I have a g21 that will fire and run for about 30 seconds then shut off and the blower will kick on for about 30 seconds then repeats the process. Unable to acheave thermostat setting. The green light on the igniter controller stays solid green the whole time. I had the flame rod changed 6 years ago for similar issues could it be bad already?

    All the guys who knew how to work on Pulse furnaces are retired. It might be time to replace.

    Surprising that your Pulse hasn't retired in previous century. I wonder if any pulse boiler somewhere, Hydrotherm or Fulton, is still blasting away?
