A customer who owns a truck stop calls. There is no cooling in the main dining room. The customer does some of the maintenance, so the technician can expect some problem related to this maintenance program. The technician arrives and can hear the condensing unit on the roof running; it shuts off about the time the technician gets out of the truck. The customer had just serviced the system by changing the filters, oiling the motors, and checking the belts. Since then, the fan motor has been shutting off. It can be reset by pressing the reset button at the fan contactor, but it will not run long. Once arriving on the job on time and making sure the service van is not blocking any restaurant customer parking, the service technician makes sure his face, hair, and uniform are looking neat. He now enters the restaurant, explains to a waitress why he is there, and asks to talk to the owner. Once out of the way of the restaurant customers, the technician politely introduces himself to the owner while handing him a business card, always making eye contact. The fan is not running, and the condensing unit is shut down from low pressure. The technician fastens the clamp-on ammeter on one of the motor leads and restarts the motor. The motor is pulling too much current on all three phases, and the motor seems to be making too much noise. What is the problem and the recommended solution
