Description
The Heatcraft Refrigeration 89904903 Temperature Sensor Kit is a refrigeration temperature sensing component used in an electronic control system to monitor evaporator or cabinet temperatures. It is installed with IntelliGen coolant in HVAC systems, where it connects to the controller to provide temperature response for system regulation. The sensor help the control board adjust cooling cycles, valve operation, and defrost timing based on measured conditions. It is commonly used in refrigerant units such as cold rooms, display cases, and walk-in coolers to ensure accurate temperature control and stable system performance in varying load conditions.
