Brahma Ignition transformer TD1STCAF 15910414

The Brahma Ignition transformer TD1STCAF 15910414 is a component designed to step up the mains voltage to a level sufficient for generating a spark across the ignition electrode gap. It operates only during the ignition phase of the burner cycle, under command from the burner control. The transformer supplies high-voltage, low-current energy to the ignition electrode, initiating the flame. It has a supply voltage of 230 V and features insulated secondary insulation.

Parts of this type are selected by matching the primary voltage to the burner control supply, which is commonly 230 V, but 110 V and 24 V versions exist. Secondary voltage and current determine the spark energy and must be matched to the electrode gap and combustion chamber conditions. Duty cycle, mounting type, terminal configuration, and cable connector pattern are also critical for direct replacement. Before ordering, verify the cable condition and connector compatibility with the existing electrode assembly.

Typical failure modes for ignition transformers include internal short circuits or open windings, often caused by overheating or insulation breakdown. When a transformer fails, the burner may not ignite, or the flame may not be established, leading to a lockout condition. Check the ignition cable for hardening or cracking, as a damaged cable can leak the spark to earth, mimicking a faulty transformer. Also inspect the electrode gap and condition, as incorrect spacing or fouling can prevent spark generation.
