Nordyne 903110A Ignitor Kit

The Nordyne 903110A Ignitor Kit is a critical replacement for gas-fired furnace systems, specifically engineered to supersede older part numbers including 903110 and 9031100. This hot surface ignitor (HSI) features an upgraded silicon carbide element designed to withstand the thermal stress of repeated ignition cycles in high-efficiency mobile home furnaces and standard residential air handlers. As a direct-fit Nordyne furnace repair part, it includes the necessary female plug connector to ensure seamless integration with the existing wiring harness, eliminating the need for field splicing or modifications. This kit is a standard mechanical requirement for maintaining reliable combustion in Intertherm and Miller furnaces. Proper resistance checks should be performed during installation to ensure the ignitor assembly matches the voltage requirements of the 120V integrated furnace control board, ensuring consistent ignition and preventing nuisance flame out codes.

Key Technical Benefits

• OEM Compatibility: Direct drop-in replacement for legacy Nordyne 903110 and 9031100 ignitor models.
• Integrated Harness: Pre-terminated with the correct Molex-style plug for rapid field installation.
• Enhanced Durability: Specifically calibrated for high-amperage draw to ensure rapid surface heating for gas valve synchronization.
• Optimized Performance: Engineered for Intertherm and Miller furnace ignition reliability under varying gas pressures.

Common Technical Questions

How do I verify if the 903110A is compatible with my furnace?
Contractors should verify the part number on the existing furnace data plate or cross-reference the 903110 or 9031100 numbers. This kit is the standard updated replacement for these specific Nordyne-sourced components.

Will this ignitor work with 80% AFUE and 90%+ AFUE units?
Yes, as long as the furnace control system specifies the 903110A ignitor kit. It is commonly found in both atmospheric and sealed combustion units across the M1, M7, and CMF model series.

What is the best way to handle the silicon carbide element during installation?
Never touch the black element with bare hands. Skin oils create hotspots that cause premature mechanical failure. Always handle the component by its ceramic base.
