Lochinvar & A.O. Smith 100111586 Board
The Lochinvar & A.O. Smith 100111586 Board is a critical OEM replacement part engineered for high-performance boilers and water heaters. As an ON-OFF 1 ELEM LWCO ANODE BOARD, this component serves a dual-purpose role in system protection. It integrates Low Water Cut-Off (LWCO) logic to prevent dry-fire conditions while simultaneously monitoring the electrical resistance of the anode rod. When the board detects that the sacrificial anode has reached its consumption limit, it triggers a diagnostic alert to prevent tank corrosion. This single element control board ensures that the system maintains optimal cathodic protection, extending the service life of the heat exchanger. For contractors, the 100111586 provides a direct-fit solution for A.O. Smith and Lochinvar residential and light commercial units, maintaining factory specifications for safety and efficiency. Replacing a fouled or non-responsive anode LWCO board is essential for preventing expensive scale buildup and structural tank failure.
Key Benefits- Integrated Safety: Combines Low Water Cut-Off protection with active anode rod monitoring in a single PCB.
- Corrosion Mitigation: Prevents premature tank failure by ensuring the anode rod provides consistent cathodic protection.
- Plug-and-Play Compatibility: Designed as a genuine OEM repair part to match original factory wiring and electrical resistance parameters.
- System Reliability: Automated monitoring reduces the risk of undetected low water levels or exhausted sacrificial anodes.
What are the symptoms of a failing 100111586 board?
Common indicators include persistent "Low Water" error codes despite adequate pressure, or failure to recognize a new anode rod installation. Sudden corrosion in the system can also indicate the anode monitoring circuit has failed.
Can this board be used in multi-element systems?
No, the 100111586 is specifically designed for 1-element configurations. For multi-element units, verify the specific part number in the service manual to ensure proper control logic.
Does this board require calibration after installation?
This is a pre-configured on-off control board. It typically functions immediately upon connection to the LWCO probe and anode circuit, though it is standard practice to test the low water cutoff trip point during commissioning.
