Lochinvar & A.O. Smith 100208566 Sensor
The Lochinvar & A.O. Smith 100208566 Sensor is a critical high limit outlet sensor designed for precise temperature monitoring in high-efficiency hydronic heating and commercial water heater systems. This OEM replacement part serves as an essential safety component, providing the immersion sensor feedback necessary to prevent overheating and ensure stable thermal discharge. Engineered with a G 1/4 NPT thread for a secure, leak-free seat, this K-Stat sensor is a direct match for various Lochinvar Knight and A.O. Smith wall-mount units. For field technicians, this 100208566 temperature sensor is the standard for restoring system safety logic and maintaining energy-efficient boiler operation without the risks associated with generic alternatives.
Key Benefits- Precise High-Limit Protection: Acts as a reliable thermal cut-off to prevent heat exchanger damage from excessive temperatures.
- Seamless Integration: Designed specifically for Lochinvar WA125-WA200 and comparable A.O. Smith series, ensuring accurate control board communication.
- Industrial-Grade Construction: Features a durable brass housing and NPT threading to withstand high-pressure HVACR environments.
- Accurate Signal Continuity: Calibrated to provide consistent resistance values, reducing nuisance tripping and error code faults.
Is the 100208566 sensor compatible with my specific Lochinvar model?
This outlet sensor is optimized for SLA, SNA, and SNR models, as well as WA125 through WA200 wall-mount water heaters. Always verify your specific serial number to ensure a match with the G 1/4 NPT fitting.
What are the symptoms of a failing discharge sensor?
Technicians often see "High Limit" lockout errors or erratic temperature readings on the user interface module. If the sensor resistance does not match the manufacturer's performance curve, the unit may fail to fire or cycle prematurely.
Does this part include the necessary mounting hardware?
The 100208566 is an immersion-style sensor that threads directly into the outlet manifold. Ensure the threads are cleaned and a suitable pipe sealant is used for a pressure-tight installation.
