- Gas valve turned off. - Manual shut-off valve. - Green/Yellow wire MUST be connected to furnace sheet metal. - Flame sensor must not be grounded. To determine whether the problem is in the gas valve, igniter, or flame sensor the system can be operated in the component test mode to check the igniter. First remove the R thermostat connection from the control and initiate the component test sequence. Does the igniter glow orange/white by the end of the 15 second warm-up period?
