2. With the indoor unit cover removed, remove the two
screws on the left plastic evaporator coil bracket.
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.
3. Check for voltage between Pins 3 and 6. If no DC voltage is
present, the board is bad. If voltage is present, change the
motor.
3.
Remove the cover from the electrical box on the right side
of the indoor unit.

Remove the two screws that hold the electrical box in
place.
