Lochinvar & A.O. Smith 100208635 Ignition Cable

The Lochinvar & A.O. Smith 100208635 Ignition Cable is a critical OEM spark ignition lead designed for high-performance gas-fired boilers and water heaters. Measuring 48 inches (48") in length, this cable provides the necessary high-voltage pathway from the ignition control module to the spark electrode, ensuring consistent burner light-off. Built to withstand the extreme thermal conditions of a combustion chamber, the high-temperature insulation prevents voltage leakage and dielectric breakdown, which are common causes of ignition failure and "no flame sensed" errors in Lochinvar boiler troubleshooting. This genuine replacement part, which replaces older numbers like WRE2031 and WRE2031-CABLE, is essential for maintaining the sequence of operation in commercial and residential heating systems. For technicians performing a hot surface ignition or spark-to-pilot overhaul, using this HVAC furnace ignition cable ensures the electrical conductivity matches the manufacturer's millivolt and microamp signal specifications for reliable flame rectification.

• Universal Compatibility: Engineered specifically for Lochinvar and A.O. Smith boiler parts, ensuring seamless integration with original control boards.
• Extended Reach: The 48-inch length allows for versatile routing around internal components while maintaining a safe distance from high-heat zones.
• Durable Dielectric Strength: High-grade spark igniter wire insulation prevents arcing to the chassis, reducing intermittent lockouts.
• OEM Precision: Direct replacement for Lochinvar 100208635, eliminating the need for field modifications or generic "cut-to-size" leads.

What causes a Lochinvar ignition cable to fail?
Most failures result from heat-induced brittleness or carbon tracking on the insulation, which leads to weak spark delivery or grounded signals before they reach the electrode.

Is the 100208635 cable compatible with other brands?
While primarily used for Lochinvar and A.O. Smith gas appliances, it is also a cross-reference for specific State and American Water Heaters models. Always verify your specific model number.

Can I trim this wire if the 48-inch length is too long?
It is recommended to loop the excess cable away from heat sources rather than trimming, as field-crimped terminals can increase resistance and compromise ignition system reliability.
