When the temperature decreases, the resistance becomes higher. Therefore, the present flow within the thermistor represents the present temperature. Because it have high thermal sensitivity, small in size and sturdy against shock. They are used in various products supporting our daily lives. And one of them is in an Aircon. An AC makes the room cooler by absorbing heat and supplying cool air with the evaporator coil. It discharges the absorbed heat through the outdoor unit. In order to control temperature, thermistors are used in both indoor and outdoor units. It is sometimes referred to as temperature sensor. Aircon thermistor price depends on type. And the cost of Aircon thermistor replacement depends on model and difficulty in replacement.

Indoor Ac thermistor
This is the thermistor that is found in the Indoor unit. It is used to control the temperature from the evaporator coil. As mentioned earlier, this is the thermistor used to measure coil temperature.
Outdoor thermistor
This is found inside the outdoor unit, it is attached to the end of the copper tube. This thermistor is connected to the main control board in the outdoor unit. If the resistance it measures falls out of the range or spectrum. It will indicate to the motherboard that it is faulty. And this will in turn cause an error code to be displayed.

If the number of blinking light indicates that the thermistor is faulty. It will then have to be replaced. If it is a Daikin Aircon instead, the error code will be indicated on the Aircon remote control instead.
By measuring the resistance using a Multimeter :
There are times when the thermistor fails to indicate to the control board that it has malfunctioned. This can be due to faulty electrical ends of the wire. Hence, if you were to suspect that the thermistor is faulty. Simply use a multimeter to check on the resistance value of the thermistor.
