I have been whipping my old pool back into shape but so far the heater has stumped me. It is an old heater Raypak Gemini Natural Gas 309k btu circa 1980ish. The pool is from 1969 and was re-plastered in 2006. The heater allegedly worked when we bought the house in dec 09, it was left on by the house inspector and ran for a week until the previous owner noticed it was on (the pool was 85 degrees in winter lol). The home warrenty company got in a dispute with us over the pump and we dropped the policy before realizing the heater was also dead.
After we moved in I tried to fire the heater up to no avail, I had the gas co come out and light the pilot and check it for leaks, the pilot would light but that was all that would happen. When I turn the temp dial to any temp there would be no fireworks or roar of the burner firing up, I left it on with the temp knob to "spa" (the hottest setting) for hours but no dice.
Any thoughts on what needs to be replaced/serviced or on the likelihood this being a lemon/money pit to try to service? The thermocouple is over $100 and various other parts put the servicing into the $400ish range on the low end I'm guessing
I am debating cutting the old copper pipes out and bypassing the heater completely if it is a lost cause (probably scrap it)
