Without doing more troubleshooting i would have to say that it is the main board (the board with the knobs on it) Take it out and see if there is any corrosion on it.

Teledyne laars ES125 repair manual


The exchanger alone will run $600 or more, and the headers aren't cheap either. Best to replace the heater. I have had customers do expensive repairs (despite my objections) only to have other expensive parts (T-stats, gas valve, burner tray..) break soon afterward.

Jandy is the closest relative of Teledyne, they used to be affiliated. RayPak has been making reliable heaters for decades.
