Opened pool today with help of a pool-boy who will likely not be able to come back for many days. Started the heater and all seemed fine --but as I was in the yard tonight I heard it re-fire once. Didn't think much of it. A bit later I was checking to see the temp and noted the "Heating" light was blinking, and then went to solid. So I hung out to monitor it a bit and noted the "Heating" light blink again and then the "Service Heater" light came on. At that point I just turned it off. Not sure if the "Service Heater" light had come on previously and then gone off, or if I was watching as it lit for the first time.
I can call a plumber to look at it, but pool-boy will be unavailable. Anyone with thoughts on what might be the issue? Only thing I can think of is that I recall last year, when same pool-boy installed it, he adjusted an air flow switch. I don't remember if that was something that was winterized, but I know that today he did not take off the side panels at all -- just hooked up the water pipes (I take my pool down for the winter), plugged it on, opened the gas on my line to the heater, and fired it up.
Any help or warnings for what I might be looking at for a fix are welcome. I will keep the unit off, unplug it, and close the gas line to it until someone qualified takes a look, but I'd love any insight as to what the cause may be. This is only its second season so I'm hoping it is not the unit itself, but something pool-boy and I have done wrong in the start up.
