Where Is the Reset Button on a Garbage Disposal? (How to Use It Safely)

Quick Answer: The reset button on most garbage disposals is a small red or black button on the unit’s underside, near the bottom. It’s usually on the flat side facing the floor, just under the sink basin.

Tip: If your disposal suddenly stops working and won’t turn on, press this button once after turning the power off — it may be all you need.

What Does the Garbage Disposal Reset Button Do?

The reset button is designed to protect your disposal from overload or overheating. If the motor draws too much power or gets jammed, the internal breaker trips — and the reset button pops out.

When that happens:

• The disposal shuts off automatically
• You must press the button to restore power
• The reset won’t work until the unit has cooled down (wait 2–5 minutes)

When Should You Reset a Garbage Disposal?

Here are common times you may need to use the reset button:

1. The Garbage Disposal Won’t Turn On

Often caused by a power overload, a tripped breaker, or a loose connection.

2. The Motor Hums But Doesn’t Grind

The flywheel could be jammed — you’ll hear humming but no action.

3. The Disposal Is Clogged

Clogs can be triggered by:

• Bones
• Coffee grounds
• Fibrous peels (potato, celery)
• Grease and oils

How To Reset Your Garbage Disposal

1. Turn off the power at the switch or unplug the disposal.
2. Always cut power before touching anything.
3. Look for the red or black reset button underneath the unit.
4. It’s usually about the size of a pencil eraser.
5. Press the button firmly.
6. If it stays in, the unit is reset. If it pops back out immediately, let it cool down longer.
7. Plug back in / turn power on and test the switch.

What If the Reset Button Doesn’t Work?

Sometimes, the reset button won’t respond due to a deep clog or jam. You can manually unjam it using the steps below.

Tools You’ll Need:

• Allen wrench (usually included with disposal)
• Flashlight
• Pliers

Step-by-Step:

1. Shut off power completely.
2. Use the flashlight to inspect the opening for visible clogs.
3. Insert the Allen wrench into the hex hole on the bottom of the unit.
4. Rotate it back and forth to free up the flywheel.
5. Remove debris using pliers.
6. Press the reset button again, then restore power and test.

If it still doesn’t work, it may be time to replace the unit or call a plumber.
