TROUBLESHOOTING GUIDELINES

PROBLEM
The gas control valve has sensed
inadequate or no earth ground.
The gas control valve has sensed
reversed polarity in the 120 VAC
power supply.
Pressure switch circuit remaining
closed for more than 5 seconds
after heating cycle begins.
Blower may not start in this
condition.
Pressure switch circuit remains
open longer than 5 seconds after
the blower is energized.
Blower may run continuously in
this condition.
The gas control valve has detected
an open igniter circuit.
Ignition/fl ame failure.
The gas control valve has reached
the maximum number or retries (3)
for ignition and is currently locked
out for one hour.
Cycle the power to the water heater
off and on to reset.
1 Ensure the wall outlet (power supply) is properly
grounded.
2 Ensure all ground connections/wires on the water
heater are securely connected.
1 Ensure the wall outlet/power supply is properly wired.
2 Ensure all internal 120 VAC wiring connections and
wiring harness have no reversed wires. 120 VAC "hot"
wire must connect to the on/off switch.
1 Ensure air pressure switch circuit wiring is correct and
the air pressure switch is not jumpered.
2 Replace the air pressure switch.
1 Ensure the air pressure switch sensing tube is properly
connected at both ends and is not kinked or damaged.
2 Ensure the correct size of vent and intake air pipe (direct
vent products) was used per the installation instructions
in the manual that came with the water heater.
3 Ensure maximum number of elbows or maximum
equivalent feet of vent or intake air pipe has not been
exceeded per the installation instructions in the manual
that came with the water heater.
4 Ensure there are no obstructions in the vent or intake
air pipe.
1 Check wiring to the hot surface igniter assembly -
replace igniter assembly if wiring is damaged or worn.
2 Check resistance of the igniter at igniter assembly plug
- should be between 11 and 18 ohms - replace igniter if
open or shorted.
3 Check igniter assembly plug and the socket on the
bottom of the gas control valve for good connection.
4 Replace igniter assembly if the plug is worn or
damaged.
5 Replace the gas control valve if the igniter assembly
socket on the bottom of the control is worn or damaged.
1 Gas supply is turned off - pressure is too low.
2 Ensure the fl ame sensor is clean - use fi ne steel wool
to clean the fl ame sensor.
3 Manifold gas pressure to the burner is too low.
4 Check igniter assembly plug and the socket on the bottom
of the gas control valve for good connection. Replace
igniter assembly if the plug is worn or damaged replace
the gas control valve if socket is worn or damaged.
5 Replace igniter assembly.
