Brahma Control box VM44G 37200755

The Brahma VM44G control box (SKU 37200755) is a microprocessor-based controller for automatic ignition, flame monitoring, and safe operation of forced draft gas burners. It operates at 220–240 V, with a safety time of 2 seconds and a pre-purge time of 30 seconds. Flame detection is via ionization electrode, and it supports single-stage or two-stage burner operation. The device is certified to EN 298, has an IP40 protection class, weighs 0.4 kg, and is designed for intermittent duty with a service life of 250,000 cycles under maximum load. It features non-volatile lockout with manual reset and includes a compact housing.

When selecting a replacement control box of this type, ensure the supply voltage, safety time, pre-purge time, and flame detection method match the original unit. The mounting pattern and connector base must be compatible with the burner's wiring. Verify the fuel type (gas) and burner configuration (single-stage or two-stage) to ensure proper operation. Always compare the exact model and part number with the original specification before ordering.

Common failures of this kind include lockout due to flame detection issues, such as a faulty ionization electrode or contaminated flame sensor. The burner may fail to start or shut down during operation, often indicated by a lockout light. Check the electrode position, wiring, and the control box's fuse or varistor for damage. If the control box locks out and cannot be reset, it may need replacement.
