Watch: Garbage Disposal Troubleshooting Tips
In this quick video, Travis from Danco Plumbing Services demonstrates a few simple things to check when your garbage disposal is not working.
Why Is My Garbage Disposal Not Working?
Garbage disposals are built to handle everyday food waste, but they can become jammed or shut down when something prevents the grinding mechanism from turning properly.
Some common reasons a garbage disposal stops working include:
- Food debris causing a jam
- Silverware or foreign objects lodged inside
- An overloaded motor
- A tripped reset button
- Electrical power issues
- Internal wear and tear
Before assuming the disposal needs to be replaced, it’s worth checking a few things first.
⚠️ Safety First: Turn Off Power Before Working on Your Garbage Disposal
Before attempting any troubleshooting, disconnect power to the garbage disposal. Never place your hands inside a disposal or attempt repairs while the unit has power.
What Does Your Garbage Disposal Sound Like?
The sounds your disposal makes can help identify the problem.
If the Disposal Hums But Doesn’t Spin
A humming noise usually means the motor is receiving power, but something is preventing the grinding plate from turning freely. This often indicates a jammed garbage disposal.
Try using the disposal wrench to manually rotate the grinding plate and free the obstruction.
If the Disposal Makes No Noise at All
If you flip the switch and hear absolutely nothing, check:
- The reset button
- The electrical outlet
- Any GFCI outlets nearby
- The circuit breaker
A disposal with no sound is often experiencing a power-related issue rather than a mechanical jam.
Check for a Jammed Garbage Disposal
One of the most common reasons a garbage disposal is not working is a jammed grinding plate.Most garbage disposals come with a small disposal wrench designed specifically for this purpose. If you still have the original paperwork or accessories, check under the sink or near the disposal for this tool.
How to Unjam a Garbage Disposal
Important: Always disconnect power to the disposal before performing any maintenance.
- Locate the hex-shaped opening on the bottom center of the disposal.
- Insert the disposal wrench into the opening.
- Slowly rotate the wrench back and forth.
- Continue until the grinding plate spins freely.
This simple process can often break loose food debris or objects that are preventing the disposal from operating correctly.
If the disposal was humming but not spinning, this step frequently solves the problem.
Check the Garbage Disposal Reset Button
If your garbage disposal won’t turn on and isn’t making any noise, the reset button may have tripped.
Garbage disposals include a built-in safety feature designed to protect the motor from overheating. When the unit becomes overloaded or jammed, the reset button can automatically shut the system down.
When a garbage disposal becomes jammed, the motor may continue trying to operate. To prevent overheating and permanent damage, the disposal’s internal safety switch can trip and shut the unit down. This is why many homeowners find that a jammed disposal also needs to be reset after the obstruction is cleared.
How to Reset a Garbage Disposal
- Locate the reset button on the bottom of the disposal.
- Press the button firmly.
- Restore power if necessary.
- Test the unit.
In many cases, a simple reset is all that’s needed to get the disposal running again.
Verify the Disposal Has Power
Before assuming there’s a plumbing issue, make sure the disposal is receiving power.
Check the following:
- Is the disposal plugged in?
- Has a GFCI outlet tripped?
- Is the circuit breaker turned off?
- Has the wall switch failed?
Electrical issues are often mistaken for disposal failures.
When a Garbage Disposal Needs Professional Repair
If you’ve tried the steps above and your garbage disposal is still not working, there may be a more serious issue requiring professional attention.
Some signs that it’s time to call a plumber include:
- Repeated tripping of the reset button
- Persistent humming without operation
- Water leaking from the disposal body
- Burning odors
- Loud grinding or metal-on-metal noises
- Frequent clogs
- Complete failure after troubleshooting
Attempting further repairs without proper tools can damage the disposal or create a safety hazard.
Can a Garbage Disposal Be Repaired or Does It Need Replacement?
The answer depends on the age and condition of the unit.
In many cases, a clogged or jammed disposal can be repaired quickly and affordably. However, if the motor has failed or the unit is nearing the end of its lifespan, replacement may be the more cost-effective option.
A licensed plumber can evaluate the system and recommend the best solution for your home.
