Kromschroder Ignition transformer TGI 5-15/100WE 84391250

Kromschroder ignition transformer model TGI 5-15/100WE (SKU 84391250) for gas and oil burners and industrial heating systems. It transforms mains voltage to a high voltage to generate an ignition spark across the electrode gap. It receives power via the burner control box and operates only during the ignition phase. Certified to CSA C22.2 No. 13-1962 and complies with the Machinery Directive 2006/42/EC.

Choose a replacement ignition transformer of this type by comparing secondary voltage and current, primary voltage, duty cycle, mounting style, terminal arrangement, and the connector pattern for the ignition cable. Verify the physical dimensions and mounting hole centres and confirm that the primary voltage and control logic match the burner control box. Also ensure the transformer's duty cycle is appropriate for the ignition sequence; too short a duty cycle may cause overheating in frequently cycling burners.

When an ignition transformer of this type fails, the burner typically will not ignite and no spark appears at the electrode. Internal winding shorts or open circuits are common failure modes. A damaged ignition cable can leak high voltage to earth, producing the same symptom, so always inspect the cable before concluding the transformer is faulty. Operating beyond the specified duty cycle may overheat the transformer and accelerate failure.
