      If the Univex Commercial Food Equipment power unit isn't operating, there are several potential causes. It could be due to burned switch contacts, in which case you should replace the switch. Another cause might be an electrical service interruption, so check the electrical service and replace the fuse or reset the circuit breaker if needed. Finally, a burned-out motor could be the culprit, requiring you to remove and replace the motor.
