No More Buzzing: Fixing a Jammed and Humming Garbage Disposal

Understanding Garbage Disposal Humming

When your garbage disposal begins to emit a humming sound, it can be a sign that something is not quite right with the unit. Understanding the causes behind this humming noise and the impact of foreign objects can help you address the problem effectively.

Causes of Garbage Disposal Humming

A humming sound from your garbage disposal usually indicates that the motor is powered but the blades are not turning. Here are a few reasons why your disposal might be in this state:

1. Obstructions: Objects that shouldn’t be in your disposal, such as utensils or small toys, can block the blades and prevent them from rotating, leading to a humming sound when the motor tries to activate. (The Spruce)
2. Electrical Issues: A tripped GFCI outlet or circuit breaker can cause the blades to stop moving, while the motor continues to make a humming noise. This could be due to a short circuit or overheating. (The Spruce)
3. Overheating Motor: The motor itself may overheat if the blades are dull, if there’s an overload of items, or if the motor is faulty. This can lead to a persistent humming noise. (The Spruce)
4. Wear and Tear: As garbage disposals age—they typically last 10 to 15 years—a humming sound might signal a failing motor and indicate it’s time for a replacement. (The Spruce)
5. Non-Jam-Related Humming: Sometimes, the flywheel might turn manually without any jam, but when powered, the unit only hums. This could point to more complex issues within the disposal unit itself. (Quora)

Impact of Foreign Objects

Foreign objects trapped in your garbage disposal can have several impacts:

• Damage to Blades: Sharp objects can nick the blades, dulling them and reducing the efficiency of the disposal.
• Motor Strain: Unyielding items can cause the motor to work harder than it should, potentially leading to overheating.
• Electrical Trips: The motor’s struggle to move jammed blades can trip electrical safety mechanisms, such as GFCI outlets or breakers.
• Unit Lifespan: Regular jams can shorten the overall lifespan of the unit due to increased wear and tear.

It’s crucial to understand and recognize what should not go into a disposal to prevent these scenarios.

Preventing Garbage Disposal Jams

The frustration of a garbage disposal humming and jammed can be avoided by adhering to proper disposal practices and knowing which foods to steer clear of. By following these guidelines, you can prevent jams and extend the life of your garbage disposal.

Careful Disposal Practices

To prevent jams and maintain a functional disposal, it’s important to:

• Run cold water before, during, and after disposal use.
• Feed waste gradually rather than all at once.
• Cut large items into smaller pieces before disposing.
• Allow the disposal to run until grinding is complete and only the sound of the motor and water is heard.

Practicing these steps can significantly reduce the chances of a garbage disposal not working humming scenario.

Foods to Avoid

Certain foods are notorious for causing blockages and should be disposed of in the trash rather than the disposal. The following list includes items that commonly contribute to disposal jams:

Foods to Avoid	Reason
Bones (chicken, fish, meat)	Can damage motor or get stuck in plumbing
Eggshells	Membrane can lead to clogs
Fibrous Vegetables (celery, corn husks)	Can tangle and create blockages
Starchy Foods (pasta, rice, bread)	Expand when wet and cause blockages

Troubleshooting a Humming Disposal

If your garbage disposal is emitting a humming noise, it could be a sign of a jam or an electrical issue. This guide will walk you through the initial steps to troubleshoot a humming disposal, helping you determine whether you can resolve the issue yourself or if professional assistance is needed.

Resetting the Disposal

Often, a simple reset can resolve a humming garbage disposal. If your disposal has stopped working and is emitting a humming noise, it may have overheated or overloaded. Most units have a reset button located on the bottom or side. To reset your disposal:

1. Ensure the disposal switch is in the “OFF” position.
2. Press the reset button firmly until it clicks and remains depressed.
3. Wait a few minutes to allow the unit to cool down.
4. Turn the water on and then turn the disposal on to see if it operates normally.

If the disposal starts to hum again or doesn’t turn on, there might be an issue with the internal mechanics or an electrical problem. For more detailed instructions, check out our guide on how to fix garbage disposal humming.

Checking for Electrical Issues

Electrical problems can also cause your disposal to hum. If resetting the unit does not work, you may need to investigate further:

1. Turn off the disposal at the wall switch.
2. Check your home’s circuit breaker or fuse box to see if the circuit has tripped or a fuse has blown.
3. If the circuit breaker has tripped, reset it and try operating the disposal again.
4. If the problem persists, inspect the GFCI outlet (typically located on the wall or under the sink) and reset it if necessary.

Electrical issues can range from a tripped breaker or GFCI outlet to a short-circuiting connection or a faulty motor. If the disposal blades don’t rotate with a humming sound, it may indicate a tripped GFCI outlet or circuit breaker, likely due to an electrical issue like a short-circuiting connection or overheating (The Spruce).

Other signs that may indicate electrical issues include a disposal that’s humming and leaking, smoking, or not draining (garbage disposal humming and leaking, garbage disposal humming and smoking, garbage disposal humming and not draining). If you notice any of these issues, it’s crucial to switch off the unit immediately to avoid further damage or injury.

If the humming persists after checking the electrical connections and resetting the GFCI, it might be time to seek professional help. An expert technician can provide a thorough diagnosis and repair any complex issues safely and efficiently (garbage disposal humming and stuck).

Resolving a Jammed Disposal

If you find your garbage disposal humming but not working, it’s often an indication that it’s jammed. Resolving a jammed disposal is a common home repair that you can usually handle without the need for a professional plumber.

Clearing Blockages

The first step in addressing a garbage disposal humming and jammed is to identify and clear any blockages. Follow these steps to safely remove items that may be causing the jam:

1. Turn off the power to the disposal at the breaker and wall switch to prevent accidental operation.
2. Shine a flashlight down the disposal to spot the object causing the jam.
3. Using a pair of pliers or tongs, carefully remove the object from the disposal. Never place your hand inside the disposal even when the power is off.
4. Once the object has been removed, check for any remaining debris that could cause further jams.
5. After clearing the disposal, press the reset button typically located on the bottom of the unit. Most newer disposals have an automatic shutoff feature when the motor overheats, which can also cause the unit to hum (The Spruce).

If your disposal is humming and not draining or you notice additional issues like humming and leaking, humming and smoking, or humming and clogged scenarios, you may need to perform further troubleshooting or seek professional help.

Using Allen Wrench to Free Impellers

For instances where the disposal is humming and stuck, using an Allen (hex) wrench can help to free the impellers:

1. Locate the hex socket on the bottom of the disposal unit.
2. Insert the Allen wrench into the socket.
3. Gently move the wrench back and forth to rotate the impeller assembly and loosen the jam.
4. Once you feel the impellers move freely, remove the wrench, turn the power back on, and test the disposal.

It is especially important to ensure all safety precautions are followed during this process to avoid injury or further damage to your disposal system. The correct use of the Allen wrench can effectively resolve issues where the disposal is humming but not spinning, as it helps to realign the impellers and clear obstructions (The Spruce).

By following these steps and understanding how to fix a garbage disposal humming, you can often resolve simple jams on your own. If you’ve tried these methods and continue to experience issues, it may be time to seek out a technician who can provide professional repairs to ensure the longevity and functionality of your disposal.
