Indoor Fan Motor Test Procedure
If the indoor fan motor does not run:
1. Disconnect power to the system.
2. Remove the return air cover and access the fan motor
circuit board connection.
3. Reset power and turn the remote control fan command to
Fan On mode.
Motor Test:
1. If the motor doesn’t run, check for 310VDC between Pins 1
and 3. If it is not present, the indoor board is bad. If voltage
is present, continue on.
2. Check the voltage between Pins 3 and 4. The voltage
should be +15VDC. If it is not present, the board is bad. If
voltage is present, continue on.

is present, the board is bad. If voltage is present, change
the motor.
