Hola All,
Going through the checklist to open my pool recently and finally got to the last item, the heater, which never goes well and this year is no different !
Heater powers on, flashes the LED to indicate heating and then does nothing else! I have the service flowchart and worked through most of it yesterday until I hit a wall.
When I got to the section about the fan not coming on (top of page 2) it says to remove the connector from pins F1 and F2 on the Fenwal Ignition Control Module and check these pins for continuity. So I did, and it's open, guide says replace ICM (~$300)
The flowchart seems to cover the Temp Control Panel and various safety switches fairly well but seems to gloss over the ICM and only mentions the Air Flow Sensor in the sidebar.
In my search to troubleshoot the ICM I came across several suggestions to jumper the fan on through the black and brown wires (mine are black and blue) that connect to pins F1/F2 of the ICM (which I assume is a relay?) Did that and ICM now powers up and I get an air flow error on the ICM (1 flash on LED).
So, this is where I'm stuck. I've seen it suggested to jump the air flow sensor out of the circuit but can't see how to do this?
Would really like to be sure everything else works before shelling out money on parts as I've had trouble in the past with what seems to be almost everything with this unit from the start.
Any help on what to do? where to go next? (that excludes, as my wife suggests, buying a new heater I looked at the Raypak and they look nice, but OUCH!!! on the $$$$)
