Why Is My Garbage Disposal Humming?
If your garbage disposal hums but does not spin, the motor may be jammed or overheated. This is a common kitchen plumbing issue in South Florida homes. Try these safe troubleshooting steps first. If the disposal still will not run or you smell burning odors, Amy’s Plumbing can help.
Common Reasons a Garbage Disposal Hums
Jammed Impellers
Food debris or hard objects may block the disposal blades from spinning.
Overheated Motor
The disposal may shut down temporarily if the motor overheats.
Foreign Objects
Silverware, bones, bottle caps, or utensils may become lodged inside the unit.
Worn Disposal Components
Older garbage disposals may develop internal mechanical failure over time.
Step 1: Turn Off Power First
Before inspecting the disposal, turn the unit off completely and avoid putting your hands inside the disposal chamber.
Never place your fingers into a garbage disposal, even if it appears turned off.
If needed, switch off power at the wall switch or breaker before checking for visible obstructions.
Step 2: Look for Visible Objects Safely
Use a flashlight to inspect the disposal opening. Look for visible objects such as utensils, bones, fruit pits, or debris.
If something is clearly visible near the top, use tongs or pliers to remove it carefully. Never use your hands.
Step 3: Press the Reset Button
Most garbage disposals have a small reset button located underneath the unit.
If the motor overheated, pressing the reset button may restore operation after the unit cools down.
Wait several minutes before attempting to restart the disposal.

Avoid Unsafe Garbage Disposal Repairs
Garbage disposals combine electricity, water, and moving components. Avoid taking the disposal apart unless you are trained to do so safely.
Do not continue forcing the disposal to run if it hums loudly without spinning. This may damage the motor further.
