Blower Control

IHKR2 BLOWER CONTROL







- The IHKR2 blower motor is hard-wired to ground The power circuit is used to control blower speed.
- The blower switch supplies voltage to the blower resistor assembly, which contains three low-resistance resistors. Blower switch position determines how many resistors are bypassed and, therefore, how much voltage is applied to the blower motor.
