Brahma Control box TGRD71 18047051

The Brahma TGRD71 control box (SKU 18047051) is a microprocessor-based combustion manager from the Kompact series, designed for automatic ignition, flame monitoring, and safety control of atmospheric gas and liquid fuel burners in intermittent operation. It integrates an electronic ignition transformer and offers programmable pre-purge time of 20 seconds and safety time of 5 seconds. Flame detection is via ionization electrode or photodiode. It fits Brahma burner models BV 77, BV 69, RV 55, EC 22, EC 32, GE 36, and GE 46.

When selecting a replacement control box of this type, ensure the series and type designation, supply voltage, programmed safety and pre-purge times, and flame detection method match the existing unit. The physical base or plug pattern must also correspond to the wiring. Control boxes from different series are generally not interchangeable, and incorrect timing creates a safety hazard. Cross-check the part number and brand against the existing unit before ordering.

Typical failures include lockout due to flame absence or ignition failure, requiring manual reset. The equipment may fail to start or shut down during operation. Check the flame signal, ignition transformer, and external safety devices such as air and gas pressure switches.
