Saunier Duval Thema Condens F 30 E Boiler PCB – Refurbished | Part No. 0020018478

Fault codes, boiler lockout, or total loss of heating and hot water on a Saunier Duval Thema Condens boiler are reliable indicators of PCB failure. The control board manages all critical functions — ignition sequencing, gas valve modulation, pump control, and safety shutdowns. Once it deteriorates, the boiler cannot function safely or consistently. The Saunier Duval Thema Condens F 30 E Boiler PCB (Part No. 0020018478) is the correct OEM-compatible replacement for the Thema Condens F 18/24/30 E, SB variants, and the Themaplus Condens F 30 E, restoring full electronic control and resolving persistent fault codes.

This is a professionally refurbished genuine Saunier Duval component. Each board is inspected, function-tested, and calibrated to original manufacturer specifications before dispatch. The higher refurbished price for this board reflects the complexity of the Thema Condens control architecture — still significantly cheaper than a new OEM board.
