Diagnose
Garbage Disposal not working? Common problems and what causes them
Diagnostic fee waived with repair
Most disposal calls are a jam or a tripped reset, not a dead unit — worth a same-visit diagnosis before replacing anything.
Quick answer
Most garbage disposals fail because of a single component, not age. The usual culprits are won't turn on, humming but not spinning, jammed. Most repairs finish in one visit. Replacement is usually only worth it above roughly eight years old or when the repair exceeds half the replacement price.

Garbage Disposal Repair details & coverageDiagnosis
How we diagnose a garbage disposal problem
Every visit starts with a diagnosis, not a guess. Here's what your technician actually checks, in order, before recommending a repair.
- 1
Jam check via reset & hex-key
We check for a jam first using the bottom reset button and the hex-key opening — most dead disposals are simply jammed, not burned out.
- 2
Motor hum vs. silence
A disposal that hums but doesn't spin has power and a jam or a seized motor; one that's completely silent points at the reset, a breaker, or a failed motor — different repairs entirely.
- 3
Leak source
We trace leaks to their actual source — the sink flange, the discharge tube, or the dishwasher inlet connection — since each has a different fix and only one means the unit itself is bad.
- 4
Impeller & flywheel condition
If the jam clears but grinding stays weak or loud, we check the impeller blades and flywheel for wear or a lodged object.
Repair or replace
When replacement is the better call
The working rule is the 50% test: if the repair costs more than half of a comparable new unit, and the appliance is past roughly two-thirds of its expected life, replacement usually wins on total cost of ownership.
Most garbage disposals are built for 10–13 years. A failure at year three is almost always worth repairing. A sealed-system or compressor failure at year twelve usually is not — and we will say so rather than sell you the repair.
Premium built-in units are the exception. A Sub-Zero or Viking unit is worth repairing well past the point where a mass-market appliance would be retired, because replacement runs into five figures once cabinetry work is included.
Questions
Garbage Disposal repair FAQ
Is it worth repairing a garbage disposal?
Repairing a garbage disposal is generally worth it when the repair costs less than half the price of a replacement and the unit is under about eight years old. SOS Appliance Repair diagnoses first and tells you plainly when replacement is the better value.
How long does a garbage disposal repair take?
Most garbage disposal repairs are completed in a single visit lasting 45 to 90 minutes. When a part must be ordered, SOS Appliance Repair schedules the return visit before leaving and the original diagnostic is not charged twice.
What causes a garbage disposal to fail?
The most common garbage disposal faults SOS Appliance Repair sees are: won't turn on, humming but not spinning, jammed, leaking underneath. Most trace back to a single failed component rather than end-of-life, which is why diagnosis before replacement matters.
