Description
The Carrier 390001921 Outdoor Coil Sensor used in AC and heat pumps. Used for the functioning and effectiveness of the system because it constantly observe the temperature of the outdoor coil. This temperature data is received by the control board of the system and this data is used to control the flow of the refrigerant. One of the main functions of the sensor is to maintain the efficient temperature of the refrigerant which can eventually protect it from either freezing or overheating. This is a small 1.2″ x 5.5″ x 1.3″ sensor that can withstand outdoor conditions.
