Update- So I had high limit jumped out thought that was it as it was heating.. Wrong upon removing the old sensor they had a thermistor in place of a high limit sensor. So once I put in the correct sensor now the heater fires up and cycles on and off , on and off..I'm thinking internal bypass is...

High Limt Switch was the culprit even though it was flashing the Afs led on the board air switch was closing but the high limit wasn't completing the circuit . I did replace the thermal regulator in the process because it was looking pretty bad thought that might have been a issue. Thanks to all...

Thank you! I'll check that in the am. I thinking it's possibly something odd like that since I've checked and changed out pretty much everything else . Figured someone has experienced something similar. I'll post my findings either way for future reference.

Yes, I've double checked the diagram , spoke with pentair this am said it's probably a air flow issue and maybe I got a bad board off the shelf yesterday. I've had to replace thermistors on mine and others maybe it's something in the water here .. I was just throwing to out there hoping it was...

Could the Fenwal unit be causing any of this I don't think so but trying to rule out any variables

Got a new board from supply house today , hooked it up and it flashes on 128 and revision 13 then goes blank...checked transformer power wires etc.. Nothing got 240 steady power coming in . Is it possible to get a bad board out of the box. It would let me adjust spa and pool set point so its...

I've got a sta rite 400 heater never quite been right since we got the house. I've replaced the thermistor 2 times over the last 4 years but this year the led for the gas sensor was illuminated so I replaced that. Funny thing is while I'm changing that I notice the marking for all the wires to...
