Brahma Control box SM192N.2 24283301

The Brahma SM192N.2 control box (SKU 24283301) is a microprocessor-based burner management system for automatic ignition control, flame monitoring, and safe operation of two-stage atmospheric gas burners with an intermittent cycle. It is suitable for burners with natural draft or forced air supply. This model supersedes SM191 and enables operation at two power levels (partial and full load) for fuel savings and improved temperature regulation. The pre-purge time is 1.5 seconds. It is designed for gas or oil fuel types.

Parts of this type are selected by matching the exact series and type designation, supply voltage, pre-purge and safety time settings, flame detection method, and base pattern or plug configuration to the existing wiring harness. Burner controls are typically not interchangeable across series, even within the same brand, due to safety time mismatches. Before ordering, verify the model code from the original part label and ensure the wiring diagram and safety parameters align with the equipment.

When items of this kind fail, the burner may fail to start, lock out during operation, or shut down unexpectedly. Common issues include failure to prove flame within the safety time, leading to lockout, or malfunction of the air pressure switch input, preventing fuel valve opening. Check the flame sensor, wiring connections, and supply voltage, and verify that the control's timing parameters match the burner's requirements.
