dedicated circuit. If necessary, contact an
electrician to bring the
circuit into specification.
Breaker is open. Close the breaker.
No GFCI circuit. If necessary, contact an
electrician to bring the
circuit into specification.
Check the voltage at the
wiring box:
▪
L1 to ground = 115
VAC
▪ N to ground = 0 VAC
▪
L1 to N = 115 VAC
Refer to " Test the Line
Voltage at the Wiring Box
on page 17."
Check the voltage at the
three-pin connector in
the wiring box:
▪
Pin 1 to pin 2 = 115
VAC
▪
Pin 2 to pin 3 = 0
VAC
▪
Pin 1 to pin 3 = 115
VAC
Refer to "
Test the Line
Voltage at the Wiring Box
on page 17." If
necessary, replace or
repair the electrical
connector or wires.
Check the voltage at the
power board: Pin 1 to
pin 2 = 115 VAC Refer to "
Test Line
Voltage at the Power
Board 7-Pin Connector
on page 17." If
necessary, replace or
repair the connector
from the electrical box to
the power board.
With the blower and
lights energized:
▪
Check 115 VAC L to
N on the connector
(orange) to the
transformer.
▪
On the power
board's ribbon cable
If the ribbon cable is
seated correctly at all
points and there is no
voltage from the power
board, then the power
board or touch control is
bad. Try replacing the
power board first.
