Description
The GREE 3900031302 temperature sensor is a genuine OEM thermistor assembly used in compatible Gree ductless mini-split indoor units. This combination sensor monitors both indoor ambient air temperature and evaporator coil temperature, sending readings to the system control board to regulate cooling, heating, and defrost operation. Accurate sensor feedback allows the HVAC system to maintain proper temperature control and protect the evaporator coil from abnormal operating conditions. This replacement sensor is commonly installed in Gree split system indoor air handlers when a faulty thermistor causes temperature errors or system fault codes.
