Outdoor Fan Motor; Slide-Out Chassis - GE AZ85E09DAC Technical Service Manual

Outdoor Fan Motor

The outdoor fan motor is a permanently lubricated,
variable speed DC motor, using an internal speed
control in the motor.
The indoor fan and outdoor fan will operate si-
multaneously under normal operating conditions.
However, if the heat pump is operated when high
outdoor temperatures are present, the indoor coil
may overheat. Should the indoor coil temperature
reach 131°F, the main board will shut the outdoor
fan off. A 5°F hysteresis loop will restore outdoor fan
operation when the indoor coil temperature lowers
to 126°F.
To energize the fans, press the FAN button on the
thermostat. When fan ON mode is selected, the fans
will run continuously, independent of the compres-
sor or heaters. Selecting AUTO on the thermostat
will cause the fans to automatically cycle on and off
with the compressor or heaters. The fans will always
run when the compressor or heaters are operat-
ing. They will start before compressor or heater
operation, and will stop after compressor or heater
operation has ended. The fans can also be set to
run continually, regardless of thermostat setting, by
placing the CONST FAN dip switch in the UP position
