Danfoss Ignition transformer 052F4034 052F4234

Danfoss ignition transformer, model 052F4034, SKU 052F4234, is designed for use in burner control systems, specifically for the Danfoss EBI4 CM. It operates only during the ignition phase, providing a high-voltage spark to ignite the fuel-air mixture. The transformer has dimensions of 85 mm in length, 65 mm in width, and 35 mm in height, with a net weight of 0.3 kg. It is manufactured in Denmark.

When selecting an ignition transformer of this type, ensure the primary voltage, secondary voltage and current, duty cycle, mounting configuration, terminal type, and connector pattern match the original part. Check the markings on the existing unit to confirm the correct article number. Inspect the ignition cable for leaks or hardening, as these can cause arcing to earth, and verify the electrode gap before condemning the transformer.

Common failure modes include internal short circuits or open windings, leading to no spark or weak spark. The burner may fail to ignite or cycle intermittently. Check the transformer's output with a suitable tester, and inspect the ignition cable and electrode gap for issues that might mimic transformer failure.
