Indoor Fan and Capacitor
The indoor fan is a 265/230/208 VAC, permanently lubricated motor. Indoor fan speed is selected in the
following manner:
When the green thermostat wire is connected to the high-speed fan (GH) terminal:
DUCT SWITCH UP = HIGH FAN SPEED
DUCT SWITCH DOWN = MEDIUM FAN SPEED
When the green thermostat wire is connected to the low-speed fan (GL) terminal:
DUCT SWITCH UP = MEDIUM FAN SPEED
DUCT SWITCH DOWN = LOW FAN SPEED
The indoor fan and outdoor fan will operate simultaneously under normal operating conditions. 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 compressor 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 operating. 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 (see Dip Switches section of the Features and Operation chapter).
The indoor fan capacitor is located under the electronics cover and below the driver board.
To remove the outdoor fan:
1. Remove the unit from the cabinet (see Slide-
Out Chassis chapter).
2. Remove the left and right divider assemblies.
3. Remove the electronics cover (see Main Board
chapter).
4. Remove the resistance heaters (see
Resistance Heaters chapter).
5. Remove 1 screw and slide the metal panel
from in back of the indoor coil out the right side
of the unit.
6. Loosen the Phillips head setscrew securing
the blower wheel.
Note: Position blower wheel setscrew on the flat
side of the motor shaft when reassembling.
