Hello. All the wiring looks intact to the board. I am not savvy enough to measure continuity though. There is water in the manifold. The resistance across the SFS is 4.0 ohm. The only thing that has changed is that there is now a symbol on the left side of the display which I presume...

Yes. I see that post now. Thanks! I will check the wires from the sensor to the board tonight. I appreciate the help and will follow up shortly. :)

The water temp is about 73. I will check the manifold for water and also re-check the stack flue temp and reply back. Thank you!
