Fida Ignition transformer TF082D1

The Fida Ignition transformer TF082D1 is a compact, sealed-housing component designed for gas boilers and burners. It operates on a 230 V supply at 60 Hz, delivering a secondary voltage of 4 kV and a secondary current of 20 mA. The transformer features a plug connector, two removable brackets for mounting, and a silicone-insulated ignition cable. It is energized only during the ignition phase and meets European safety requirements.

Parts of this type are selected by matching primary voltage, secondary voltage and current, duty cycle, mounting arrangement, terminal type, and ignition cable connector pattern. Verify the mounting footprint and terminal layout against the existing bracket and wiring. Ensure the primary voltage (commonly 230 V, but 110 V and 24 V variants exist) and secondary output match the burner design. Check the condition of the ignition cable and electrode before replacing the transformer.

Typical failures include cracked or hardened ignition cables that leak spark to earth, mimicking a faulty transformer. Contaminated or eroded electrodes may prevent spark formation even with a healthy transformer. When the transformer fails, the burner may not ignite or may shut down during the ignition sequence. Inspect the cable and electrode first to avoid unnecessary part replacement.
