Lochinvar & A.O. Smith 100287156 Sensor
Ensure your high-efficiency condensing boiler or water heater maintains optimal operation with the Lochinvar & A.O. Smith 100287156 Flue Temp Sensor Kit. This genuine OEM flue temperature sensor is engineered to provide precise thermal feedback to the integrated control board, preventing hazardous heat buildup and potential heat exchanger damage. Designed for a broad range of Lochinvar Knight and A.O. Smith Cyclone models, this thermistor-based sensor monitors exhaust temperatures in real-time, allowing for accurate modulation and system safety shutdowns when parameters are exceeded.
A faulty or corroded sensor can lead to unexpected HVAC error codes or inefficient cycling. This 100287156 sensor kit includes the sensor itself and the critical sealing grommet to ensure a leak-proof installation in the exhaust assembly. As a direct replacement flue sensor for Lochinvar, it simplifies field repairs by ensuring 100% mechanical and electrical compatibility. For professional contractors, installing genuine Lochinvar boiler parts is the only way to maintain the combustion integrity and factory-rated efficiency of condensing water heaters and hydronic boilers.
Key Benefits- Precision Thermal Monitoring: Provides accurate NTC thermistor readings to the controller for flue gas temperature management.
- System Protection: Triggers safety lockouts if exhaust temperatures reach critical levels, protecting the venting and heat exchanger.
- OEM Compatibility: Exact replacement for A.O. Smith 100287156, ensuring proper fitment across multiple commercial and residential platforms.
- Complete Kit: Includes the flue sensor grommet to prevent exhaust bypass and maintain a secure seal in the manifold.
What are the signs that my flue temperature sensor needs replacement?
Common indicators include specific burner control lockout codes (such as "Flue Temp High"), intermittent ignition failure, or visible corrosion on the sensor tip from condensate exposure.
Is the grommet necessary for the 100287156 sensor installation?
Yes, the grommet is vital for maintaining a gas-tight seal at the flue connection. It prevents flue gases and condensate from escaping into the cabinet, which is why this complete flue temp sensor kit is the preferred service solution.
Can I use a generic thermistor instead of the OEM 100287156?
Generic sensors often lack the specific resistance-to-temperature curve required by Lochinvar and A.O. Smith controls. Using anything other than an OEM heater sensor can lead to improper modulation or failure to trip during a high-heat event.
