Lochinvar & A.O. Smith 100208619 Wire Harness

Integrating the Lochinvar & A.O. Smith 100208619 Wire Harness is a critical step for maintaining signal integrity between the boiler control board and the gas valve. This high-performance gas valve wiring harness is engineered specifically for Lochinvar Knight Boilers (KBN080-285) and Armor AW150-285 condensing water heaters. As a direct OEM replacement wire harness, it eliminates the "G/V Relay Fail" and "No Flame Ign" codes often caused by brittle or intermittent legacy wiring. This revised harness features a heavy-duty moulded rubber connector, replacing older two-piece designs to ensure a moisture-resistant, vibration-proof connection. For technicians troubleshooting intermittent lockout issues, upgrading to the 100208619 harness ensures precise 24V signal transmission and reliable solenoid actuation. This boiler electrical component is essential for safe modulation and consistent ignition cycles in high-efficiency residential and commercial hydronic systems, preventing gas leaks by maintaining strict control over the gas flow sequence.

• Precise Signal Transmission: Ensures the gas control board accurately regulates gas flow to the burner for peak thermal productivity.
• Simplified Installation: Plug-and-play OEM fit minimizes downtime during field repairs on Knight and Armor series equipment.
• Enhanced Durability: Modern fully moulded construction provides superior resistance to heat and humidity compared to older modular versions.
• System Safety: Prevents false flame failure codes and ensures the gas valve shuts down immediately when the control signal is cut.

• Does this harness fix "G/V Relay Fail" errors? Yes, this harness is the primary solution for relay communication errors between the PCB and the gas valve solenoid.
• Is it compatible with older Knight boiler models? It is designed for KBN080 through KBN285 models; always verify your specific serial number for the correct logic board interface.
• Can I use this for non-condensing units? No, this is specifically engineered for high-efficiency condensing boilers and water heaters like the Armor and Knight series.
