Neuco 17j57 Electrode Ignitor Gas Furnace

Product Description

The NEUCO 17j57 is an electrode ignitor designed for use in gas furnace applications. The electrode ignitor serves as a critical component in the ignition system, generating the spark that initiates combustion in the heat exchanger. Licensed HVAC technicians install and replace this part during routine maintenance or when a furnace fails to ignite. The ignitor must produce a reliable, consistent spark across the electrode gap to ensure safe and efficient furnace startup each heating cycle.

This electrode ignitor is suited for residential gas furnace systems where spark-style ignition is used in place of hot surface ignition. It is typically installed in low-voltage-controlled ignition circuits and is compatible with furnace models that specify an electrode ignitor assembly. HVAC service professionals encounter this type of component when diagnosing a no-heat call caused by ignition failure.

Key Features

• Spark electrode design for reliable ignition in gas furnace systems
• Direct replacement style for electrode ignitor assemblies

Compatibility

Designed as an OEM-style replacement electrode ignitor for residential gas furnace systems. Referenced in the Lennox and Armstrong product lines under part number 17j57.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always shut off electrical power and close the manual gas shutoff valve before servicing the ignition system. Handle the electrode carefully to avoid bending the electrode tip or disturbing the spark gap. Follow applicable local codes and manufacturer guidelines when reinstalling or replacing ignition components.
