First diagnostic step

Check that the evaporator thermistor is connected to the sealed system tubing. If the thermistor is plugged in, ensure that it is fully connected to the control box. Check the resistance of the thermistor. If the thermistor checks good, look for a frost pattern on the evaporator plate as the unit may be low on refrigerant.
