Reply #8: Interesting - I had a similar experience with my pool heater mfgr.

My old heater conked out last year, and with the choice of spending $500 to fix it or $1000 to get a new one, I opted for new. My pool guy put it in, but it would stop igniting after awhile. You'd hear the starter click, the gas would woosh so you knew it lit, but then it would stop. My pool guy was befuddled and kept suggesting different stuff to try. Finally I called the manufacturer, spoke with a tech who knew exactly what the problem was, sent me a part, my pool guy replaced it, and it's been fine ever since. Started up like a trooper this year.

Let us know how this goes!
