Description
The Velocity Boiler Works (Crown) 240012 NTC Sensor – AH is a genuine OEM-quality replacement temperature sensor engineered for use with Crown and Velocity Boiler Works hydronic boiler systems. NTC (Negative Temperature Coefficient) sensors are critical components in modern boiler controls, providing accurate real-time temperature feedback to the boiler’s control board to ensure safe, efficient, and reliable system operation.
Product Overview
This sensor is designed as a direct replacement for compatible Crown and Velocity Boiler Works boiler models. Proper temperature sensing is essential to boiler performance — a faulty or degraded NTC sensor can result in inaccurate temperature readings, inefficient operation, or system lockout. Replacing it with the correct OEM part restores full system functionality and protects your investment.
Key Features

Why Choose the OEM Replacement?
Using the correct OEM sensor part number ensures compatibility with your boiler’s control board and maintains the accuracy of temperature regulation. Aftermarket substitutes may not match the precise resistance curve of the original NTC thermistor, potentially causing erratic boiler behavior or control faults. The Velocity Boiler Works 240012 sensor is the right part for the job.
