REMOVAL & INSTALLATION



Front

The blower motor and fan is mounted in the bottom of the heater case. Depending on model and equipment, it may be possible to remove the blower without removing the heater case. If there is insufficient clearance below the case to get the motor and fan free, the case must be removed.
