Troubleshooting Error Codes
Gas Valve Checking Procedure
•
Cycle power and/or clear any alarms on the display.
•
Locate the large black wiring harness plugged into the top of the gas valve.
Loosen the Phillips head screw at the top of the connector, then disconnect it
from the gas valve.
•
With connector removed, cycle the power on, while display is showing
“IGNITION” check voltage across pins 1 & 5 in the connector. Voltage
reading should be between 10-15VAC. If the voltage reading is correct then
the gas valve is being supplied power and should be operating. If you do not
get 10-15VAC then we could have a faulty gas valve harness or faulty
control board.
Gas Valve Harness and Control Board Checks
•
Trace the wire harness from the gas valve backwards to P4 connector on the
ignition control board and Disconnect the Molex connector from the P4
connection.
•
Cycle power and/or clear any alarms. When the display is showing
“IGNITION”, measure for 24 across the outside pins on the P4 connector.
•
If you get the 24V, then the control board is operating correctly. Replace the
gas valve wiring harness.
•
If you do not get the 24V, replace the ignition control board.
•
Is the gas valve working?
The best way to confirm the gas valve is operating is with a manometer. Reconnect all
wiring, and connect a manometer to the inlet port of the gas valve. Cycle power and check for a pressure drop
when the unit goes to “IGNITION”. If you have ANY drop at all, the gas valve is opening and allowing gas
flow. (See page 47 for instructions)
•
If you do not have a manometer available, a less accurate check can be done. With all wiring reconnected, cycle
power on and hold your hand on top of the gas valve solenoid, when the unit goes to “IGNITION” you should
feel a noticeable click.
•
If you do not get any pressure drop with a manometer and/or do not feel the solenoid click, replace the gas
valve.
