• If 24 VAC is present at the main control board, check

 

 

 

the wiring between the main control board and the gas

 

 

 

valve. Replace the wiring if necessary. Do not

 

 

 

disconnect the wiring from the gas valve and attempt

 

 

 

to measure voltage at that point. The main control

 

 

 

board can detect if the gas valve is not connected and

 

 

 

will display the Gas Valve / Connection fault.
