If your garbage disposal keeps tripping the reset button, it’s trying to protect the motor from damage. While a worn-out disposal is one possibility, many reset problems are caused by jams, overloads, or electrical issues that can often be corrected without replacing the unit.
Before buying a new garbage disposal, check these common causes.
- Look for a Jam
The most common reason a disposal trips its reset button is a jammed grinding plate.
Possible causes include:
- Bones
- Fruit pits
- Silverware
- Bottle caps
- Hard food scraps
Turn off the power and use the manufacturer’s disposal wrench to rotate the grinding plate from underneath.
- Avoid Overloading the Disposal
Running too much food through the disposal at once can overload the motor.
Feed food gradually while running cold water to help flush debris through the unit.
- Check for a Dull Grinding Plate
Older disposals can become less effective over time.
A worn grinding mechanism makes the motor work harder and may cause repeated overload trips.
- Inspect the Wiring
Turn off power at the breaker before inspecting any wiring.
Look for:
- Loose wire connections
- Burn marks
- Melted insulation
- Damaged power cord
Electrical problems can cause intermittent operation.
- Verify Proper Voltage
A weak electrical connection or damaged outlet can affect disposal performance.
If the disposal hums or frequently trips, test the outlet and circuit.
- Check the Reset Button
After clearing any jams, allow the motor to cool for several minutes before pressing the reset button.
If it trips again immediately, another issue is likely present.
- Consider Motor Failure
If the disposal is more than 10 years old and continues to trip after clearing jams and checking wiring, the motor may be failing.
Signs include:
- Burning smell
- Loud humming
- Grinding noises
- Frequent overheating
At this point, replacement is often the most cost-effective solution.
Safety Reminder
Always disconnect power before placing tools near the disposal or inspecting electrical connections.
Final Thoughts
A garbage disposal that repeatedly trips the reset button is often suffering from a jam, overload, or electrical issue—not necessarily a failed motor. Taking a few minutes to inspect the unit can save the cost of an unnecessary replacement.
