Always turn off power at the wall switch (and ideally the breaker) before reaching into the unit. Never put your hand into the grinding chamber, even when powered off.
Humming But Not Spinning
Usually indicates the impeller is jammed, not that the motor has failed. Often resolved with the manual reset tool (an Allen wrench, often included) turned in the bottom center hole to free the jam, followed by the reset button.
Completely Dead Disposal
No sound at all often points to a tripped reset button, a tripped breaker, or in some cases a failed motor. Check the reset button (usually on the bottom of the unit) and your electrical panel before assuming it needs replacement.
Symptom / Safe Check / Likely Repair
| Symptom | Safe Check | Likely Repair |
|---|---|---|
| Humming, not spinning | Manual reset tool, then reset button | Clear jam |
| No sound at all | Reset button, then breaker | Reset, or motor assessment if unresolved |
| Leak at sink flange | Visual check under sink (power off) | Reseal or replace flange gasket |
| Dishwasher not draining | Check knockout plug was removed | Reconnect/clear dishwasher line |
What Not to Put in a Disposal
Repair vs. Replacement
| Factor | Favors Repair | Favors Replacement |
|---|---|---|
| Issue | Simple jam, reset needed | Motor failure, body leak |
| Age | Newer unit | Older unit near typical end of service life |
| Repeated failures | First occurrence | Recurring jams or resets needed |
Replacement Selection Checklist

- Compatibility with your existing sink/dishwasher setup
Safety Rules
- Always power off at the wall switch (and ideally breaker) first
- Never put a hand into the disposal chamber — use tongs or the crank tool

Frequently Asked Questions
My disposal just hums — do I need a new one?
Not necessarily — this is often a jam, fixable with the manual reset tool and reset button rather than a sign the unit has failed.
Is it safe to reach into the disposal to clear a jam?
Never with power on, and never with your hand — use the manual crank tool and tongs, with the unit switched off first.
How long do garbage disposals typically last?
Service life varies widely with unit quality, usage, and maintenance. Repeated jams, leaks, or motor problems can signal replacement is becoming more practical than repair.
Can any plumber install a disposal, or is it electrical work too?
A disposal involves plumbing connections and a power connection. Describe the current connection when requesting service.
