Make sure it’s getting power

If your garbage disposal isn’t doing anything at all, it might not be getting power. Here’s how to check:

Check the outlet and power cord

1. 1. Ensure the disposal is plugged in. Sometimes the cord can become loose or unplugged accidentally.

1. 1. Look under the sink and verify the plug is firmly connected to the outlet.

1. 1. Test the outlet by plugging in another device, such as a lamp or phone charger.

1. 1. If it’s a GFCI outlet and not working, try resetting it by pressing the “reset” button on the outlet.

Examine the circuit breaker

1. 1. If the outlet isn’t the issue, check your home’s electrical panel.

1. 1. Look for a tripped breaker associated with the garbage disposal. A tripped breaker might be in the “off” position or not fully on.

1. 1. Flip the breaker off and then back on to reset it.

1. 1. Return to the disposal and test it again.

Reset the garbage disposal after it overloads

Garbage disposals have a built-in overload protector to prevent damage when they’re overloaded with too much food waste. Resetting the unit often resolves the issue.

Press the reset button

1. 1. Turn off the disposal switch.

1. 1. Clear out any visible food scraps or debris from the disposal.

1. 1. Find the reset button, usually a small red or black button on the bottom or side of the unit.

1. 1. If the button is popped out, press it firmly until it clicks.

1. 1. Turn on the cold water and test the disposal again.

Check if it’s jammed

If the disposal hums but doesn’t grind, there’s probably something stuck inside.

Remove obstructions

1. 1. Turn off the disposal and unplug it or shut off the breaker. Safety first!

1. 1. Shine a flashlight into the disposal and look for objects like utensils or large food scraps.

1. 1. Use tongs or pliers to carefully remove anything stuck. Never put your hand in the disposal.

1. 1. Test the disposal again after clearing it out.

Manually move the flywheel

1. 1. Look under the disposal for a hex-shaped hole in the center.

1. 1. Insert an Allen wrench into the hole and twist it back and forth to manually move the flywheel.

1. 1. You might feel the jam loosen as you turn the wrench. Once it moves freely, remove the wrench, press the reset button, and test the disposal again.

Look for clogs

If water isn’t draining properly, there might be a clog in the disposal or drain.

Try to clear the clog

1. 1. Fill the sink with a few inches of water.

1. 1. Use a cup plunger (not a toilet plunger) over the disposal drain.

1. 1. Give it several strong plunges and see if the water starts to drain.

1. 1. If it’s still backed up, try using a sink auger to reach deeper clogs.

Test the disposal switch

Sometimes the issue is with the switch that controls the disposal.

Check the switch

1. 1. If flipping the switch doesn’t do anything, it might be faulty.

1. 1. Turn off the circuit breaker for safety.

1. 1. Remove the cover plate on the switch and check that the wires are securely connected.

1. 1. If you have a multimeter, you can test the switch for continuity.

1. 1. If the switch isn’t working, it’ll need to be replaced.

Consider the motor

If you’ve tried everything else, the motor might be the problem.

Signs the motor is bad

• • The disposal doesn’t make any noise when you flip the switch.

• • You notice a burning smell coming from the unit.

• • Pressing the reset button doesn’t restore power.

If the motor is burned out, you might be able to replace it, but in many cases, replacing the whole disposal is a better option, especially if it’s an older model.
