  1. Well, rollout switches, limit switch, and pressure switch all check out, doing what they’re supposed to (rollout switches are closed, limit switch is closed, pressure switch closes after inducer motor runs). I’ve replaced ignitor/sensor assembly. Thermostat calls for heat, inducer motor runs, but ignitor doesn’t heat, and so gas does not flow. What next ?

    1. Hi Mark! I would like to suggest that you test and see if 110 volts are going to the ignitor when the ignitor is supposed to be glowing. Try to test with the ignitor hooked up to the control board. If you are not getting voltage to the ignitor then more than likely you have a bad control board since you tested all the safety controls and they are closed. If you would like for me to look up parts then please send me your furnace’s make and model number and I will try to help you out. Please send it to arnoldservice@gmail.com our email address. I hope you can find and fix the problem soon! Steve

      1. Thanks, Steve. I’ll look into the voltage going to the ignitor.

        Mark
