Understanding Garbage Disposal Humming

When your garbage disposal starts emitting a humming sound, it’s a signal that something is amiss. Understanding the causes behind this sound can help you address the issue promptly and prevent further damage to the unit.

Causes of Garbage Disposal Humming

A humming noise from your garbage disposal typically indicates that the blades are not turning. This can be the result of a clog, an obstruction, or an overheated motor (The Spruce). Common causes include:

Physical Obstructions: Items like utensils, toys, or other foreign objects can get lodged in the disposal, preventing the blades from rotating.
Motor Related Issues: If the motor is overheated or faulty, it may hum but fail to turn the blades efficiently.
Electrical Problems: A tripped GFCI outlet or circuit breaker could prevent the blades from turning while still allowing the motor to hum.
Jammed Flywheel: The internal flywheel may be jammed, which can be resolved by manually freeing it.

Effects of Smoking Material Disposal

While a garbage disposal is a robust appliance, it is not designed to handle certain materials, including smoking materials such as cigarette butts. Disposing of such items improperly can lead to significant hazards, such as:

Outdoor Fires: In Calgary, improper disposal of smoking materials is the leading cause of outdoor fires, with instances of items like cigarettes smoldering for hours before igniting.
Motor Malfunction: If smoking materials are disposed of in a garbage disposal, they can cause the motor or motor capacitor to malfunction, sometimes resulting in a burning smell or even smoking of the unit (PartSelect).

If your disposal begins to smoke or emit a burning smell, this could be due to a fried circuit or motor, which may require a complete replacement of the unit (Black-Haak). It’s crucial to prevent such issues by following proper usage guidelines and knowing what not to dispose of in your unit.

Troubleshooting Garbage Disposal Humming

If your garbage disposal is emitting a humming sound, it’s signaling that there’s a problem that needs attention. This sound often indicates that the disposal is receiving power but the blades are not turning. Here are ways to troubleshoot and resolve the issue.

Jammed Flywheel Solutions

A common cause for a garbage disposal humming and not working is a jammed flywheel or impeller. Obstructions due to foreign objects like utensils, bones, or other unexpected items can prevent the flywheel from rotating. To fix this:

Turn off the power to the disposal at the electrical service panel.
Unplug the unit for additional safety.
Use the wrench that came with the disposal or an Allen wrench to manually turn the flywheel from the bottom of the unit. Insert the wrench into the flywheel turning hole and rotate back and forth to dislodge any obstruction.
If the wrench method doesn’t work, look into the drain and use needle-nose pliers to remove any visible obstructions.
Once the jam is cleared, rotate the flywheel to ensure it moves freely.
Plug the unit back in and turn the power back on.
Test the disposal to see if it’s working properly.

Remember, if you’re not comfortable performing these steps or if the problem persists, it’s wise to contact a professional plumber for assistance, especially to avoid potential issues like a garbage disposal humming and jammed or garbage disposal humming and stuck.

Resetting the Disposal Unit

If the flywheel isn’t jammed and the disposal is still humming, the unit may need to be reset. This is a common solution when the disposal motor overheats or there’s an electrical anomaly. Here’s how to reset your garbage disposal:

Ensure the disposal switch is in the “OFF” position.
Locate the reset button on the bottom of the disposal unit.
Press the reset button firmly until it clicks and stays in place.
Wait a few minutes to let the disposal cool off if it was overheated.
Turn on the water, then the disposal to test if it’s working correctly.

In cases where the reset doesn’t resolve the humming, the issue might be electrical, such as a tripped GFCI outlet or breaker. Check your service panel to see if the circuit for the disposal has tripped and reset it if necessary.

Dealing with Specific Issues

When faced with a garbage disposal that’s humming, pinpointing the issue is the first step to resolution. Here are two common problems that might be causing your unit to make noise without functioning properly.

Motor Overheating and Humming

An overheated motor is often a culprit for your garbage disposal’s humming sounds. Overheating can stem from a variety of issues, including a malfunctioning motor, dull blades, or inserting inappropriate materials into the disposal. It’s also possible to cause overheating by running the unit continuously without giving it a break (The Spruce).

Symptoms of an overheated disposal may include a persistent humming noise, a smell of smoke, or the unit repeatedly stopping and starting. If you encounter these signs, it’s advisable to cease using the disposal and seek professional assistance. A qualified technician can determine whether you can fix the current unit or need to consider a replacement, particularly if the disposal is older or the issue is recurring.

Tripped GFCI Outlet or Breaker

A tripped GFCI outlet or circuit breaker can also be the reason your garbage disposal motor powers on but the spinning disc doesn’t rotate. This safety mechanism may trip due to electrical problems like a short-circuiting connection, which can be associated with overheating.

If you notice that your garbage disposal is humming but not operating, check to see if the GFCI outlet or breaker has been tripped. You can attempt to reset the GFCI or flip the breaker back on, but if it trips again, it’s an indication of a more severe electrical issue. It’s crucial to have a professional evaluate the problem to ensure safe resolution and avoid potential hazards such as electrocution (Cozy Home Services).

In either case, addressing these specific issues promptly can help mitigate the risk of further damage to your disposal unit and ensure its longevity. Remember, when dealing with electrical components and appliances, safety should always be your top priority.

Signs of Motor Failure

Identifying when your garbage disposal’s motor is failing is key to deciding whether it’s time for a repair or replacement. A humming sound can be a tell-tale sign of motor issues.

Identifying Faulty Motors

A faulty motor in your garbage disposal may exhibit several symptoms that you can identify. The most common sign is a persistent garbage disposal humming noise that occurs when you turn on the unit, but the blades aren’t spinning. This could be due to several issues, including jammed impellers or electrical problems. However, if the humming persists even after troubleshooting jams and resets, it could indicate a motor failure, especially in disposals that are reaching the end of their average lifespan—typically 10 to 15 years.

If the disposal is new and still under warranty, wiring issues or defective parts may be the culprit. It’s essential to have a professional plumber assess the situation—they can determine whether the motor can be fixed or if it’s time to replace the unit.

Potential Replacement Considerations

When a garbage disposal’s motor fails and it’s not feasible to repair it, replacement becomes necessary. Here are some considerations when thinking about replacing your garbage disposal:

Age of the Disposal: If your disposal is older than 10 years, it might be more cost-effective to replace it rather than repair it.
Cost of Repair vs. Replacement: Compare the cost of repairing the existing unit to buying a new one. Sometimes, the price of a new disposal might be similar to the repair costs.
Warranty: Check if your disposal is still under warranty. If so, you may be able to have it repaired or replaced at a reduced cost or for free.
Features: Modern disposals may have features that your old one did not, such as quieter operation or better grinding capabilities.
Safety: Since garbage disposals can cause severe injury, you might want to consider a model with advanced safety features (McCombs Supply).
Efficiency: Newer models are often more energy-efficient and could save you money in the long run.
Installation: Think about whether you will install the new disposal yourself or hire a professional. This will affect your overall cost and timeline.

Before making a decision, it’s advisable to consult with a professional plumber who can provide you with more personalized advice based on your specific situation and needs.

Preventive Maintenance Tips

Maintaining your garbage disposal can prevent issues like garbage disposal humming and smoking and extend its lifespan. By following a few simple guidelines, you can keep your disposal running smoothly and avoid the inconvenience of a malfunctioning unit.

Proper Usage Guidelines

Your garbage disposal is a powerful kitchen tool, but it’s not invincible. To prevent common problems like garbage disposal humming and jammed or garbage disposal humming and stuck, here are some key usage guidelines:

Avoid overloading your disposal with too much waste at once. This can lead to clogs and cause the unit to overheat or jam.
Do not dispose of hard or fibrous materials, such as bones, corn husks, or fruit pits, which can damage the blades or cause a jam.
Never use harsh chemicals or drain cleaners in your disposal, as they can corrode the internal components.
Always run cold water while the disposal is in use. This helps to solidify grease and fat, making it easier for the disposal to break them down effectively.
Keep your hands out of the disposal to prevent injury. Use tools specifically designed for garbage disposals to clear any clogs or jams.

Following these guidelines can help prevent the most common cause of garbage disposal problems, which is “operator error”.

Importance of Cold Water Flushing

Cold water plays a crucial role in the optimal operation of your garbage disposal. Despite common misconceptions, hot water can actually lead to motor overheating and doesn’t aid in keeping the disposal clear. In fact, hot water may contribute to breakdowns over time.

Cold water, on the other hand, has several benefits:

Solidifies grease and fatty waste for easier disposal.
Helps the motor to stay at a safe operating temperature.
Reduces the likelihood of clogged pipes downstream.

Here’s how to properly use cold water with your garbage disposal:

Begin by running cold water before you turn on the disposal.
Continue to run the cold water while you feed waste into the unit.
Keep the cold water running for about 15 seconds after you turn off the disposal to flush any remaining debris through the pipes.

Implementing cold water flushing into your disposal routine can prevent issues like garbage disposal humming and not draining or garbage disposal humming and clogged, ensuring your kitchen remains clean and functional (McCombs Supply).

Proper maintenance can save you the headache of dealing with a malfunctioning garbage disposal.
