I have a Hayward H500FDPASME (500,000 btu propane heater) that I bought and installed in 2017.
It's been working great until yesterday.
Control panel allows me to switch between off, spa and pool; and displays the current water temp and allows me to set a setpoint temp.
I hear a click-click which I've traced to one of the relays on the ignitor board. It click every 30 seconds or so.
That's all the unit does. Does not throw a code. Does not show signs of attempting an ignition (no gas is released, I don't believe an ignition spark is present).
I noticed the transformed is hot, as if there's something drawing current -- perhaps whatever it's actually doing when it goes click (it's actually a single click).
Interestingly, it clicks even in the off mode. As if it's trying to do something in the off mode, and failing.
Fuses are good. No codes displayed. Transformer output (I think) is around 30 volts.
I'm in the mountains, and the evenings get down to about 60, so I need the heater to keep my water at a very comfortable 84*
Any ideas?
Thanks!
Joe
