Page 17: Evaporator Fan
Evaporator Fan Evaporator Fan Adjustment Airflow The position of the fan blade in relation to the shroud is critical. Refer to evaporator fan adjustment graphic for specifications. If the fan shorts, it may damage the main control board. If the resistor on the main control board is burnt, you must replace the fan and the board (see 5/16 photo). - Page 18 speed and medium-speed operation. When operating in low and medium speeds, voltage is sent in pulses (much like a duty cycle) as opposed to an uninterrupted flow. This pulsing of 12.6 VDC produces effective voltage being received at the motor, which is the equivalent to a reduction in voltage. Fan speed will be selected and maintained by the control board regulating the length and frequency of the 12.6 VDC pulse.
- Page 19 White Wire (DC Common) The white wire is the DC common wire used for testing. During repairs, DC polarity must be observed. Reversing the DC polarity will cause a shorted motor and/or board. Red Wire (Supply) Each motor uses an internal electronic controller to operate the motor.
