Hi all. My 2.5 yr old pool heater (Max-e-Therm 333, natural gas) has stopped working. The Service Heater light is on. I had a technician from a local pool service company come out. They said they checked wires, electrical connections, gas pressure and flow Ė all fine, but still not working. Their next proposed step is to start replacing parts. They want to replace the Ignition Control Module and the Control Board. But they are by no means certain this will fix the problem. They say it may require additional parts.
Does this sound like a reasonable course of repair? Normally I would dig in and do some initial diagnosis/poking around myself, but I have a big backlog of house projects and just need to get this fixed. It seems like there should be a better way to diagnose problems besides just starting to replace parts, but I really donít know anything about pool heaters.
Thanks in advance for any help!
