Quick Answer
If your garbage disposal keeps tripping the breaker, it’s usually caused by a jammed motor, electrical overload, or moisture inside the unit. Clearing jams and reducing strain fixes the issue in most cases.
Why This Happens
Garbage disposals draw a lot of electrical current when starting. If the motor is jammed, overheated, or struggling due to dull impellers, it pulls excess power and trips the breaker as a safety measure. Water intrusion or aging wiring can also cause repeated trips.
Breaker‑related disposal problems are common and well documented in
Garbage Disposal Troubleshooting.
What NOT to Do
Do not keep resetting the breaker without fixing the cause. Never reach into the disposal with your hand, even if the power is off. Avoid pouring grease, fibrous foods, or bones into the disposal, which can worsen electrical strain.
Step-by-Step Fix
- Turn off power to the disposal at the breaker panel.
- Use a flashlight to check for visible obstructions inside the disposal.
- Insert a hex (Allen) wrench into the bottom slot and manually rotate the motor.
- Press the red reset button on the bottom of the disposal.
- Restore power and run cold water while testing the unit.
- If the breaker trips again, stop using the disposal immediately.
Alternative Fixes
If clearing jams doesn’t help, the motor windings may be failing or moisture may be shorting the unit. In older disposals, repeated breaker trips often signal the end of the unit’s lifespan.

Garbage Disposal Troubleshooting.
Prevention Tips
Always run cold water when using the disposal and avoid grinding hard or fibrous foods. Cut waste into smaller pieces to reduce motor strain. Preventive habits outlined in
Garbage Disposal Troubleshooting help prevent breaker trips and motor burnout.
FAQs
- Is it dangerous if my garbage disposal keeps tripping the breaker? Yes. It can indicate electrical faults or motor failure.
- Can a dull disposal blade trip the breaker? Yes. Increased resistance makes the motor draw more power.
- Should I replace the disposal if it keeps tripping? If fixes don’t work, replacement is often safer and cheaper.
