That annoying hum coming from your garbage disposal? It’s a surprisingly common issue, and thankfully, usually an easy fix. Let’s walk through some simple steps to get it running smoothly again.
Powering Down: Safety First
Before you do anything else, turn off the power to the disposal. Don’t just unplug it; go straight to your electrical panel and flip the breaker switch that controls the disposal. This guarantees it’s completely off and you’re safe.
Investigating the Hum: What’s Causing the Buzz?
Grab a flashlight and carefully peek into the disposal chamber. Anything stuck? A small bone, silverware, or even built-up food debris can cause that irritating buzz. If you see something, use tongs or pliers to carefully remove it. Never reach your hand into the disposal.
Reset & Rotation: Simple Solutions
Many disposals have a little red reset button located on the bottom. Give it a firm press. If you don’t see a button, look for a small hole near the bottom center. This is where an Allen wrench (sometimes included with the disposal) comes in. Insert the wrench and try to rotate the motor shaft back and forth gently to free a stuck motor. Some models may also allow you to insert a broom handle (carefully!) from above to nudge the impellers.
Power Up & Test: Listen Carefully
Think you’ve found the culprit? Double-check that the circuit breaker hasn’t tripped and flip it back on if necessary. Now, with cold water running, turn on the disposal briefly. Listen carefully. Is it still humming?
Still Buzzing? When to Call a Pro
If the disposal is still humming after these steps, the problem might be more complex, like a frozen motor or internal wiring issues. These are best left to a qualified plumber or appliance repair technician. Don’t risk further damage or injury.
Preventing Future Buzzes: Keeping Your Disposal Happy
Here are some tips to prevent future buzzing:
- Avoid Hard Items: Bones, fruit pits, shellfish shells—toss these in the trash.
- Chop Fibrous Foods: Stringy vegetables like celery? Chop them into smaller pieces.
- No Grease: Wipe greasy pans before washing.
- Cold Water is Key: Run cold water before, during, and after using the disposal.
- Citrus Fresh (Use with Caution): Some experts recommend citrus peels, but they can contribute to clogs, especially in older models. Use sparingly and always with cold water.
- Regular Cleaning: Baking soda and vinegar, or ice cubes and rock salt, can help keep your disposal clean.
Advanced Troubleshooting: Beyond the Basics
If you’ve tried everything and the humming continues or you smell burning, definitely call a professional.
Garbage Disposal FAQs: Quick Answers
| Question | Answer |
|---|---|
| How do I clean my disposal? | Baking soda and vinegar, ice cubes and rock salt. |
| What if the reset button doesn’t work? | Double-check circuit breaker, then try rotating blades manually. |
| When should I replace my disposal? | Constant jams, leaks, unusual noises, or burning smells signal it might be time. |
Why is My Garbage Disposal Humming But Not Grinding?
A humming disposal that isn’t grinding probably suggests a jam. The motor is trying to turn the impellers (the “spinny things” that grind food), but something is blocking them.
Understanding the Buzz: A Look Inside
Your disposal grinds food scraps using impellers. When something gets stuck, the impellers can’t spin, causing the humming.

Preventing Problems: What NOT to Put Down There
(Visual: Chart or infographic listing items to avoid)
- Hard Items: Bones, fruit pits, etc.
- Fibrous Foods: Celery, corn husks, etc.
- Grease & Oil: These will clog your pipes over time.
- Starchy/Expandable Foods: Pasta, rice, potatoes.
- Non-Food Items: Absolutely never!
Advanced Issues and Repairs: Knowing When to Call a Pro
Persistent humming, burning smells, or leaks? Call a plumber. While some experts believe regular cleaning can extend a disposal’s life, ongoing research suggests that certain commercial cleaners might actually be harmful due to their harsh chemicals.
Additional Tips and Considerations:
- Running cold water during and after grinding helps flush away debris and solidifies any grease.
- Grinding ice cubes can sometimes help sharpen the blades and dislodge small particles.
- Some studies suggest that the average lifespan of a garbage disposal is around 10-12 years. However, with proper care and maintenance, it may last longer.
- Disposal warranties vary by manufacturer. Check your disposal’s documentation or the manufacturer’s website for information on warranty coverage.
