Hi! New user here. I just joined but have been reading posts for about a month. Here's why...
I really need some help.
I have a Sta-Rite SR400LP Heater. Its about 16 months old. Worked fine all last season. Started up fine this season and stopped working in early July.
When I press "Pool on" and set the desired temp to a number higher than the current water temp the blower turns on and the "Service Heater" LED comes on. When I look at the underside of the control board I see the "AFS" LED on. When I look at the FENWAL I see the AFS LED flash at 3 second intervals.
I checked every wire and opening for rodent damage etc and found nothing. I replaced the control board, the AFS Switch and even the FENWAL. Still getting the same error indicators.
Any thoughts?
