Start
Check the incoming voltage.
Is it 208/230VAC (+/- 10%) between L1/L2?
104/115VAC (+/- 10%) from L1 to GROUND and L2 to GROUND?
Does it move / rotate smoothly?
Re-apply power. Does the
fan come on and spin?
Measure DC voltage at fan motor plug
CN21 between the Pin 6 (BLUE) and Pin 3
(BLACK) wire while spinning the fan motor.
Does it generate 2~9VDC?
No

Measure DC voltage at fan motor plug CN21
between Pin 1 (RED) and Pin 3 (BLACK).
Does it measure 300~380VDC (+/-10%)?
Measure DC voltage at fan motor plug CN21
between Pin 4 (WHITE) and Pin 3 (BLACK).
Does it measure between 13.5-16.5VDC?
Measure DC voltage at fan motor plug CN21
between Pin 5 (YELLOW) and Pin 3 (BLACK).
Does it measure between 2-6VDC?
Before going to the next step, is the
unit in an area susceptible to high
winds? High winds blowing into the
fan may cause added resistance
and subsequently lower fan speeds
enough to cause the unit to fault. If
this is the case the unit only faults
may need to be added.
