Danfoss Ignition transformer EBI4 052F4031

The Danfoss EBI4 ignition transformer, SKU 052F4031, is a component designed to ignite the combustible mixture in a burner by generating a high-voltage electric arc between ignition electrodes. It operates with a supply voltage of 220 V, a frequency range of 50–60 Hz, and consumes 60 W of power. The transformer provides an ignition current of 40 mA and draws a current of 0.25 A. This model supersedes part numbers 052F0036 and 0005020057.

When selecting a replacement ignition transformer of this kind, verify that the primary voltage, frequency, and power ratings match the burner's control system. The transformer must also match the mounting pattern, terminal configuration, and cable connector type of the original. Check the secondary voltage and current requirements of the ignition electrode assembly to ensure compatibility. Always inspect the condition of ignition cables and electrodes before installation, as damaged cables can cause spark leakage.

Typical failures of ignition transformers include internal short circuits or open windings, leading to no spark at the electrodes. The burner may fail to ignite, causing the control to lock out after the safety time. External symptoms can include visible damage to the transformer casing or burnt terminals. Before replacing the transformer, check the ignition cables and electrode gap for faults, as these can mimic transformer failure.
