Brahma Ignition transformer TB1LVCS 15911208

The Brahma Ignition transformer TB1LVCS 15911208 is an Italian-made component designed for gas burner ignition systems. It steps up the mains voltage to produce a spark across the ignition electrode gap. This model operates under the command of the burner control during the ignition phase. It is categorized as an ignition transformer and is identified by SKU 15911208.

When selecting a replacement ignition transformer of this type, verify that the primary voltage matches the burner's supply (typically 230 V, but 110 V and 24 V variants exist). Ensure the secondary voltage and current requirements are compatible with the burner. Check the mounting dimensions and terminal arrangement, as well as the connector pattern for the high-voltage cable. The ignition cable must be silicone-insulated to withstand high voltage and heat.

Common failure modes for ignition transformers include internal short circuits or open windings, leading to no spark or weak spark. A hardened or cracked ignition cable can leak the spark to earth, which may be mistaken for a faulty transformer. Symptoms include the burner failing to ignite or intermittent ignition. Check the ignition cable for damage before replacing the transformer.
