Lennox 26G10 Defrost Sensor Built for the rigors ofThe Lennox 26G10 Defrost Sensor is a critical thermistor based control designed for precision management of the defrost cycle in residential Lennox heat pump units. Engineered to monitor the outdoor evaporator coil temperature, this sensor triggers the defrost sequence to prevent excessive ice buildup that can choke airflow and degrade system efficiency. This specific model features an L70 35F temperature rating, meaning it is calibrated to open at
