It processes signals from internal sensors, thermostats, and safety devices, then controls ignition sequences, burner operation, fan control, and system diagnostics. If abnormal conditions are detected, the board initiates protective shutdowns to maintain safe operation. Replacing a faulty BMU PCB helps resolve issues such as ignition failure, intermittent operation, and recurring fault codes.\u003c\/p\u003e\n\u003ch3 data-start=\"838\" data-end=\"857\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"858\" data-end=\"1163\"\u003eThis control board is engineered specifically for compatible \u003cstrong data-start=\"919\" data-end=\"954\"\u003eGlow-worm Flexicom and Ultracom\u003c\/strong\u003e boiler models that require part number \u003cstrong data-start=\"994\" data-end=\"1008\"\u003e0020023825\u003c\/strong\u003e.
