How to Unjam a Stuck Garbage Disposal in Under 10 Minutes

The Frustrating Hum of a Jammed Disposal

You flip the switch to clear the kitchen sink, but instead of the familiar roar, you hear a low, ominous hum. Your garbage disposal is jammed. When something hard gets wedged between the rotating impeller blades and the shredder ring, the motor locks up to prevent burning itself out. Don't panic, and definitely don't call an expensive plumber just yet. You can easily fix this common household issue in under 10 minutes with just one simple tool.

Tools and Materials Needed

• A 1/4-inch Allen wrench (hex key): Most disposal units come with one, or you can find it in a standard hex key set.
• A flashlight: To help you see under the dark sink cabinet.
• A wooden broom handle or wooden spoon: Used as an alternative method if you do not have an Allen wrench.

Step 1: Cut the Power (Safety First!)

Before you touch anything, you must ensure there is absolutely no electricity running to the unit. Never put your hands inside the garbage disposal. Locate the power cord under the sink and unplug it from the wall outlet. If your disposal is hardwired directly into the wall, go to your home's main electrical panel and switch off the circuit breaker labeled for the garbage disposal or kitchen outlets.

Step 2: Locate the Hex Socket

Grab your flashlight and head underneath the kitchen sink. Look at the very bottom of the garbage disposal cylinder. Directly in the center of the bottom plate, you will find a small, recessed hexagonal hole. This hex socket is connected directly to the motor's internal flywheel shaft, allowing you to manually rotate the blades from the outside.

Step 3: Manually Free the Jam

Insert the 1/4-inch Allen wrench into the hex socket. Firmly grip the wrench and begin turning it back and forth. It might feel incredibly stiff at first. Apply steady, firm pressure. Turn it clockwise, then counterclockwise. Continue doing this until the wrench spins freely in a full 360-degree circle. When the wrench moves easily, the obstruction has been dislodged from the blades.

Step 4: The Wooden Spoon Backup Method

If your disposal doesn't have a bottom hex socket, or if you can't find an Allen wrench, you can tackle the jam from above. With the power still completely disconnected, insert the wooden handle of a broom or a sturdy wooden spoon down through the sink drain. Wedge the end of the handle against one of the metal impeller blades. Forcefully push the handle to rotate the impeller plate back and forth until it spins freely.

Step 5: Reset the Thermal Overload Switch

When a disposal jams, its built-in thermal breaker trips to prevent the motor from overheating. Look back at the bottom of the disposal unit under the sink. Look for a small, square, red button. If the button is popped out, press it firmly back in. If it doesn't click, wait about two minutes for the motor to cool down, then try pressing it again.

Step 6: Flush and Test

Clean any loose debris out of the sink basin. Plug the disposal back into the outlet (or turn the circuit breaker back on). Turn on the cold water faucet and let it run at a high flow rate. Finally, flip the disposal power switch. It should run smoothly and quietly. Let the water run for another 30 seconds to flush away the pulverized debris that caused the jam.
