I installed the new touch screen honeywell last night and the heat came on in the morning, but house was cold when I got home. I could hear the inducer motor coming on, but no fire. Then I noticed the gas valve was blinking 6 blinks (control in soft lockout). I verified my wiring which I think is pretty straight forward and I didn't see any problems. I shut the furnace off a couple of times and then it fired up and brought the house up to temp. Then it stopped firing again. I even went back to my old thermostat and I can't even get that to work it still won't fire. I took the panel off by the burner and I don't see the igniter glowing. The furnace is a arcoaire 2 stage 2 years old. Any suggestions on how to test the igniter? Thanks for the help I enjoy reading this board.
