A disposal was not functioning properly, as the motor was unresponsive. I began by disconnecting the power supply to ensure safety. Next, I removed the disposal unit from the sink and inspected the motor for any visible damage or obstructions. Upon discovering that the motor was indeed faulty, I ordered a replacement disposal unit. After installing the new unit, I reconnected the power and tested the disposal to confirm it was working correctly. The customer was pleased with the restored functionality of their kitchen appliance.
