Weishaupt Ignition transformer W-ZG01/V We603186

The Weishaupt Ignition transformer W-ZG01/V (SKU We603186) is a high-voltage ignition transformer designed for burner equipment. It generates a spark to ignite the fuel-air mixture in gas and liquid fuel burners during startup. The device converts input voltage into a high-voltage pulse, operating only during the ignition phase under burner control. Its housing is made of heat-resistant plastic and metal, and it is intended for installation as part of burner equipment. This model is manufactured in Germany.

When selecting a replacement ignition transformer of this kind, verify the secondary voltage and current, primary voltage (commonly 230 V, but 110 V and 24 V versions exist), duty cycle, mounting geometry, terminal arrangement, and cable connector pattern. Ensure the mounting and terminals match the existing unit to avoid installation issues. Inspect the high-voltage ignition cable for hardening or cracks, as silicone-insulated cables can degrade and cause spark leakage.

Typical failures of ignition transformers include internal short circuits, open windings, or insulation breakdown, leading to weak or no spark. Equipment may fail to ignite, cycle on flame failure, or show intermittent ignition. Check for visible damage, overheating, or a faulty high-voltage cable that may leak spark to earth, mimicking transformer failure.
