Step 5 · Press the Reset Button

After the jam is cleared, you need to reset the disposal's internal motor protection. The humming sound from the jammed motor likely caused it to overheat and trip the overload protector. Look on the bottom of the disposal unit for a small, typically red or black, button. If the button is popped out, press it firmly until it clicks and stays recessed. If it's already recessed, the unit may not have tripped, or it may have reset itself as it cooled.
