produces no sound at all when switched on is more likely an electrical issue, such as a tripped reset button or a wiring problem.
Step 2: Try the Manual Turning Method (For Jams)
Most garbage disposals have a small hexagonal opening at the very bottom of the unit, underneath the sink. Insert a 1/4-inch hex wrench (many disposals include one, or a standard hardware store hex key works) and turn it firmly back and forth. This manually rotates the impeller and often breaks whatever is causing the jam free.
Step 3: Press the Reset Button
After manually freeing the jam, locate the small red reset button on the bottom or side of the unit and press it. This resets the internal circuit breaker that trips automatically when the motor overheats or stalls against an obstruction.
Step 4: Turn the Power Back On and Test
Restore power, run cold water, and switch the disposal on briefly to test. If it spins freely and sounds normal, run water through it for another minute to clear any remaining debris.
What Commonly Causes Jams
- Fibrous vegetable scraps like celery, corn husks, or onion skins
- Utensils or small objects accidentally dropped down the drain
- Bones or fruit pits, which disposals are not designed to handle
- Excessive grease that hardens inside the chamber
When to Stop and Call a Technician
If the manual turning method does not free the jam, if the reset button trips again shortly after you restore power, or if you hear a burning smell at any point, stop troubleshooting. A disposal that keeps tripping its reset after a cleared jam usually has a failing motor, and continuing to force it risks a more expensive repair or a full replacement rather than a straightforward fix.
Preventing Future Jams
Run cold water (not hot) while operating the disposal, avoid fibrous or starchy scraps entirely, and never use it as a substitute for a trash can for anything beyond small food waste. These habits alone prevent the large majority of jam-related service calls we see across Mableton.

No. Never place your hand inside a garbage disposal, even when it appears to be off. Always use a hex wrench from underneath the sink.
