Carrier 390002072 Evaporator Coil Sensor

Carrier 390002072 is an integral sensor manufactured exclusively for Carrier air conditioning systems. Also, the evaporator coil sensor acts as a small thermometer for your air conditioning system’s cooling process. The evaporator coil pulls heat from the air inside your home. This sensor uses a thermistor in the measurement of the coil temperature. When the coil is cold, the resistance increases which the AC system measures to know the condition of the sensor. When the temp of the coil is understood, the system can adjust the compressor’s performance to cool effectively without using energy wastefully.
