Most Frequent Causes for Garbage disposer trips breaker or reset button

For the most accurate results, enter your model number.


Cause 1Plate is Jammed

The shredding plate might be jammed or worn out. Most disposers have an opening at the bottom of the housing. If the shredding plate is stuck, insert either a disposer wrench or a ¼ inch Allen wrench into the bottom of the disposer and wiggle the shredding plate back and forth until it moves freely. If the disposer does not have an opening at the bottom, insert a broom handle into the drain opening and try to wiggle the plate.

Cause 2Non-Serviceable Motor

This indicates that the motor is defective or that the motor bearings are worn out. The disposer motor is not replaceableā€”if the disposer motor is defective or worn out, you must replace the entire disposer.

Cause 3Overload

If the garbage disposer keeps tripping the breaker or reset button and you've determined the shredder plate turns freely and there is no water leak, then it's likely the overload is faulty and not monitoring the voltage appropriately. You should be able to replace the overload to resolve the issue.

The switch protects the motor when the grinding plate gets jammed, but if the switch malfunctions and doesn't interrupt the voltage as designed, the breaker or reset button may continue to trip. You can use a multimeter to test the safety switch for electrical continuity or a short and replace the component if necessary.
