Lochinvar & A.O. Smith 100263932 Thermistor
When you're dealing with inconsistent water temps or persistent E5 error codes on a high-efficiency unit, the Lochinvar & A.O. Smith 100263932 Thermistor is the OEM replacement part you need to restore precise temperature regulation. This Negative Temperature Coefficient (NTC) sensor is the general lower thermistor, designed to monitor the bottom of the tank and provide the control board with the real-time data required for accurate burn modulation and thermal stacking prevention. In the field, we see these fail due to sediment buildup or extreme thermal cycling, which causes resistance drift and results in the "temperature sensor failure" or "5-flash" code on many A.O. Smith Cyclone and Lochinvar Knight series models. This genuine 100263932 water heater sensor ensures the thermistor resistance remains within factory spec, preventing premature cycles and maintaining the energy efficiency of the commercial or residential system. Always verify the part number 100263932 against your specific model's manual to ensure compatibility and a proper seal during installation.
Key Benefits:
- Precision Temperature Sensing: Provides high-accuracy resistance data to the controller to maintain a steady setpoint.
- Optimized Compatibility: Replaces older part numbers including 100072102 and 6911177 for streamlined maintenance.
- Industrial Grade Build: Built as a genuine Lochinvar & A.O. Smith part to withstand the harsh environment of a high-firing tank.
- System Reliability: Resolves common thermistor failure error codes that lock out the burner and prevent hot water production.
Common Questions:
What model water heaters use the 100263932 thermistor?
This lower thermistor replacement is engineered for a wide range of products including the A.O. Smith Cyclone (BTH/BTX) series, Lochinvar Knight boilers, and certain State or American Water Heater commercial units.
How do I test if my 100263932 thermistor is bad?
Use a multimeter to check the ohm resistance. At room temperature (approx. 77°F), this NTC thermistor should read near its rated resistance. If the circuit is open, shorted, or the ohms don't shift with temperature changes, it’s time for a replacement.
Does this part include the mounting clip or harness?
This is the 100263932 sensor itself. If your harness is corroded or damaged, you may need to order the 100263933 wiring kit separately to ensure a secure electrical connection to the board.
