A sinkhole of electrical problems: why does your garbage disposal overload the breaker?

A malfunctioning garbage disposal can be frustrating, especially when it repeatedly trips the breaker. Understanding the cause behind this issue is crucial for resolving it effectively. This comprehensive guide will delve into the common reasons why garbage disposals trip breakers, providing practical solutions to restore its functionality.

Common Causes of Garbage Disposal Breaker Tripping

1. Overload

Overloading the garbage disposal with excessive food waste can strain the motor and cause it to trip the breaker. Avoid putting large amounts of food scraps, bones, or fibrous materials into the disposal.

2. Jammed Impeller

A jammed impeller prevents the disposal from rotating properly, leading to overheating and breaker tripping. Remove the power and check for any obstructions, such as utensils, silverware, or food scraps, that may be lodged in the impeller.

3. Faulty Motor

A malfunctioning motor can cause the garbage disposal to draw excessive current, resulting in breaker tripping. If the disposal hums but doesn’t rotate, it’s likely a motor issue.

4. Electrical Fault

Loose or damaged electrical connections can cause short circuits, leading to breaker tripping. Inspect the wiring and terminals for any signs of fraying, corrosion, or loose connections.

5. Overheating

Continuous use or excessive load can cause the garbage disposal to overheat, triggering the breaker. Allow the disposal to cool down for 20-30 minutes before using it again.

6. Reset Button Malfunction

A faulty reset button can prevent the breaker from resetting properly. If the breaker trips and doesn’t reset after pressing the button, it may need to be replaced.

7. Incorrect Breaker Size

An undersized breaker may not be able to handle the current draw of the garbage disposal, causing it to trip repeatedly. Consult an electrician to ensure the breaker is rated for the disposal’s amperage.

Troubleshooting and Solutions

1. Clear the Overload: Remove any excess food waste or obstructions from the disposal.
2. Unjam the Impeller: Use a flashlight to inspect the impeller for any lodged items. Remove them carefully using pliers or tongs.
3. Check the Motor: If the motor hums but doesn’t rotate, contact a qualified electrician for repair or replacement.
4. Inspect the Electrical Connections: Tighten any loose connections and replace damaged wires.
5. Allow Cooling Time: If the disposal has overheated, allow it to cool down before using it again.
6. Reset the Breaker: Press the reset button firmly. If it doesn’t reset, replace the breaker.
7. Consult an Electrician: For electrical faults or incorrect breaker size issues, seek professional assistance from a licensed electrician.

Prevention Tips

• Avoid overloading the garbage disposal.
• Regularly clear food scraps and debris from the impeller.
• Use cold water while running the disposal to prevent overheating.
• Run the disposal for short intervals to avoid motor strain.
• Install a garbage disposal with a higher horsepower rating for heavy-duty use.

Information You Need to Know

1. Why does my garbage disposal smell bad?

Food scraps and bacteria can accumulate in the disposal, causing odors. Run the disposal with a mixture of baking soda and vinegar, or use a commercial disposal cleaner.

2. Why does my garbage disposal make a grinding noise?

A dull impeller can cause grinding noises. Sharpen the impeller by running the disposal with a few ice cubes or eggshells.

3. Why does my garbage disposal not turn on at all?

Check if the disposal is properly connected to the power supply. Also, make sure the reset button has not tripped.
