Causes and solutions of garbage disposal humming

Garbage disposal humming is a convenient appliance in any kitchen.

However, there may come a time when you notice your garbage disposal humming and not functioning properly.

In this article, we will explore the common causes of garbage disposal humming and provide solutions to fix the issue.

Common causes of a garbage disposal humming?

One of the most common causes of a garbage disposal humming is jammed blades.

Over time, food particles and debris can get stuck in the blades and prevent them from rotating smoothly.

This can result in a humming sound when you turn on the disposal.

Another cause of a humming garbage disposal is a clogged disposal.

If there is a buildup of food waste or other materials in the disposal, it can obstruct the blades and cause the humming noise.

Additionally, a tripped breaker can also cause your garbage disposal to hum.

If the circuit breaker that powers the disposal is tripped, the unit may not receive enough power to function properly, resulting in a humming sound.

How do you fix garbage disposal humming?

If you encounter a garbage disposal humming, there are several steps you can take to fix the issue:

  • First, you can try resetting the disposal.

Locate the reset button on the bottom of the unit and press it to reset the motor.

This can often resolve the humming problem.

  • Another step to fix a garbage disposal humming is to check for foreign objects.

Turn off the disposal and use a flashlight to inspect the grinding chamber.

Remove any objects that you find, such as utensils or large pieces of food, that may be causing the obstruction.

  • Additionally, you can test the flywheel to ensure it rotates freely.

Use a wooden dowel or pliers to manually turn the flywheel. If it rotates smoothly, the humming noise may be resolved.

If not, further troubleshooting may be required.

Why is your garbage disposal humming but not turning?

If your garbage disposal is humming but not turning, there could be several reasons for this issue. One possibility is a lack of power to the unit.

Check the circuit breaker socket and ensure it is in the correct position.

If the breaker is tripped, try flipping it back on to restore power to the disposal.

Another potential issue could be with the bottom of the unit. The garbage disposal may be jammed or obstructed by debris, preventing the blades from turning.

In this case, you may need to remove the disposal and inspect the bottom for any blockages or damage.

It is also important to check if the switch for the garbage disposal has been flipped off.

Sometimes, a simple flip of the switch can solve the humming but not turning problem.

When should you call a plumber for a garbage disposal humming?

While there are several DIY solutions for a garbage disposal humming, there are instances when it is best to call a plumber.

 If you have attempted to fix the disposal and it continues to hum, or if you hear unusual noises or grinding sounds, it may be a sign of a more serious issue that requires professional attention.

Additionally, if you find that your garbage disposal is in need of repair or replacement, it is recommended to seek the expertise of a plumber.

They can assess the situation and provide the necessary repairs or recommend a new garbage disposal unit if needed.

How to unclog your garbage disposal

If you’re facing a garbage disposal humming, there are several troubleshooting steps you can take to resolve the issue.

Firstly, if your garbage disposal doesn’t turn on but makes a humming noise, it could indicate a problem with the disposal blades.

Turn off the power to the unit and use an Allen wrench to manually rotate the disposal blades at the bottom of the garbage disposal.

Move the wrench back and forth to dislodge any obstructions that may be causing the humming.

If the garbage disposal is still humming and not turning, check the circuit breaker.

A tripped breaker can cause the disposal to make a humming sound without functioning.

 Locate the breaker box and see if the disposal’s breaker has been tripped. If so, reset it and turn on the power.

In some cases, a garbage disposal humming may indicate a jam.

Ensure the power is turned off, then insert the Allen wrench into the hole at the bottom of the disposal.

Use it to manually rotate the disposal and break free any trapped objects or debris.

Once cleared, hit the reset button, turn on the power, and try running the disposal again.

If these troubleshooting steps don’t resolve the humming noise, it might be time to consider garbage disposal repair or replacement.

You can call a plumber for assistance or opt for a new garbage disposal if the current one is beyond repair.

Remember to keep your garbage disposal clean and avoid putting hard or fibrous items into it to prevent future jams and humming problems.

Tips to prevent your garbage disposal humming

Preventing your garbage disposal from humming in the first place can save you from the hassle of dealing with a malfunctioning unit.

Here are some tips to follow:

  1. Keep your garbage disposal clean by running water down the drain for a few seconds after each use. This helps to flush away any food particles and prevent them from accumulating and causing clogs.
  2. Avoid putting certain items in the disposal, such as bones, eggshells, coffee grounds, and fibrous vegetables. These materials can damage the disposal blades or cause clogs.
  3. Regularly grind waste in the disposal to prevent build-up. By using the disposal regularly, you can help keep the blades clean and prevent them from jamming or clogging.
