Always cut power before attempting any repair.
- Use a hex wrench to manually rotate the motor and free stuck impellers.
- Prevent jams by feeding scraps slowly and avoiding hard or fibrous items.
- Call a professional if the disposal leaks, makes persistent strange noises, or fails to reset.
Why does a garbage disposal jam?
Jams happen when hard objects like bones or fruit pits get stuck between the impellers and the grind ring. Fibrous materials, such as celery or corn husks, can wrap around the rotating parts. Overloading the disposal with too much food at once can also cause a jam. Sometimes, a foreign object like a utensil accidentally falls in. The motor may overheat and trip the thermal overload, which stops the unit.
How to fix a jammed garbage disposal safely
Start by turning off the power at the circuit breaker to avoid injury. Use a flashlight to inspect the chamber for visible objects. If you see something, use long tongs or pliers to remove it, never your hands. Locate the hex socket on the bottom of the disposal. Insert a 1/4-inch hex wrench and rotate it back and forth to free the impellers. If the wrench doesn't work, try using a wooden broom handle to pry the impellers from above. After clearing the jam, press the red reset button on the bottom of the unit. Restore power and run cold water, then turn on the disposal to test it.
How to prevent future jams
Feed food scraps gradually, not all at once. Avoid putting bones, fruit pits, and fibrous vegetables down the disposal. Always run cold water while the disposal is on and continue for 30 seconds after it stops. Use the disposal regularly to prevent rust and corrosion. Never put grease or oil down the drain, as they can cause clogs that lead to jams.
When to replace a garbage disposal or call a pro
If the disposal still won't turn after clearing a jam and resetting it, the motor may be burned out. Strange noises like humming or grinding can indicate a damaged motor or worn bearings. Water leaks from the unit suggest a cracked housing or failed seals. If you have repeated jams despite proper use, the disposal may be undersized for your household. For any electrical issues or if you're uncomfortable working with wiring, call a licensed plumber or electrician.
