Checks
a- Check gas supply pres-
sure;
b- Check ignition spark;
c- Correct amount of air;
d-Check for120VAC at the gas
valve.
a- Check the integrity of the
wire connections between
gas valve and control board.
Press RESET button to
display the Blocking error
description
a- Check for 120 Vac power
connection of the fan.
b- Check PWM connection of
the fan.
Solutions
Replace the power control
board
a- If the gas supply pres-
sure 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 elimi-
nate any obstructions;
d- If the voltage to the gas
valve is not 120Vac the pow-
er control board must be
replaced.
a- If wires are damaged,
replace them
b- If wires are ok, replace
the gas
valve or the power control
board.
Replace the power control
board
Remove the cause of the
Blocking
error
a- If no 120 VAC voltage is
present, replace the power
control board;
b- If no PWM signal is pres-
ent, replace power control
board;
c- Replace the fan.
