Brahma Burner control unit SM152N.2 24283961

The Brahma SM152N.2 burner control unit (SKU 24283961) is a microprocessor-based controller for atmospheric gas burners, managing the full combustion cycle from pre-purge to flame monitoring and shutdown. It features an integrated ignition transformer and ionization flame detection, with a safety response time of less than 1 second on flame loss. This model operates in intermittent mode and supports single-stage or two-stage burners, with or without forced air. It is a direct replacement for the superseded SM152.2 model.

When selecting a replacement control of this type, verify the exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method. The control must match the burner's configuration and safety requirements; mismatched safety times create a hazard. Ensure the part number aligns with the original unit before ordering.

Typical failures include lockout due to flame loss, ionization circuit break, or short circuit, requiring manual reset via the housing button. Equipment may fail to ignite or shut down unexpectedly. Check the ionization electrode, wiring, and reset function.
