Alpha 1.021762 NTC Temperature Sensor (Replaces 1.015970)

Description

Alpha 1.021762 NTC Temperature Sensor (Replaces 1.015970)

The Alpha 1.021762 NTC Temperature Sensor is a replacement temperature sensor designed for a wide range of Alpha boilers.

This part supersedes the earlier Alpha part number 1.015970 and is used to monitor water temperature within the boiler. The sensor continuously communicates with the PCB, helping the boiler regulate heating and hot water output efficiently and safely.

A faulty NTC sensor can cause inaccurate temperature readings, heating faults, hot water problems, boiler lockouts, or intermittent operation. Replacing a defective sensor can restore reliable boiler performance and improve overall efficiency.
