Brahma Control box TGRD71 18047053

The Brahma Control box TGRD71 18047053 is a microprocessor-based combustion manager from the Kompact series, designed for automatic ignition, flame monitoring, and safety in atmospheric gas and liquid fuel burners operating intermittently. It features a built-in high-voltage ignition transformer, pre-purge time of 20 seconds, safety time of 5 seconds, and supports both ionization electrode and photodiode flame detectors. The device reacts to flame loss in less than 1 second and enters a non-volatile lockout state requiring manual reset after any fault. It fits Master models BV 77, BV 69, RV 55, EC 22, EC 32, GE 36, and GE 46.

Parts of this type are selected by matching the exact series designation, supply voltage, safety and pre-purge times, and flame detection method (ionization, UV, or IR) used by the burner. The base or plug pattern must also match the wiring harness. Before ordering, verify the model designation and electrical ratings against the original part, and consult the manufacturer's documentation for specific safety time settings. These controls are typically panel-mounted and wired via a standard base in larger burners.

When items of this kind fail, the burner may lock out without restarting, often due to ignition failure, flame loss, or a faulty flame detector. The equipment may show no response to heat demand or repeatedly cycle through lockout. Check the flame detector, wiring connections, and the control's reset button, and verify that the safety and pre-purge times are correctly set.
