Lochinvar & A.O. Smith 100208550 Limit Switch
Maintain critical system safety and prevent thermal over-run with the Lochinvar & A.O. Smith 100208550 Limit Switch. As a genuine OEM replacement part, this high limit outlet sensor is engineered to provide precise temperature monitoring for commercial and residential water heating applications. Veteran contractors recognize this part by its legacy number TST2061K, designed specifically to integrate with the control logic of high-performance hydronic systems. The 100208550 utilizes a high-accuracy thermistor design to detect temperature spikes, triggering an immediate safety shutdown to protect the heat exchanger and internal components from permanent damage. This outlet high limit switch is a direct drop-in for several Lochinvar SNA and SNR models, ensuring your repairs meet factory specifications without the risk of resistance mismatches common with universal aftermarket sensors. Rely on this A.O. Smith 100208550 sensor kit for consistent thermal regulation and to restore the integrity of the appliance's safety string.
Key Benefits- Direct OEM Compatibility: Engineered specifically for Lochinvar SNA 285, 400, 500, and SNR 150/200 series water heaters.
- Precision Thermal Sensing: High-sensitivity thermistor provides rapid response times to prevent overheating and potential tank failure.
- System Protection: Acts as a critical secondary safety, protecting the heat exchanger from scaling and thermal stress.
- Verified Performance: Replaces obsolete part number TST2061, ensuring compatibility with the latest control board firmware.
What are the symptoms of a failing 100208550 high limit sensor?
Technicians typically see "High Limit" or "Outlet Sensor" lockout codes on the digital display. If the unit cycles shortly after ignition or fails to reach the setpoint despite a clear call for heat, the sensor resistance may be drifting out of spec.
Does this kit include the necessary mounting components?
Yes, this outlet sensor kit is designed for immediate field installation, typically including the high-limit shield or probe assembly depending on the specific model revision.
Is this part interchangeable with the TST2032?
No. While they may look similar, the 100208550 (TST2061K) has a specific resistance curve and temperature trip point calibrated for outlet monitoring rather than general tank temperature sensing.
