Once I set the thermostat to the desired temp it begins to activate but will not fully light. I am
clearly getting a good spark and the piolet light is clearly well lit but the main burners never seem to light and the blower to activate. I seem to have good gas flow as when I turn off the gas feed to the unit the piolet light will extinguish and is easily re-lit when I turn the gas feed back on but but the igniter will just keep sparking away forever igniting an already lit piolet until I turn off the thermostat. The constant snapping of the ignitor is all I get.
