Brahma Combustion control unit SE191.3 24653001

The Brahma SE191.3 combustion control unit (SKU 24653001) is a microprocessor-based control box for gas burners. It manages automatic ignition, flame monitoring, and safe operation, supporting single-stage or two-stage atmospheric gas burners in intermittent mode. The unit features built-in ignition transformer, ionization flame detection, two independent safety contacts, and an auxiliary contact for ignition. It requires manual reset after a safety lockout.

Parts of this type are selected by exact series and type designation, supply voltage, safety and pre-purge times, flame detection method (ionisation, uv, or ir), and base or plug pattern. Confirm that the series designation, voltage, timing, and detection method match the original unit exactly before ordering. A control box from one series is normally not interchangeable with another, even within the same brand.

When items of this kind fail, the burner may fail to start, lock out without ignition, or shut down during operation due to loss of flame signal. Common causes include faulty flame detection (electrode or wiring), failed internal components, or incorrect safety timing. Check the flame detector, wiring, and supply voltage, and verify that the control box settings match the burner configuration.
