Description
The Lennox 22J07 Suction Pressure Sensor Thermistor is a temperature-sensitive sensing component used to monitor suction-side conditions in refrigeration and air conditioning systems. It measures changes in line temperature and converts them into resistance signals that are interpreted by the system’s control board for performance regulation. This is commonly installed in residential and light commercial HVAC equipment, where it supports compressor protection, refrigerant flow control, and operational efficiency. By providing exact feedback from the suction circuit. It helps maintain stable cooling performance and prevents system stress caused by abnormal operating conditions.
