Fida Ignition transformer TE041D

The Fida Ignition transformer TE041D is a component designed for use with Fida Compact 5/18PM burners. It provides high-voltage ignition sparks to initiate combustion in gas or oil burners. The transformer features silicone cable insulation and insulated secondary wiring for electrical safety. It operates under the control of the burner's ignition system, energizing only during the ignition phase.

When selecting a replacement ignition transformer of this type, verify the primary voltage (commonly 230 V, but also 110 V or 24 V), secondary voltage and current, duty cycle, mounting configuration, terminal type, and high-voltage cable connector pattern. Ensure the physical dimensions and mounting holes align with the existing bracket, and that the high-voltage connector matches the cable to the electrode. Always confirm compatibility with the specific burner model before ordering.

Typical failures of ignition transformers include cracked or hardened high-voltage cables, which can cause spark leakage to ground, leading to weak or absent ignition. Internal short circuits may result in no spark output, while overheating can cause intermittent operation. Check the cable insulation for damage, measure secondary voltage with a suitable tester, and inspect connections for corrosion or looseness.
