The Short Answer
If it hums but won’t spin, it’s jammed — turn it off and free the flywheel with the hex wrench in the bottom socket. If it’s completely silent, press the red reset button on the underside and check the switch and breaker. Those two free fixes revive most “dead” garburators. Never put your hand inside — clear jams with a wrench or tongs only. Re-jamming, no power after reset, or a leak means call a technician.
Two Free Fixes First
Before writing off a garburator, check the two things that fix it for free — both on the underside of the unit. The first is the reset button, a small red button that pops out when the motor overloads or overheats, cutting all power and making the unit seem dead. The second is the hex-wrench socket, which lets you manually turn the flywheel to break a jam. Between them, they revive a remarkable share of “broken” disposals in about two minutes.
The Symptom Table
| Symptom | Likely Cause | What to Do |
|---|---|---|
| Hums but won’t spin | Jammed impellers against the grind ring | Free the jam with the hex wrench in the bottom socket, then hit reset |
| Silent — no sound at all | Tripped reset button, failed switch, or lost power | Press the red reset button underneath; check the switch and breaker |
| Trips off mid-use | Overload from a jam or an overheating motor | Clear the jam and let it cool; repeated tripping means a technician |
| Grinding / rattling noise | A foreign object — a bottle cap, bone, or utensil | Power off, remove the object; worn impellers mean replacement |
| Runs but won’t drain | A clog in the unit or the trap below | Clear the disposal and P-trap; persistent backup needs a look |
Freeing a Jam Safely
A hum with no spin is the classic jam. The safe sequence: switch the unit off at the wall and the breaker; look down into the chamber with a flashlight and remove any visible object with tongs or pliers (never fingers); then find the hex/Allen wrench socket in the centre of the unit's underside, insert the wrench, and rock it firmly back and forth until the flywheel turns freely. Restore power, press the reset button, and test with cold water running. If it frees and runs, you are done.
“The reset button and the little hex wrench fix more disposals than any part we carry — most 'dead' units just tripped and jammed.”
Field note — The Technician Team
When to Call a Technician
Book the visit if the unit re-jams right after clearing, stays silent after a reset with confirmed power, trips repeatedly, leaks, or grinds with a worn, rattling sound. Those point to a failing motor, worn impellers, or a cracked body — and on an older unit, replacement is usually the smarter spend than repair. Our garburator repair team in Sherwood Park clears stubborn jams, replaces worn units, and quotes repair-versus-replace honestly. And keeping it fed right — per our cleaning and care guide — prevents most jams in the first place.
Not-Working Questions, Answered
Why does my garburator hum but not turn?
The motor has power but the grinding plate is jammed — usually a bone, pit, utensil, or fibrous scrap wedged against the impellers. Turn it off, insert the small hex (Allen) wrench into the socket on the underside of the unit, and work it back and forth to free the flywheel; then press the reset button and test with cold water running. If it will not free or re-jams, call a technician — do not force it.
Where is the reset button on a garburator?
On the underside of the unit, in the centre — a small red (sometimes black) button. When a garburator overloads or overheats it trips this button and goes completely silent. Once the unit has cooled and any jam is cleared, press it firmly back in; that alone revives a large share of "dead" disposals at no cost.
Is it safe to reach into a garburator to clear a jam?
Never reach in with your hand, even when it seems off. Always cut the power at the switch or breaker first, and clear jams from the bottom with the hex wrench or from the top with tongs or pliers — never fingers. A garburator that starts unexpectedly with a hand inside causes serious injuries, which is exactly what this rule prevents.
