Lochinvar & A.O. Smith 100312667 Board
The Lochinvar & A.O. Smith 100312667 Service PCP-IEC Board is a critical integrated control component designed for high-efficiency commercial water heaters and boilers. This Blue Board serves as the primary electronic control module, managing ignition sequences, flame sensing, and temperature regulation. It is the direct OEM replacement for 100187861, engineered to restore full functionality to the PCP-IEC ignition system. When diagnosing fault codes or communication errors in Lochinvar Shield or A.O. Smith Cyclone models, technician-grade boards like the 100312667 ensure precise voltage modulation and reliable sensor feedback. This service kit is essential for contractors maintaining system uptime and operational safety in high-demand hydronic applications. Proper installation requires verifying compatibility with the existing wiring harness and ensuring the control board parameters align with specific BTU ratings of the heat exchanger assembly.
Key Benefits for Technicians- Direct OEM replacement ensures exact fitment and communication protocols without field modifications.
- Compatible with a wide range of A.O. Smith and Lochinvar commercial units, streamlining inventory.
- Modernized PCP-IEC Blue Board hardware improves resistance to electrical noise and voltage fluctuations.
- Facilitates accurate HVAC troubleshooting by providing stable diagnostic feedback for service calls.
- Built to handle the high-cycle demands of commercial water heater ignition controls.
How do I confirm if the 100312667 is the correct board for my boiler?
Verify the part number on the existing PCB or cross-reference the 100187861 legacy number. This board is typically utilized in the Lochinvar Shield (SWH) and A.O. Smith Cyclone (BTH) series.
What does the 'Blue Board' designation signify for these units?
The blue color distinguishes this specific PCP-IEC generation from older versions, indicating updated logic firmware for better combustion management and safety monitoring.
Does this control module include the mounting standoffs or wiring harness?
This is the service board only. Technicians should retain the original mounting hardware and inspect the harness for signs of localized overheating before installing the new component.
