b- Check spark and ignitor
rod.
c- Correct amount of air;
d-Check for 120VAC at the gas
valve.
e- Ensure that the gas valve
is functioning properly by
checking for changes in gas
pressure.
a- If the gas supply pressure
is incorrect, it must be
adjusted to the correct
pressure;
b- If spark is not present
check for correct ignition
electrode position;
c- If the combustion air
pressure is incorrect,
inspect the vent system and
eliminate any obstructions;
d- If the voltage to the
gas valve is not 120Vac the
power control board must
be replaced.
2 GV_RELAY_ERROR Failure detected in the GV
(Gas Valve) relay
a- Check the integrity of the
wire connections between
gas valve and control board.
a- If wires are damaged,

Therefore it causes a Locking
error.
a- Press RESET button to
display the Blocking error
description
b- Check error log on
touchscreen.
c- The blocking error that
occurred previous to current
locking error will be the
cause (i.e.- 163 LowExFlow).
Remove the cause of the
Blocking
error
5 FAN_ERROR_NOT_RUNNING Fan is not running for more
than 60 seconds.
a- Check for 120 VAC power
connection of the fan.
b- Check PWM connection of
the fan.
a- If no 120 VAC voltage is
present, replace the power
control board;
b- If no PWM signal is
present, replace power
control board;
c- Replace the fan.
6 FAN_ERROR_TOO_SLOW Fan runs too slow for more
than 60 seconds
7 FAN_ERROR_TOO_FAST Fan runs too fast for more
than 60 seconds
8 RAM_ERROR Internal software error Replace the power control
board
9 WRONG_EEPROM_SIGNATURE Contents of E2PROM is not up
to date
Replace the power control
board
10 E2PROM_ERROR Wrong safety parameters in
E2PROM
Replace the power control
board
11 STATE_ERROR Internal software error Replace the power control
board
