Add wind bae /
protection from wind.
Fix incoming power supply
Replace the fan motor
Replace the
fan motor.
Replace the
main board.
Start
Check the incoming voltage.
Is it 208/230VAC (+/- 10%) between L1/L2?
104/115VAC (+/- 10%) from L1 to GROUND and L2 to GROUND?
With the power o, turn the fan by hand.
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
No
No
Replace the
main board.
Replace the
main board.
Replace the
main board.
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
during windy situations a wind bae
may need to be added.
Not Windy Windy
Yes
