Reasons For A Humming Garbage Disposal

A humming garbage disposal may indicate several issues. It could be due to a jammed impeller, a faulty motor, or a clogged drain pipe. Identifying and resolving these problems can help restore your garbage disposal to its normal functioning.

Having a garbage disposal that hums but doesn’t work can be a frustrating experience. It not only disrupts your daily routine but can also lead to a buildup of food waste. Understanding the reasons behind humming garbage disposal can help you troubleshoot the issue effectively.

Jammed Impellers

When the garbage disposal is humming but not functioning, jammed impellers could be the culprit. Impellers are the rotating blades that break down food waste. If they become jammed, the disposal may emit a humming sound but won’t grind food effectively.

Common causes of jammed impellers include excessive food scraps, foreign objects, or a lack of regular maintenance.

Faulty Motor

Another potential cause of a humming garbage disposal is a faulty motor.

The motor is the core component responsible for powering the impellers and grinding food waste. When the motor malfunctions, the disposal might emit a humming noise without effectively disposing of the waste. This could be due to electrical issues, mechanical faults, or general wear and tear.

Understanding these reasons for humming garbage disposal can help you identify and resolve the issue effectively. By addressing jammed impellers or a faulty motor, you can restore the functionality of your disposal and prevent further disruptions to your kitchen routine.

Common Mistakes To Avoid

When your garbage disposal is humming but not working, it can be frustrating and inconvenient.

However, before you call a plumber, there are common mistakes that homeowners often make, which can cause the issue.

By avoiding these missteps, you can potentially resolve the problem without the need for expensive repairs. Below are some common mistakes to avoid when dealing with a garbage disposal that is humming but not working.

Using Harsh Chemicals

Many people resort to pouring harsh chemical drain cleaners down their garbage disposal when they encounter issues.

However, this can be detrimental to the disposal unit. The strong chemicals can damage the internal components and contribute to further malfunctions. Rather than using chemicals, consider alternative methods for addressing the problem, such as manually clearing any clogs or utilizing natural cleaning solutions.

Disposing Of Non-food Items

Another common mistake is disposing of non-food items in the garbage disposal. This can include materials such as plastic, metal, glass, and fibrous materials. These items can cause blockages and damage the disposal’s blades and motor.

It’s essential to only put biodegradable food waste into the unit and refrain from flushing non-food items down the drain.

Neglecting Maintenance

Neglecting regular maintenance is a crucial mistake that can lead to a humming garbage disposal. Over time, food particles and debris can accumulate within the unit, leading to clogs and reduced functionality.

By performing routine maintenance, such as cleaning the disposal and ensuring the blades are sharp, you can prevent potential issues from arising.

Calling A Professional For Help

If your garbage disposal is humming but not working, it’s best to call a professional for help. Ignoring the issue can lead to further damage and costly repairs. Addressing the problem promptly ensures a smoothly functioning disposal system.

When Diy Solutions Don’t Work

When your kitchen sink is clogged and your garbage disposal is malfunctioning, it’s time to call in the professionals. While it can be tempting to continue troubleshooting on your own, keep in mind that a professional plumber has the expertise and tools needed to diagnose and fix the problem efficiently.

Before reaching out to a plumber, it’s important to exhaust all the DIY methods you can find. The first step is to check if there’s a jam or blockage in the disposal.

Use an Allen wrench to turn the impeller from the bottom and free up any obstructions. If that doesn’t work, try pressing the red reset button located at the bottom of the disposal unit. This might help reset the motor and restore its normal function.

First and foremost, prioritize plumbers who have experience specifically with garbage disposal repairs. While many plumbers offer a wide range of services, focusing on professionals who specialize in this area ensures that you receive the most accurate and efficient assistance possible.

Secondly, read online reviews and testimonials from previous customers. This can give you insight into their level of professionalism, expertise, and customer satisfaction. Look for plumbers with consistently positive reviews, as this indicates their reliability and commitment to quality service.

Furthermore, consider asking friends, family, or neighbors for recommendations. Personal referrals are a valuable source of information as they come from individuals who have had firsthand experience with the plumber’s service. If someone you trust has had a positive experience, likely, you will too.

Once you have a shortlist of potential plumbers, contact each one and ask for a detailed estimate of the repair work needed. Compare the estimates, taking into account factors like price, warranty, and timeline. This way, you can make an informed decision and choose the plumber who meets your needs and budget.
