Why is the Garbage Disposal Humming?

At NestTenders, we understand that a humming garbage disposal can be more than just a minor annoyance—it can disrupt your daily routine and signal potential plumbing issues. In this article, we'll dive into the common reasons behind this humming sound and offer practical solutions to fix and prevent these issues.

Common Reasons for a Humming Garbage Disposal

 

Jammed Flywheel

The most common cause of a humming garbage disposal is a jammed flywheel. When food particles or hard objects get lodged between the shredder ring and the impellers, the motor struggles to rotate the flywheel, resulting in a humming noise.

 

Overheated Motor

The motor can overheat if the disposal is run for an extended period or is frequently clogged. An overheated motor will often hum but not operate correctly.

 

Faulty Electrical Components

Sometimes, the issue might be electrical, such as faulty wiring or a malfunctioning motor. In these cases, the humming sound is a symptom of an electrical problem.

 

Solutions to Fix a Humming Garbage Disposal

 

Reset the Disposal

Most disposals come with a reset button located at the bottom. If your disposal is humming, turn it off, wait a few minutes to let the motor cool down, and press the reset button.

 

Clearing a Jam

To clear a jam, first, ensure the disposal is off. Use an Allen wrench in the center shaft beneath the disposal or a broom handle from above to gently rotate the flywheel. This movement can help dislodge whatever is causing the jam.

 

Check for Overheating

If the disposal has overheated, give it time to cool down before resetting it. Ensure that you're not running it for too long.

 

Seek Professional Help

If the issue is electrical or if you're uncomfortable attempting repairs, it's best to consult a professional. Tampering with electrical components without proper knowledge can be dangerous.

 

Prevention Tips

 

Regular Cleaning

Regular cleaning can prevent buildup that leads to jams. Ice cubes and coarse salt can help scrub the grinding elements, while citrus peels can help eliminate odors.

 

Avoid Hard Objects

Be mindful of what you put down your disposal. Avoid disposing of hard objects like bones or fruit pits, which can easily jam the disposal.

 

Run Cold Water

Always run cold water when using the disposal. It helps in the smooth grinding of waste and prevents overheating.

 

Routine Maintenance

Routine checks and maintenance by a professional can prevent electrical issues and ensure your disposal runs smoothly.

 

A humming garbage disposal is a common household issue, but it can be easily addressed with the right knowledge. By understanding the causes and following our straightforward solutions and prevention tips, you can ensure your garbage disposal functions efficiently and avoid disruptions to your daily routine.
