Trane CNT1170 Defrost Control 30067439-890 it is engineered to senseThe Trane CNT1170 Defrost Control is a critical OEM replacement part designed for precision management of the defrost cycle in high efficiency heat pump systems. This SPST (Single Pole Single Throw) control utilizes a 70Op 37Cl calibration, specifically engineered to open at 70F and close at 37F. By accurately monitoring the evaporator coil temperature, the CNT1170 prevents excessive ice accumulation that can lead to reduced airflow and potential
