Brahma Control board FC M32C 37428030

This is a control board (SKU 37428030) from Brahma, model FC M32C, intended for condensing gas boilers with premixing. It functions as a burner control box, managing the ignition and safety sequence: it receives the heat demand signal, starts the fan, monitors the air pressure switch, energises the ignition transformer, opens the gas valve, and verifies flame presence within the programmed safety time. If no flame is detected, the board initiates lockout.

For this kind of part, the exact series and type designation must match the original, along with supply voltage, safety and pre-purge times, flame detection method (ionisation, UV, or IR), and the base or plug pattern. Parts of this type are not interchangeable across series within the same brand; using a control with a different safety time is a safety hazard. Before ordering, verify that the replacement matches the original in all these aspects and consult the appliance documentation.
