Understanding Garbage Disposal Humming
When you encounter a garbage disposal that’s humming but not functioning, it often signifies underlying issues that need to be addressed. Understanding the causes and impact of this humming can help you determine the best course of action.
Causes of Humming
A humming sound from your garbage disposal typically indicates that the motor is still trying to run, but the disposal’s grinding mechanisms can’t turn. The most common cause of this is an overload or jam, where foreign objects or a buildup of food scraps obstruct the grinding mechanism or slow the drainage, triggering a shut-off to prevent damage or motor burnout (Mr. Appliance).
Another potential cause is a jammed inner flywheel or seized motor bearing. If the motor’s internal components can’t move freely, they can cause the unit to hum when turned on. It’s crucial to switch off the unit promptly to prevent further damage and then try to free the flywheel using appropriate methods (Mr. Appliance).
Cause | Description | Immediate Action |
---|---|---|
Foreign Objects | Items caught in blades | Check for obstructions and attempt to remove with tools |
Motor Issues | Malfunctioning or jammed motor | Reset motor or seek professional help |
Drain Clogs | Blocked drain preventing water flow | Clear the drain using a plunger or snake |
Impact of Humming on Disposal
If your garbage disposal is humming but not spinning, it’s a signal that the unit is experiencing an issue that could lead to more severe damage if not addressed. Continual humming without action can strain the motor, leading to overheating or eventual failure. The longer the problem persists, the higher the risk of the motor burning out, which might necessitate a complete disposal replacement.
Moreover, a humming garbage disposal left unattended can also contribute to a clogged sink or backup issues, adding to the inconvenience and potential costs for repair. Therefore, addressing the humming sound promptly will not only ensure your disposal is running efficiently but also help maintain its longevity and prevent further plumbing complications.
Understanding the causes and impacts of garbage disposal humming is the first step in troubleshooting the problem.

Troubleshooting Humming Disposals
If your garbage disposal is humming but not operating correctly, it could indicate a jam or an issue with the motor. It is imperative to address these sounds promptly to prevent further damage to the unit.
Clearing Foreign Objects
The presence of foreign objects is a common cause of a humming garbage disposal. These objects may obstruct the grinding mechanism, leading to a jam that halts the unit’s function. To address this:
- Ensure the unit is turned off and unplugged for safety.
- Inspect the disposal’s chamber using a flashlight to locate any visible obstructions.
- If an object is detected, use a pair of pliers or tongs to carefully remove it. Avoid putting your hand into the disposal.
If you cannot see or remove the obstruction easily, consider using a hex key or a garbage disposal wrench to manually rotate the disposal’s grinding plates and dislodge the item. Always make sure the power supply is disconnected before attempting this method for your safety.
Resetting the Motor
In cases where the disposal unit has shut off due to an overload or jam, the motor may need to be reset. This is a simple process that can often resolve the humming issue:
- Locate the reset button on the bottom of the disposal unit.
- Press the button firmly. If it does not stay in, wait a few minutes and try again.
- Once the button is reset, turn on the power and test the disposal.
If the disposal is still not functioning correctly and continues to hum, the issue may be more complex and could involve a ceased motor bearing. In such instances, it is advisable to seek assistance from a professional technician for a comprehensive diagnosis and repair (Mr. Appliance).
Addressing Drain Clogs
A clogged drain can also cause your disposal to hum without grinding. To resolve a drain clog:
- Use a plunger to attempt clearing the blockage.
- If unsuccessful, try a plumbing snake to dislodge the clog.
- Detach the drain pipe under the sink to inspect for clogs and clean it out if necessary.
These steps can help restore proper drainage, which may alleviate the humming and allow your disposal to operate smoothly. If the clog persists after these efforts, professional plumbing assistance may be required (Your Guy Drainage).

Fixing a Humming Garbage Disposal
When your garbage disposal begins to hum instead of grind, it can be a sign of a jam or an issue with the motor. Before you call a professional, there are a few troubleshooting steps you can take to try to resolve the problem on your own.
Manual Rotation Techniques
If your garbage disposal is humming but not working, it may be due to a jammed inner flywheel or a ceased motor bearing. It’s imperative that you first ensure the disposal is turned off before attempting any manual fixes. You can try to manually turn the blades using an Allen wrench on the bottom of the disposal unit. Insert the wrench into the flywheel turning hole and rotate back and forth to free any obstructions. If the disposal is jammed, this may help to dislodge the jam and allow the blades to move freely again.
Utilizing the Reset Button
A common cause of a disposal malfunction is an overload or jam that triggers the unit’s safety feature and causes it to shut off. This is often accompanied by a humming noise but no grinding action. To address this, locate the reset button, typically located at the bottom of the unit. Press the reset button and wait a few minutes before trying to turn on the disposal again. If the disposal has overheated, allow it to cool down before attempting the reset.
Dislodging Obstructions
Foreign objects or a buildup of food scraps can obstruct the grinding mechanism, causing the disposal to hum and become clogged. To clear these obstructions, turn off the power to the disposal at the circuit breaker. Then, use pliers or tongs to carefully remove any visible foreign objects from the disposal chamber. If the disposal is stuck, avoid putting your hand inside the disposal, as this can be dangerous.

Ensuring Safety and Longevity
Maintaining your garbage disposal is not just about fixing immediate problems like humming and leaking; it’s also about ensuring safety during repairs and extending the lifespan of the unit. Here are some essential power safety measures and tips for prolonging the life of your garbage disposal.
Power Safety Measures
Before attempting any maintenance or repairs on your garbage disposal, safety must be your top priority. You should always unplug the unit’s power cord from the outlet under the sink to eliminate any risk of electrical injury. This is a crucial step whether you’re dealing with a garbage disposal not working humming or a disposal that’s humming but not spinning (Pippin Brothers).
If your garbage disposal unit does not have a plug, as is the case in some installations, you must locate the circuit breaker that controls the disposal and turn it off. This ensures that no power is supplied to the disposal during your repair work.
Extending Disposal Lifespan
The key to extending the lifespan of your garbage disposal is regular maintenance. Garbage disposals can last approximately 10 to 15 years, but this can vary based on the quality of the unit, how frequently it is used, and how well it is maintained (Mr. Appliance).
Here are some tips to help you maintain your garbage disposal and extend its lifespan:
- Run your disposal regularly to prevent rust and corrosion.
- Always use cold water when grinding food waste, as it solidifies any grease or oils, making them easier to grind.
- Grind citrus peels in the disposal occasionally to keep it smelling fresh.
- Clean the disposal by grinding ice cubes, which can help knock off any debris buildup on the sharp edges that keep the waste grinding capabilities efficient.
- Avoid disposing of hard objects, large bones, fibrous materials, and non-food items which can cause jams or damage to the blades.
To prevent future leaks, conduct a simple test periodically by pouring food coloring mixed with water down the drain. This test will help you identify the source of any leaks before they escalate into a major issue (Magnolia Companies). Regular checks and proactive maintenance can save you from the hassle of dealing with complex garbage disposal issues like clogging, jams, or stuck disposals.
Remember, if your unit nears the end of its life and you experience persistent problems such as humming and smoking or not draining, it might be time to consider a replacement instead of a repair (The Spruce).
By following these power safety measures and maintenance tips, you can safely repair and maintain your garbage disposal, ensuring it serves you effectively for many years.
