A garbage disposal that hums but will not spin, leaks from the bottom, or has stopped working entirely is one of the most common kitchen calls we get, and most issues trace back to a jam or a worn seal rather than a dead motor.
Common Reasons Disposals Fail In Altadena Kitchens
Fibrous food waste and grease are the most common causes of a jammed or clogged disposal, and hard water mineral buildup on the internal components can add to wear over time in homes across Altadena's mutual water company service areas.
Many disposals in older Altadena homes are original to a prior kitchen remodel and are now well past a typical 8 to 12 year service life, which is often the real reason a unit finally stops resetting.
A disposal installed during an Eaton Fire rebuild's kitchen buildout starts fresh, but an existing unit that survived a rebuild's plumbing work is worth having checked, since a temporary water shutoff during construction can sometimes let debris settle inside an idle unit.
Common Garbage Disposal Problems
Humming But Not Spinning
Usually a jam against the impeller blades, fixable by clearing the obstruction and resetting the unit.
Leaking From The Bottom
Typically a worn internal seal, which usually means replacement rather than repair on most residential units.
No Power At All
Can be a tripped reset button, a tripped breaker, or a failed motor depending on what else is affected.
Persistent Odor
Often trapped food debris in the splash guard or lower chamber rather than a mechanical problem.

How We Diagnose It
Most jams are cleared using the disposal's own hex wrench port from underneath, after confirming the unit is unplugged for safety, rather than assuming a motor failure.
A unit that hums but does not spin even after clearing a jam usually points to a failed motor bearing, which is typically a sign to replace rather than repair given the age of most units by that point.
Repair Or Replace
Usually Repairable
A jam, a tripped reset, or a loose mounting connection on a unit under about 8 years old.
Usually Replace
A leaking seal, a failed motor, or any unit already past 8 to 12 years of service.
Sizing For Replacement
Household size and typical food waste volume determine whether a standard or higher horsepower unit makes sense.
What Affects The Cost Of Garbage Disposal Repair & Installation
Scope Of The Problem
A straightforward, isolated repair costs less than a job involving multiple fixtures or a harder-to-diagnose root cause.
Parts & Materials
Fixture quality, pipe material, and whether a part needs to be special-ordered all factor into the final price.
Access & Location
A repair behind a finished wall, under a slab, or in a hard-to-reach crawlspace takes longer than one with open access.
Timing
Standard daytime scheduling costs less than an after-hours or weekend emergency dispatch.
Homeowner's insurance often covers sudden, accidental damage like a burst pipe, but typically does not cover gradual wear, an aging part failing on its own, or deferred maintenance. Check your specific policy for what it actually covers before assuming either way.
These factors explain why prices vary. For your exact number, call (626) 898-6169 and describe what you're seeing, we'll give you a flat price before any work begins.
Common Questions
Why does my disposal hum but not spin?
This almost always means something is jammed against the impeller blades. It can usually be cleared without replacing the unit.
Is it worth repairing an old garbage disposal?
If it is already past 8 to 12 years old and showing a leak or motor issue, replacement is usually more cost-effective than repair.
What should never go down a garbage disposal?
Fibrous vegetable scraps, grease, coffee grounds, and bones are common causes of jams and premature wear, even on units built to handle food waste.
How long does disposal replacement take?
Most replacements are completed in under an hour when the new unit matches the existing mounting and electrical setup.
Can a disposal be repaired instead of replaced if it is leaking?
A leak from a worn internal seal is usually not cost-effective to repair on most residential units, since the labor involved often costs close to a new unit.
Before We Arrive
- Never put your hand inside a disposal, even when it is unplugged, to check for a jam. Use tongs or the hex wrench port from underneath instead.
- Try pressing the red reset button on the bottom of the unit once before calling, since a simple trip is a common and quick fix.
- Note whether the unit makes any sound at all when switched on, since a completely silent unit points to a different problem than one that hums.
Related Services
Drain Cleaning & Unclogging: If the sink drains slowly even with the disposal working properly, that points to a separate clog our drain cleaning service handles.
Faucet & Sink Repair: A leak under the sink near the disposal is sometimes the supply line or faucet connection rather than the disposal itself, which our faucet and sink repair service can rule out.
Most garbage disposal problems are a jam or a worn seal rather than a dead unit. We confirm which one it is before recommending a repair or a replacement sized to your kitchen.
