Brahma Ignition transformer TC2LTCAF 15910460

The Brahma Ignition transformer TC2LTCAF (SKU 15910460) is a component used to generate the high-voltage spark that ignites fuel in gas or oil burners. It steps up the mains supply voltage to a level that produces a spark across the ignition electrode gap. This transformer operates only during the ignition phase of the burner sequence, under command from the burner control. It is designed for precise control of gas burner valves, providing opening and closing when voltage is applied, with high heat resistance and durable insulation. The model TC2LTCAF is part of the Brahma brand and falls under the category of ignition transformers.

When selecting a replacement ignition transformer of this type, key parameters to match include secondary voltage and current, primary voltage, duty cycle, and physical mounting form. The terminal type and connector pattern for the ignition cable must also match the existing assembly. Check that the primary voltage corresponds to the supply available on the burner (230 V is common, but 110 V and 24 V versions exist). The ignition cable should be silicone-insulated to withstand high voltage and heat.

Typical failures of ignition transformers include internal short circuits or open windings, leading to no spark or weak spark. A hardened or cracked ignition cable can leak spark to ground, which may mimic a faulty transformer. Symptoms on the equipment include failure to ignite, intermittent ignition, or burner lockout. Check the transformer's output voltage and the condition of the ignition cable before replacing the transformer.
