Lochinvar & A.O. Smith 100109676 Adapter
The Lochinvar & A.O. Smith 100109676 Adapter is a critical OEM replacement part designed for field technicians servicing high-efficiency water heaters and boiler systems. This 4-pin to 5-pin adapter bridges the gap between different generations of control components, typically required when upgrading a hot surface ignitor or gas valve assembly on units like the A.O. Smith BTN 80 and BTN 100 or compatible Lochinvar Knight series. In the field, you will encounter this need when a replacement electronic control board or ignition component utilizes a 5-pin harness, while the existing chassis wiring remains a 4-pin configuration. This wire harness adapter eliminates the need for manual splicing or terminal pinning, ensuring a secure, low-resistance electrical connection that maintains the integrity of the flame rectification signal and ignition sequence. Relying on this genuine Lochinvar part ensures that your repair meets factory specifications for voltage and signal continuity in modern HVAC control systems.
Key Benefits
- Seamless Integration: Converts 4-pin to 5-pin connectors without requiring wire stripping or field soldering.
- OEM Compatibility: Specifically engineered for Lochinvar and A.O. Smith commercial and residential heating equipment.
- System Reliability: Precision-molded connectors prevent loose contacts that lead to nuisance lockout codes or ignition failure.
- Versatile Application: Frequently used in gas water heater and boiler control upgrades to maintain factory safety standards.
Common Questions
Will this work with third-party ignitors?
This adapter is specifically designed for genuine OEM components. While it physically adapts the pin configuration, always verify that the voltage and current ratings of the new component match the original system requirements.
Do I need this for all Lochinvar control board replacements?
No, this is specifically for transition scenarios where the ignition harness or gas valve has moved to a 5-pin standard while the internal wiring remains 4-pin. Check your part numbers before ordering.
Can this adapter be used for reversing 5-pin to 4-pin?
No, this is a directional 4-pin to 5-pin adapter. Forcing a connection in reverse can damage the control board or ignition module.
