Fida Ignition transformer TF084D

The Fida Ignition transformer TF084D is a component for burner ignition systems, designed to step up the mains voltage to generate a spark at the ignition electrode. It operates with a supply voltage of 230 V and produces a secondary voltage of 8 kV. The transformer is energized only during the ignition phase, under command from the burner control, and is protected against dust and moisture. It features a silicone-insulated ignition cable with a maximum length of 400 mm. This model is compatible with the Fida Compact 8/20PM burner.

When selecting a replacement ignition transformer of this type, confirm that the primary and secondary voltage ratings match the original part, and that the mounting and connector arrangement are compatible. The transformer is typically mounted using plugs for electrical connection, and the ignition cable must be silicone-insulated to withstand high voltage and heat. Verify the physical dimensions and mounting method to ensure a proper fit.

Common failure modes for ignition transformers of this kind include cracked or hardened ignition cables, which can leak the spark to earth and imitate a faulty transformer. If the transformer fails, the burner may not ignite or may shut down during operation. Check the condition of the ignition cable and electrode before concluding that the transformer itself is defective.
