I have a SR400na it has a code of SFS and pool heater will not fire up at all and the service heater indicator light comes on immediately after I reset and clear the code
I change the stack temperature thermal well to see if that was the problem but it did not clear the problem of the SFS code.
I check continuity on the stack thermal well wiring to the electronic card plug continuity was good
I put a jumper on the stack thermal well wires and I can get the heater to fire up and run like normal.
I Spoke with the manufacturer and they said that it could possibly be the electronic card.
Has anyone ever had this problem?
