Garbage Disposal Jammed in Charleston SC

A garbage disposal that hums when switched on but doesn't actually grind is almost always jammed rather than genuinely broken — the motor is receiving power and trying to turn, but something is physically blocking the grinding plate from rotating.

Before booking a repair visit, it's worth trying two safe, standard steps yourself: first, never put your hand inside the disposal — always switch it off and unplug it or cut power at the breaker first. Most disposals have a small hex-shaped hole on the underside of the unit where an Allen wrench can be inserted to manually rotate the grinding plate and work a jam loose from below.

Second, most disposals have a small red or black reset button on the bottom of the unit that trips similarly to a circuit breaker when the motor overheats from a jam — pressing this after clearing the jam is often all that's needed to get the unit running again.

If those steps don't resolve it, the jam may be caused by something the disposal genuinely can't grind — a stray utensil, bone fragment, or fibrous material like celery or corn husks that's wrapped around the grinding components rather than sitting loosely.

If the disposal doesn't hum at all and shows no response, that points toward an electrical issue rather than a mechanical jam — a tripped breaker, a bad switch, or in rarer cases a failed motor, which is a different repair path than clearing a jam.

Persistent jamming that recurs frequently, even after clearing it, can indicate worn or damaged impeller blades that are no longer grinding effectively, which is a parts repair rather than something you can clear yourself.

Our technicians safely disassemble the unit when needed to remove a jam that can't be cleared from below, and test motor and blade condition if jamming is recurring rather than a one-time event.

The $89 service call fee covers this diagnostic and jam clearing. If the unit needs a part — most commonly the motor or impeller assembly on an older unit — your technician will quote that clearly, and will also tell you honestly if replacement makes more sense than repair on an aging disposal.
