Garbage Disposal Reset Button Not Working – Fix It Now
1. Disposal Is Still Jammed (Most Common Cause)
A jam keeps the motor stalled and prevents the reset button from latching — the overload protector will simply trip again the moment you press it. You must clear the jam first.
- Turn off the wall switch and unplug the disposal under the sink (or shut off the breaker).
- Look under the unit for the hex-key socket in the center of the bottom of the disposal.
- Insert a 1/4-inch hex (Allen) wrench and work it back and forth until the grinding plate spins freely.
- Use tongs — never your fingers — to remove any debris from the grinding chamber.
- Restore power, wait 10 minutes, then press the reset button firmly until you feel it click.
- Run cold water and turn the unit on to test.
2. Motor Needs More Time to Cool Down
The thermal overload protector cuts power to protect the motor from heat damage; the reset button won’t stay in until the motor has cooled sufficiently. This is especially common after prolonged or heavy use.
- Turn off the disposal and leave it completely off for at least 15–30 minutes.
- Make sure the area under the sink has reasonable airflow — open the cabinet doors if needed.
- After cooling, press the reset button firmly until you hear or feel a definite click.
- Run cold water, restore power, and test the unit.
3. Garbage Disposal Reset Button Not Working Due to a Worn Reset Button / Thermal Overload Switch
After years of use, the reset button’s internal spring or the thermal overload switch can wear out, causing it to feel mushy or refuse to latch even when the motor is cool and jam-free.
- Unplug the disposal and place a bucket under the unit in case of residual water.
- Press the button and feel for a firm, distinct click — if it feels loose, depressed, or spongy, the switch is likely faulty.
- Order a compatible replacement reset button / thermal overload switch for your disposal model.
- With the unit unplugged, unscrew the bottom cover plate and locate the overload switch assembly.
- Disconnect the two wires from the old switch (photograph the connections first), remove the retaining nut, and swap in the new switch.
- Reassemble, restore power, and test.
4. Tripped Circuit Breaker or Dead Outlet
If the disposal has no power at all, the reset button can’t function — the unit may appear completely dead rather than humming or buzzing. A tripped breaker or a faulty outlet is often overlooked.
- Check the electrical panel for a tripped breaker labeled “disposal” or “kitchen.” Reset it if needed.
- Plug a lamp or phone charger into the same outlet under the sink to confirm the outlet is live.
- If the outlet is dead but the breaker is on, the outlet itself may have failed — test or replace it.
- If the disposal is wired directly (hardwired), check for a tripped GFCI outlet nearby; press its “Reset” button.
- Once power is confirmed, press the disposal’s reset button and test normally.
5. Faulty On/Off Wall Switch
A defective wall switch can mimic a reset-button problem by preventing the disposal from receiving a start signal even after the reset button has been successfully latched.
- With the disposal plugged in and the reset button clicked in, carefully bypass the wall switch by temporarily using a short jumper wire across the switch terminals (if you are comfortable working with wiring — otherwise call a pro).
- Alternatively, use a non-contact voltage tester to confirm the switch is sending power when flipped on.
- If the disposal runs with the switch bypassed, replace the wall switch.
6. Burned-Out Motor
A motor that has seized or burned out will cause the thermal overload to trip immediately and repeatedly, making it appear as though the reset button simply will not stay in. This is the least common but most serious cause.
- Clear any jam (see Cause 1) and allow 30 minutes of cooling time.
- Plug in the unit, press reset, and flip the switch. If you hear nothing — no hum, no buzz — the motor may be dead.
- If the unit hums but won’t spin even after jam clearing, the motor windings are likely seized.
- For disposals under 5 years old, check the manufacturer’s warranty before purchasing parts. See InSinkErator’s official support page for warranty and manual resources (applies broadly as an industry reference).
- If out of warranty, replacing the entire disposal unit is usually more cost-effective than a motor replacement.
Frequently asked questions
Why does my garbage disposal reset button keep popping out right away?
If the reset button pops back out immediately after you press it, the motor is still overloaded or the jam hasn’t been fully cleared. Work the hex wrench until the grinding plate rotates freely in both directions, remove all debris, and give the motor at least 15–30 minutes to cool completely before trying again.
Where exactly is the reset button on a garbage disposal?
The reset button is located on the bottom of the disposal unit, usually in the center or slightly toward one side. It is a small, square or round button — typically red or black — that protrudes slightly when the overload has tripped and needs to be pressed back in.
Can I run my garbage disposal without the reset button working?
No. The reset button is part of the thermal overload safety circuit; the disposal will not operate unless the button is properly latched in. Attempting to bypass it is dangerous and could damage the motor or create a fire or shock hazard.
How long does a garbage disposal reset button typically last?
The reset button and its internal thermal overload switch can last the life of the unit — 8 to 15 years — under normal use. Frequent overloading, jamming, or running the disposal dry significantly shortens the life of the switch and may require early replacement.
