Why Is My Garbage Disposal Not Working?
Understanding common problems can help you decide whether you need a quick fix or professional service.
Humming But Not Spinning
If your garbage disposal hums when you flip the switch but the blades don't spin, something is likely jammed between the impellers and the shredder ring. This is one of the most common garbage disposal problems. While you can try using an Allen wrench in the hex socket on the bottom of the unit to manually rotate the flywheel, a stuck disposal that won't free up needs professional attention to avoid motor burnout.
- Foreign object lodged in grinding chamber
- Impeller plate seized from corrosion
- Motor overheating from prolonged jam
Leaking Garbage Disposal
A leaking garbage disposal can cause water damage to your cabinet and flooring if not addressed quickly. The location of the leak tells us a lot about the problem. Leaks from the top usually mean the sink flange seal has failed. Side leaks often indicate a loose drain connection or dishwasher inlet. Leaks from the bottom of the unit typically signal a failed internal seal, which usually means it's time for a replacement.
- Top leak: worn putty or flange gasket
- Side leak: loose connection or cracked hose
- Bottom leak: internal seal failure (replace unit)
Slow Draining
If water sits in the sink long after running the disposal, there may be a partial clog in the drain line, or the disposal's grinding components may be worn and not breaking food down finely enough. Built-up grease, fibrous foods like celery, or starchy foods like pasta and rice can accumulate and restrict water flow over time.
- Partial clog in the discharge pipe
- Worn grinding components
- Grease or starch buildup in drain line
Unusual Noises
Loud grinding, rattling, or screeching noises from your garbage disposal typically indicate a foreign object in the chamber, loose mounting hardware, or worn-out internal components. A metallic scraping sound often means a utensil or hard object has fallen in. Persistent rattling may indicate the mounting assembly has loosened, causing the unit to vibrate against the sink.
- Foreign object like a utensil in the chamber
- Loose mounting bracket or screws
- Worn bearings or impeller components

Frequently Asked Questions
Get answers to common questions about garbage disposal repair and installation.
How much does garbage disposal installation cost?
Garbage disposal installation cost depends on the unit you choose and whether it's a replacement or a first-time install. A straightforward replacement typically costs less since the plumbing and electrical connections are already in place. First-time installations may require additional work for wiring and drain modifications. We provide free estimates with upfront pricing so there are no surprises.
Why is my garbage disposal not working?
There are several common reasons your garbage disposal may not be working. If it hums but doesn't spin, it's likely jammed—a foreign object may be stuck between the impellers and the shredder ring. If it doesn't make any sound at all, check the reset button on the bottom of the unit and make sure it's plugged in. A tripped circuit breaker is another common culprit. If these quick fixes don't help, the motor or internal components may need professional repair.
How long does garbage disposal repair take?
Most garbage disposal repairs can be completed in under an hour. Common fixes like clearing a jam, replacing a splash guard, or tightening connections are straightforward. More complex repairs involving electrical issues or internal component replacement may take 1-2 hours. Our technicians arrive with fully stocked trucks to handle most repairs in a single visit.
Should I repair or replace my garbage disposal?
If your garbage disposal is less than 5 years old and has a minor issue like a jam or a simple leak at a connection point, repair usually makes sense. However, if the unit is over 8 years old, leaking from the bottom (indicating a failed internal seal), or requires frequent repairs, replacement is typically more cost-effective. We'll give you an honest recommendation based on your specific situation.
What size garbage disposal do I need?
For most households, a 1/2 HP disposal handles light use (1-2 people), a 3/4 HP unit works well for average families (3-4 people), and a 1 HP model is ideal for heavy use or larger families. We also recommend continuous-feed models for convenience and batch-feed models for households with young children for added safety. Our team will recommend the right size based on your usage and household needs.
