Lochinvar & A.O. Smith 100208476 Kit
The Lochinvar & A.O. Smith 100208476 Kit is a critical low volt control board kit engineered specifically for high-efficiency outdoor Crest OFN(L) 751-2001 heating boilers. This OEM replacement control board manages primary low voltage operations, ensuring seamless communication between the SMART SYSTEM control module and peripheral safety devices. Designed for precision HVAC troubleshooting, the board features designated terminals for terminals 1-16, facilitating organized field wiring and reliable signal distribution for ignition and safety loops. As a veteran-grade boiler part, it is built to survive the high-demand cycling of industrial or large-scale residential heating systems. When executing a furnace repair or boiler overhaul, using this 100208476 kit maintains the integrity of the original equipment specifications, preventing nuisance shutdowns often caused by non-compatible aftermarket boards. This assembly is standard for Lochinvar Knight XL and A.O. Smith commercial water heating applications where stable HVAC controls are non-negotiable for system uptime.
Key Benefits- Optimized Compatibility: Purpose-built for Outdoor Crest OFN(L) models, ensuring a drop-in low voltage interface without wiring modification.
- Terminal Precision: Clearly labeled schematic for terminals 1-16 simplifies HVAC technician installation and speeds up diagnostic testing.
- OEM Reliability: Genuine Lochinvar & A.O. Smith hardware ensures safety protocols and communication timings remain within factory boiler specifications.
- System Stability: Resolves intermittent low voltage signal loss, protecting sensitive downstream components from erratic power surges.
Which specific models does this kit support?
This kit is designed for the Outdoor Crest OFN(L) 751-2001 series. Always verify your specific model number against the manufacturer’s technical manual before ordering.
Does this board handle high-voltage ignition?
No, this is a low volt control board. It manages the logic and signal path for the 24V circuit, not the primary line voltage or high-tension spark.
Can I use this to replace terminals 17-40?
Negative. This specific kit is mapped only for terminals 1-16. If you are servicing the higher terminal range, you likely need part number 100208481.
