You flip the switch—and instead of grinding, your garbage disposal just hums.
This is a common (and frustrating) issue for homeowners in Lake Forest and throughout Orange County. The humming sound usually means the unit is receiving power, but something is preventing the blades from turning.
In most cases, this problem is caused by a jam or mechanical issue that needs attention before the disposal can function properly again.
If your garbage disposal is humming but not working, the team at Mr. Rooter Plumbing of Orange County can safely diagnose and repair the issue.

🔊 What Does the Humming Sound Mean?
When your garbage disposal hums, it means the motor is running—but the internal grinding components are stuck.
This can happen when something blocks the impellers (the spinning parts inside the unit), preventing them from moving.
If the motor continues to run while jammed, it can overheat and potentially damage the unit.
That’s why it’s important to address the issue quickly.
🥄 Common Causes of a Jammed Garbage Disposal
Several types of materials can cause a disposal to jam.
The most common culprits include:
- Utensils accidentally dropped into the disposal
- Bones or hard food scraps
- Fibrous foods like celery or corn husks
- Grease buildup
- Eggshells or coffee grounds
These items can block the blades and stop the unit from spinning.
⚠️ Why You Shouldn’t Keep Running It
If your garbage disposal is humming but not turning, avoid repeatedly flipping the switch.
Running a jammed disposal can:
- Burn out the motor
- Damage internal components
- Trip the circuit breaker
- Lead to complete unit failure
Turning it off immediately can help prevent further damage.
🔧 How to Reset the Garbage Disposal
Many garbage disposals have a built-in reset button, typically located on the bottom of the unit.
If the disposal overheats, this button may trip to protect the motor.
To reset the unit:
- Turn off the disposal and unplug it if possible.
- Locate the reset button underneath the unit.
- Press the button firmly.
- Turn the disposal back on.
If the unit still hums without spinning, the issue may be a jam.
🧰 How to Manually Free a Jam
Some minor jams can be cleared manually.
Many garbage disposals have a hex-shaped opening at the bottom for a wrench.
To attempt to free the jam:
- Turn off power to the unit.
- Insert an Allen wrench into the bottom slot.
- Rotate the wrench back and forth to loosen the jam.
Important: Never put your hand inside the disposal.
If the jam cannot be cleared easily, it’s best to call a professional.
🔌 Electrical or Motor Problems
In some cases, the issue may not be a jam at all.
Possible electrical or mechanical problems include:
- A failing motor
- Loose wiring connections
- A damaged internal component
If the disposal does not respond after resetting or freeing a jam, it may need repair or replacement.
🧴 Grease Buildup Inside the Disposal
Grease and oil can accumulate inside the disposal and harden over time.
This buildup can:
- Restrict movement of internal components
- Cause the unit to jam
- Lead to slow drainage
Regular cleaning and proper disposal habits can help prevent grease-related issues.
🏡 How to Prevent Garbage Disposal Problems
Homeowners can extend the life of their garbage disposal by following simple guidelines:
- Avoid putting hard or fibrous foods down the disposal
- Never pour grease or oil into the unit
- Run cold water while using the disposal
- Clean the unit regularly
- Use the disposal only for appropriate food waste
Proper use helps prevent jams and mechanical issues.
⚠️ When to Call a Professional Plumber
While some minor jams can be resolved at home, other problems require professional attention.
You should call a plumber if:
- The disposal continues humming after resetting
- The unit frequently jams
- There are unusual noises or vibrations
- The disposal stops working completely
The experienced team at Mr. Rooter Plumbing of Orange County can safely repair or replace your garbage disposal.
