Question about Hayward H Series Pool & Spa Heater 400k Btu Propane Gas Milivolt Ignition H400p1
I changed my igniter but did not help. I still end up getting an IF falure. Strangely, after the unit has been rained on for a long time the heater will stay on much longer then turns off after 10 or 15 min. Hayward thinks its an electrical problem. any suggestions or ideas or any voltage measurements I can check to narrow the problem down would be appreciated.
Flame rectification is made by a ground signal in the heater. Wet heater = better grounding = longer running time. Look for rusty areas in and around the ignitor area and wire brush them off so the signal that the ignitor has a pilot flame on can get to the board. The only other problem could be the control module itself not recognizing the rectification signal which would mean a new module.
