Lochinvar & A.O. Smith 100111010 Control

Lochinvar & A.O. Smith 100111010 Control

The Lochinvar & A.O. Smith 100111010 Electronic Control is a critical integrated component designed for high-efficiency commercial water heater systems, specifically engineered for the SUF300N model series. As a veteran-grade HVAC replacement part, this SUF300N control board manages the complex sequence of operations, including ignition timing, flame sensing, and blower speed regulation. It serves as the central intelligence for condensing water heaters, ensuring precise modulation to maintain optimal combustion ratios and thermal efficiency. When performing a water heater control board replacement, this genuine OEM electronic control provides the necessary digital architecture to interface with thermal sensors and gas valves, mitigating the risk of nuisance lockouts commonly found with generic aftermarket alternatives.

Key Benefits

  • Precise Modulation Control: Regulates blower speeds and firing rates to ensure the unit operates at maximum condensing efficiency.
  • Advanced Diagnostics: Integrates with the LCD user interface to provide real-time fault codes and operational status for faster troubleshooting.
  • Combustion Integrity: Continuously monitors flue temperature sensors and flame rectification to prevent unsafe operating conditions.
  • Direct OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith SUF series units, ensuring a seamless plug-and-play fit without modifying high-voltage wiring harnesses.

Common Questions

What are the symptoms of a failing 100111010 control board?
Common indicators include intermittent loss of flame signal, failure of the blower motor to initiate the pre-purge cycle, or persistent "PCB Hardware Fault" error codes on the display. Before replacement, always verify incoming line voltage and check for secure harness connections.

Can this board be used in BTH series models?
While many Lochinvar and A.O. Smith controls look identical, the 100111010 is specifically programmed for the SUF300N parameters. Using a control board with incorrect firmware for your specific BTU input or model series can lead to improper combustion or system damage. Always match the part number to the appliance rating plate.

How do I resolve an E10 or E19 error after installation?
An E10 code typically points to an air switch issue, while E19 relates to the flue sensor. If these persist after installing a new 100111010 control, check the sensor resistance and ensure the vent piping is clear of obstructions, as the board is likely reading an external fault accurately.
