ClimateMaster Thermistor Sensor

The ClimateMaster Thermistor Sensor is a replacement HVAC temperature sensor (also called a temperature probe or thermistor) designed for ClimateMaster geothermal and water-source heat pump equipment. A thermistor is a resistor whose resistance changes with temperature. The unit's control board reads that change to monitor system temperatures.

Key Features:

• Thermistor-based temperature sensing for accurate readings in heating and cooling systems
• Supplies temperature data to the unit controls to support system operation and protection functions
• Made as a replacement part for ClimateMaster equipment
• Compact sensor design that suits typical heat pump service replacement

A faulty thermistor can cause inaccurate temperature readings, fault codes or nuisance lockouts. Replacing it with a ClimateMaster sensor helps restore proper control and dependable operation of your heat pump system. Select the correct part number for your application from the available options.
