Lochinvar & A.O. Smith 100278114 Sensor
As a seasoned technician, you know that accurate temperature feedback is the backbone of any high-efficiency condensing boiler or water heater. The Lochinvar & A.O. Smith 100278114 Sensor is a critical 10k Ohm NTC thermistor designed for precision Domestic Hot Water (DHW) monitoring. This genuine OEM replacement part ensures the control board receives real-time resistance data to modulate firing rates and maintain setpoint stability. Whether you are servicing a Lochinvar Knight CCN120 or an A.O. Smith industrial unit, utilizing this specific sensor prevents the short-cycling and erratic temperature swings associated with generic aftermarket alternatives. The 1/8-inch BSPT threading and robust lead wire construction are engineered to withstand the thermal stresses of high-demand hydronic environments, ensuring your call-backs are non-existent and the system’s energy efficiency remains at peak levels.
Key Benefits:
- OEM Reliability: Direct replacement for 100278114, ensuring 100% compatibility with Lochinvar and A.O. Smith control logic.
- Enhanced Precision: High-accuracy 10k thermistor technology provides stable DHW temperature monitoring for consistent user comfort.
- System Protection: Critical for prevents overheating and ensuring the thermal limit integration functions correctly within the water heating loop.
- Professional Grade: Built to original manufacturer specifications, meaning it fits the immersion well perfectly without the need for field modifications.
Common Questions:
How do I test the 100278114 sensor?
Using a multimeter set to Ohms, measure the resistance across the two leads. At 77°F (25°C), a functional sensor should read approximately 10,000 Ohms. Significant deviations from the standard resistance chart indicate a faulty thermistor that requires replacement.
Will this sensor fix an "Open Sensor" or "Short Sensor" error code?
Yes, those codes typically trigger when the control board detects an infinite or zero-resistance path. Replacing the faulty DHW sensor with this OEM 100278114 part is the standard procedure for clearing these diagnostic faults.
Can I use this for both Lochinvar and A.O. Smith units?
This part is the official cross-referenced sensor for both brands, specifically designed for their mid-to-high capacity boiler and water heater lineups. Always verify your specific model number before installation.
