Lennox 97M60 Defrost Sensor

The Lennox 97M60 Defrost Sensor is a vital part of Lennox HVAC systems responsible for preventing ice buildup on the evaporator coil. It acts as a temperature monitor, constantly measuring the surrounding air. When the temperature falls within a range typically between -40°C and 50°C, with an accuracy of ±5%, the sensor triggers the defrost cycle. This cycle melts any accumulated ice, ensuring optimal airflow and efficient operation of your Lennox system. Without this sensor, ice buildup would restrict airflow, reducing heating capacity and potentially damaging the equipment. In short, the 97M60 defrost sensor helps your Lennox system stay ice-free and function at its best.
