first posting for me! Anynway, I bought a home with an inground pool, including an old teledyne laars lite pool heater. The heater has always been touchy, and I only run it when I am at home.
Sometime it will run fine for a few hours before I turn it off, and other times it will run for about 1-2 minutes then start clicking. It sounds like a switch is opening and closing rapidly, thought the unit is still lit and heating. I turn it off right away when I notice that happening.
I know that the pressure switch is touchy, so I bypassed that. But I still have the problem where some switch or valve clicks off and on at times.
Any idea what it could be? The contacts are a little corroded, could it be one of the limit switches is acting up?
