How to stop a garbage disposal from humming?
Understanding Garbage Disposal Hum
It’s a common household annoyance: you flip the switch, ready to clear away some kitchen scraps, and instead of the familiar grinding sound, you’re met with an unsettling hum. This persistent humming noise from your garbage disposal usually signifies that something is preventing the motor from spinning freely. Ignoring this problem can lead to more significant damage, so understanding how to stop a garbage disposal from humming is crucial for any homeowner.
Why Your Garbage Disposal Hums
The primary reason a garbage disposal hums instead of grinds is a jam. The cutting blades, or impellers, that pulverize food waste are stuck. This can happen for a variety of reasons, from accidentally dropping a hard object like a bone, silverware, or a fruit pit into the disposal, to fibrous or stringy materials like celery stalks or corn husks wrapping around the impellers. Over time, accumulated grease and grime can also contribute to a slowdown and eventual jam.
Troubleshooting the Hum: Your First Steps
Before you panic or reach for the phone, there are a few straightforward steps you can take yourself to try and resolve the humming issue. Safety is paramount here, so always ensure the disposal unit is switched OFF at the wall outlet or the circuit breaker before attempting any of these solutions. Never put your hand inside the garbage disposal.
How to Stop a Garbage Disposal from Humming Safely
The most common and effective method for dealing with a humming garbage disposal involves clearing the jam. Here’s a step-by-step guide:
- Turn Off Power: Double-check that the garbage disposal switch is in the OFF position. For extra safety, locate the circuit breaker that controls the disposal and flip it to the OFF position.
- Inspect from Above (Visually): Using a flashlight, carefully look down into the disposal drain opening. Try to identify any obvious obstructions. If you see something like a spoon or a large piece of food, you might be able to carefully remove it with tongs or pliers.
- Use the Hex Wrench (Allen Wrench): Most garbage disposals come with a small hex wrench (often called an Allen wrench), usually around 1/4 inch. Look for a hexagonal hole in the center of the bottom of the disposal unit. Insert the wrench into this hole and try to rotate it back and forth. This helps to manually dislodge whatever is preventing the motor from turning. You might need to apply some firm, steady pressure. Work the wrench in both directions until you feel it move more freely.
- Reset the Disposal: Once you’ve attempted to clear the jam with the hex wrench, locate the small red reset button, usually found on the bottom of the unit. Press this button firmly.
- Test the Disposal: Restore power by turning the circuit breaker back ON (if you turned it off). Turn on the cold water and then briefly turn on the garbage disposal switch. If you’ve successfully cleared the jam, it should now grind as usual.
If, after trying these steps, your garbage disposal continues to hum, it’s possible the jam is more severe, or there might be another underlying issue with the motor.
When Professional Help is Necessary
While the DIY troubleshooting steps can resolve many common issues with a humming garbage disposal, some situations require the expertise of a qualified professional plumber. If you’ve tried the hex wrench method and the unit still hums, or if you’re hesitant to perform these steps yourself, it’s time to call in the experts. A plumber can accurately diagnose the problem, which could range from a more deeply lodged obstruction to a burnt-out motor, and provide the appropriate repair or replacement.

Preventing Future Garbage Disposal Problems
The best way to avoid a humming garbage disposal in the future is through proper usage and regular maintenance. Understanding what not to put down your disposal is the first line of defense. Avoid putting:
- Fibrous materials (celery, corn husks, asparagus)
- Grease, oil, or fat
- Coffee grounds and eggshells (they can accumulate)
- Hard objects (bones, fruit pits, silverware)
- Non-food items
Running cold water for about 15-30 seconds before and after using the disposal, and continuing to run cold water while grinding, also helps to flush waste through the pipes effectively. Periodically grinding ice cubes can help to clean the grinding components. By following these simple guidelines, you can significantly reduce the risk of encountering a humming garbage disposal again.
