Fida Compact ignition transformer TE084D

This compact ignition transformer is a step-up unit that raises mains voltage to a level sufficient to create a spark at the ignition electrode gap. It operates exclusively during the ignition phase, under command from the burner control. The housing is a compact unit, and the high-voltage ignition cable is silicone-insulated to withstand heat and voltage stress.

Parts of this type are selected by secondary voltage and current, primary voltage (230 V is common, with 110 V and 24 V versions also available), duty cycle, mounting style, terminal type, and cable connector pattern. When replacing such a transformer, ensure the electrical ratings match the burner control and that the mechanical dimensions and connector layout are compatible. The high-voltage ignition cable must be silicone-insulated; always inspect it as part of the replacement procedure.

A hardened or cracked ignition cable can leak the spark to earth, producing symptoms that mimic a faulty transformer. The burner may fail to ignite or show intermittent ignition issues. Always inspect the cable and its insulation for damage before condemning the transformer.
