Saunier Duval Thema F23 E PCB Ref. 05741000
When you turn on the tap or the heating, the Saunier Duval Thema F23 E PCB controls the ignition, the modulation of the burner, and the boiler pump. If it fails, you will notice that the boiler does not start, gets locked, or behaves erratically. This board is compatible with several models, including the Thema C 23 E, F 23 E, C AS 23 E, and F AS 23 E, as well as those from the Themaplus and Combitek ranges. Replacement requires first confirming the fault of the part through technical diagnosis, even when these symptoms are present and the boiler is not functioning properly.
