How to Fix a Garbage Disposal – Complete Checklist

Garbage disposals are a modern kitchen convenience, but when they stop working, they can quickly become a source of frustration. Luckily, many common garbage disposal issues can be fixed with a bit of troubleshooting. Follow this complete checklist to get your disposal running smoothly again.

1. The Garbage Disposal Won’t Turn On

Check the Power: Ensure the unit is plugged in and check for a tripped circuit breaker. Many disposals have a reset button located at the bottom of the unit; press it to reset the motor.

Inspect the Wall Switch: If the disposal doesn’t respond, the issue might lie in the wall switch or wiring. Replacing a faulty switch often resolves the problem.

2. The Disposal is Jammed

Turn Off the Power: Always disconnect power before attempting to clear a jam.

Use a Hex Key: Insert the hex key (often included with the unit) into the manual crank slot underneath the disposal to free the jammed impellers.

Remove Visible Debris: Use tongs or pliers to remove any visible obstructions—never use your hands.

3. Unpleasant Odors from the Disposal

Clean the Disposal: Run cold water while grinding ice cubes to clean the blades.

Use Natural Deodorizers: Pour in a mix of baking soda and vinegar, let it sit, and rinse with hot water.

Check for Trapped Food: Inspect the rubber splash guard for trapped food particles and clean it thoroughly.

4. Leaking Garbage Disposal

Inspect the Connections: Tighten loose mounting bolts or hose clamps around the dishwasher and drainpipe connections.

Replace Worn Seals: If leaks persist, the issue might be a worn-out seal or gasket, which can be replaced with a new part.

5. The Disposal Makes Loud Noises

Look for Foreign Objects: Metallic clattering often indicates a foreign object is stuck in the disposal. Turn off the power and carefully remove the item.

Check for Loose Components: Tighten any loose screws or parts inside the disposal unit.

Pro Tips for Garbage Disposal Maintenance

Run Cold Water: Always run cold water when using the disposal to prevent overheating.

Avoid Hard or Fibrous Foods: Items like bones, corn husks, and potato peels can damage the blades or clog the system.

Grind Regularly: Frequent use helps prevent rust and keeps the motor in good shape.
