This device enables the supply voltage to reach the blower (squirrel cage fan) motor. The blower motor contactor is controlled by the Phase 5 microprocessor controller (computer). (Refer to Section b-1 on page 86 for microprocessor [computer] information.) When 24 VAC is applied to coil A1-A2, the contactor closes and enables the circuit. The blower (squirrel cage fan) motor used for gas model dryers is 15 HP (horsepower) and for steam model dryers is 25 HP (horsepower). The motor wiring configu
