If your garbage disposal suddenly goes quiet, a small button on the unit may be the reason it stopped. That button can bring the motor back after an overload, but pressing it without fixing the cause may only make the disposal shut off again. Here’s what the reset button does, when to use it, and how to troubleshoot safely.

What the Garbage Disposal Reset Button Does
The reset button is a safety feature built into many garbage disposals. It’s usually a small red or black button on the underside of the unit, though its location and color vary by model. If the motor gets too hot or draws too much electrical current, an internal overload protector can switch the disposal off. The reset button lets you restore power after the motor has cooled and the problem has been addressed.
Think of it as a protective cutoff, not an on-off switch or a repair button. It helps prevent damage from overheating, but it doesn’t remove a jam or fix a faulty electrical connection. If something is still stopping the motor, the reset may trip again as soon as you turn the disposal on.
Why a Garbage Disposal Trips Its Reset
A disposal’s motor has to work harder when something blocks the grinding parts. A jam can cause the motor to draw more current and heat up. The overload protector then cuts power before the motor gets too hot.
Common causes include:
- A jam: A hard object, fibrous food, or other debris may be wedged between the grinding plate and the disposal wall.
- A heavy load: Pushing in too much food at once can make the motor work harder than usual.
- Repeated use: Running the disposal for a long time without a break can cause it to overheat.
- An electrical interruption: A tripped circuit breaker or GFCI outlet can also stop the unit, although that’s separate from the disposal’s reset button.
- A developing fault: A worn motor, damaged wiring, or another internal problem can cause repeated shutdowns.
A single trip after an obvious jam or unusually heavy use may be a one-off. If the reset trips repeatedly during normal use, treat that as a warning rather than a nuisance. The underlying cause needs attention.
Where to Find the Reset Button
Look beneath the sink at the bottom of the disposal. The reset button is often a small button near the center or edge of the housing. You may need a flashlight to spot it. Some models place it in a slightly different position, so check the owner’s manual if you can’t find it.
Not every model looks the same. If your disposal doesn’t have a visible reset button, don’t pry at the housing or try to take the unit apart. Check the manufacturer’s instructions, and remember that the circuit breaker or GFCI may be what needs resetting instead.
How to Reset a Garbage Disposal Safely
Before you press the button, make sure the disposal is switched off. If there’s a jam, resetting the unit while the motor is still blocked can make it trip again. It’s also important to keep your hands out of the disposal opening—even when the unit appears to be off.
- Turn off the disposal. Switch it off at the wall or counter switch. If you’ll be reaching under the sink to inspect the unit, switch off its circuit breaker too. For a plug-in model, unplug it when you can do so safely.
- Check for an obvious cause. Use a flashlight to look into the sink opening. Don’t put your hand inside. If you see a loose object near the opening, remove it with tongs or pliers only after confirming the disposal has no power.
- Wait for the motor to cool. Give it at least 10 minutes, or longer if the unit feels warm. The overload protector may not reset until the motor cools down.
- Press the reset button. Push the button on the underside of the disposal. If it won’t stay in, wait a little longer and try once more. Don’t force it.
- Restore power and test briefly. Turn the breaker or switch back on. Run cold water, then switch on the disposal for a few seconds. If it runs normally, keep the water flowing briefly as the waste clears.
If the disposal hums but doesn’t grind, turn it off right away. A hum often means the motor is receiving power but the grinding parts may still be stuck. Continuing to run it can overheat the motor and trip the reset again.
What to Do If the Disposal Is Jammed
Turn off power at the switch and circuit breaker before trying to clear a jam. Never rely on the wall switch alone if you’ll be working near the grinding chamber. The blades and impellers aren’t sharp like a knife, but the mechanism can still cause a serious injury if it starts unexpectedly.
Some disposals have a socket on the bottom for a hex wrench or disposal wrench. If your model has one, use the tool specified by the manufacturer to gently turn the motor shaft back and forth. This can help free a jam without reaching into the unit. Other models may have a different method, so check the manual first. Don’t force the wrench if the mechanism won’t move.
Once you think the jam is clear, remove any loose debris with tongs or pliers—never your fingers. Then press the reset button, restore power, run cold water, and test the disposal briefly. If it remains stuck, makes an unusual noise, leaks, or trips again, stop and contact a qualified repair professional.
Reset Button vs. Circuit Breaker vs. GFCI
These controls can all interrupt power, but they do different jobs. Checking which one has tripped can help you avoid pressing the wrong button or missing a larger electrical issue.
| Control | Where to find it | What it does | What to try |
|---|---|---|---|
| Disposal reset button | Usually on the bottom of the disposal | Restores the unit after its overload protector cuts power | Let the motor cool, clear any jam safely, then press the button |
| Circuit breaker | In your home’s electrical panel | Shuts off power to a circuit when it detects an overload or fault | Switch it fully off, then back on once; if it trips again, stop and get help |
| GFCI outlet or button | On a nearby outlet or another GFCI outlet protecting that circuit | Cuts power when it detects a possible electrical current leak | Press reset on the GFCI only after checking for obvious moisture or damage |
If the breaker trips repeatedly, don’t keep switching it back on. Repeated trips can point to an electrical fault or a motor problem, and the circuit should be checked by a qualified electrician or appliance professional.
Signs the Reset Button Isn’t the Real Problem
A reset button is useful for a temporary overload, but certain symptoms suggest the disposal needs more than a reset:
- The button trips every time you switch on the unit. A jam may still be present, or the motor could be failing.
- The breaker trips repeatedly. This can indicate an overload or electrical fault. Don’t keep resetting it.
- The disposal is completely silent. Check the power switch, breaker, and GFCI. If power is available but the unit stays silent, it may need service.
- There’s a burning smell, smoke, or unusual heat. Turn it off at the breaker and arrange professional inspection.
- The unit leaks or makes grinding, rattling, or squealing noises. A reset won’t fix a leak or worn parts.
When in doubt, switch off the power and call a professional. That’s especially wise if you’re not comfortable working around electrical appliances or can’t identify the cause of the problem.
How to Reduce Future Reset Trips
Good habits can reduce jams and overheating. Feed food waste in gradually instead of pushing in a large pile all at once. Run a steady flow of cold water while the disposal is operating, and let it run briefly after switching the unit off so the remaining waste can move through the drain.
Avoid putting items into the disposal unless the manufacturer says they’re suitable. Fibrous scraps, large bones, grease, and starchy or expandable foods can contribute to clogs or jams, depending on the unit and the amount. The owner’s manual is the best guide for your model. If the disposal trips even when you use it carefully and there’s no visible jam, have it inspected rather than repeatedly resetting it.

Frequently Asked Questions
Do all garbage disposals have a reset button?
No. Many models have a manual reset button, often on the underside, but designs vary. Check your owner’s manual if you can’t find one. Don’t try to open the disposal housing to look for it.
How long should I wait before pressing the reset button?
Wait at least 10 minutes so the motor can cool. If the button won’t stay in, give it more time. If it still won’t reset or the disposal trips again, there may be a jam or another fault.
Can I use the disposal if the reset button keeps tripping?
No. Repeated trips mean the overload protector is responding to a problem. Turn the unit off, check for a jam using the manufacturer’s safe method, and stop using it if the problem continues.
Is the reset button the same as the circuit breaker?
No. The reset button is part of the disposal’s overload protection. The circuit breaker protects the electrical circuit in your home. Either one can cut power, but they respond to different conditions.
Conclusion
A garbage disposal reset button restores power after the unit’s overload protector shuts it off, usually because the motor has overheated or encountered a jam. Let the motor cool, switch off power before checking for debris, and press the button only after you’ve addressed the likely cause. If the disposal keeps tripping, hums without grinding, or shows signs of electrical trouble, stop using it and get professional help.
