Brahma PCB (control board) APG1.05 16020595

The Brahma APG1.05 control board (SKU 16020595) is an electronic PCB designed to manage gas-fired heating boilers. It initiates the fan and opens the gas valve as part of the ignition sequence. This board is categorized under electronic control boards for burners and boilers.

When selecting a replacement control board of this type, the exact series and type designation must match the original. Verify the supply voltage, safety and pre-purge times, flame detection method, and connection pattern (base or plug). Even within the same brand, boards from different series are not interchangeable; a mismatched safety time is a safety hazard.

Typical failures of such control boards include lockouts when flame is not confirmed within the safety time, or failure to start the fan or open the gas valve. Check for correct voltage supply, proper sensor readings, and secure connections. If the board locks out repeatedly, inspect the flame detection system and wiring.
