Before working on your garbage disposal, make sure any power to it is turned off. First, check to see if the disposal is plugged in correctly. Attempt a reset by locating and pressing the red reset button located on your unit. Check your service panel to see if the circuit is tripped. If so, reset the breaker related to your disposal. Inspect your unit for signs of loose wires. If none of these seem to solve the problem, call us. We can assist you with repair or replacement.
