Lochinvar & A.O. Smith 100293702 Control Board
The Lochinvar & A.O. Smith 100293702 Control Board is the primary integrated boiler control designed for precise HVAC system management in high-efficiency commercial and residential units. As a direct OEM replacement part, this board is engineered to oversee the full sequence of operation, including ignition control, flame sensing, and temperature regulation. It is a critical component for technicians servicing Lochinvar Power-Fin and A.O. Smith PBL/PBN series boilers, ensuring that safety limits and diagnostic signals are processed with millisecond accuracy.
Replacing a failed circuit board with this genuine Lochinvar 100293702 restores communication between the user interface and system sensors. This main control board features a rugged architecture designed to withstand the thermal stress of modern mechanical rooms. By maintaining strict control over the gas valve and blower speeds, it optimizes combustion efficiency and prevents unnecessary system cycling. Whether you are addressing an HVAC troubleshooting code or performing a full system overhaul, this board provides the reliable logic required for high-demand hydronic applications.
Key Benefits for Contractors:- Direct OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith models, including the PB502-2001 and PF502-2001 series, ensuring a plug-and-play fit without field modifications.
- Advanced Diagnostics: Equipped with onboard LED indicators and microprocessor logic to simplify HVAC fault code identification and reduce labor time.
- Enhanced System Safety: Actively monitors limit switches and flame rectifications to ensure the unit shuts down safely if an unsafe operating condition is detected.
- Precision Performance: Manages complex heating curves and modulation rates to maintain stable discharge temperatures and high fuel economy.
What are the symptoms of a failing Lochinvar control board?
Common indicators include intermittent ignition failure, the blower motor running constantly without a call for heat, or the system failing to respond to 24V signals at the thermostat terminals. If the diagnostic LED remains dark despite confirmed line voltage, the board likely requires replacement.
Is this board a compatible replacement for older A.O. Smith PB series models?
Yes, the 100293702 is the current standard main control board for various PBL and PBN series units. Always verify your specific model number and serial number against the manufacturer’s parts list to confirm exact fitment.
Does this board control the variable speed combustion blower?
Yes, this integrated control manages the signal to the combustion fan, adjusting speeds based on the required modulation rate to ensure the correct air-to-fuel ratio during the start-up and run cycles.
