Brahma Electronic control board (PCB) 350.4D005 16020560

The Brahma Electronic control board (PCB) 350.4D005 (SKU 16020560) is a control box for burners, designed to fit the Mora ST15163 (15163) boiler. It manages the ignition sequence, enforces safety times (pre-purge, ignition, flame proving, lockout on failure), reads pressure switches and flame signals, and drives the ignition transformer, gas valve, and fan. This board is specific to the boiler model and is not interchangeable across series.

Parts of this type are selected by confirming the exact series and type designation, supply voltage, safety and pre-purge times, flame detection method (ionisation, UV, or IR), and base or plug pattern. The board must match the boiler model; no generic substitute is permissible. Verify compatibility with the appliance model before ordering.

When control boards of this kind fail, the burner may not start, lock out after repeated ignition attempts, or shut down unexpectedly during operation. Symptoms include no spark, no gas valve activation, or fan running without ignition. Check for error codes, loose connections, and damaged components on the board.
