Description
Lochinvar & A.O. Smith General Lower Thermistor Replacement (100263932)
Keep your Lochinvar or A.O. Smith water heater or boiler operating at peak efficiency with the OEM-specified General Lower Thermistor Replacement, part number 100263932. This thermistor is engineered to provide precise lower-zone water temperature sensing, ensuring your unit’s control system receives accurate feedback for safe, efficient, and reliable operation.
Product Overview
The lower thermistor plays a critical role in monitoring water temperature in the lower section of the storage tank or heat exchanger. When the thermistor fails or degrades, the control board loses accurate temperature data — leading to inefficient heating cycles, nuisance faults, or potential safety shutdowns. Replacing a worn or faulty thermistor with this genuine OEM part restores proper system communication and performance.
