Description
The National Comfort Products 14260023 Defrost Sensor is a temperature-sensitive control component used in heat pump systems to detect frost conditions on outdoor evaporator coils. It is installed within the defrost control circuit, where it continuously monitors coil temperature during heating operation. When conditions indicate ice buildup the sensor signals the control board to initiate a defrost cycle, temporarily reversing system operation to clear frost and restore heat transfer efficiency in HVAC systems. The outdoor unit’s defrost management assembly supports maintaining heating performance, protecting coil integrity and ensuring stable operation in conditions.
