JLM Posted October 16, 2014 Report Share Posted October 16, 2014 Jandy Pool Heater LX400N-L Manufactured 2003 will light sometimes and when it does, it will not re-light when the water cools off. I get an AGS error code. Before this happened it was blowing a 2A fuse. The tech said it was time for a new heater. Any suggestions before spending $3000+?

MikeThePoolman Posted October 23, 2014 Report Share Posted October 23, 2014 I love Jandy but that heater has had MANY issues. Cut your losses and buy a new heater. I am very good at heater repair and I've been down this road too many times- repair, another repair, another repair, $900 later and you've got an 11 year old heater that's still temperamental. Go Pentair or Sta-Rite and you'll be fine. Mike Quote Link to comment Share on other sites More sharing options...

stevenz1g Posted December 13, 2014 Report Share Posted December 13, 2014 Although an AGS sensor is a cheap fix, it's weird that the hi-limit isn't also popping, as they're usually within a couple degrees within each other. Simply put, the AGS sensor simply tells the gas valve to shut because water temperature leaving header is too high... which could mean a slew of things (flow, heat exchanger, bad sensor, bad pc board, bypass inside header bad?) If you're mechanically inclined in the least sense, put a multimeter on the sensor and see if it's always bad, opens early, or is in fact opening as it should be. Compare with your hi limit sensor. If you've had a good history with your tech, and judging by these other commentors, it may be time for that new heater. Quote Link to comment Share on other sites More sharing options...
