CURRENT DETERMINATION REMEDY
TEMPERATURE DIFFERENCE
8°C and over as specified nothing wrong • none
8°C and over higher than specified nothing wrong, outdoor • improve heat radiation
temperature is too high, heat
radiation is not efficient.
under 8°C higher than specified something is preventing heat • excessive amount of refrigerant
radiation • improve heat radiation
under 8°C lower than specified leakage of refrigerant or • locate repair leak
refrigerant system is blocked • flush refrigeration cycle
under 8°C higher than specified by 50% compressor defect • replace the compressor
* Note: Room air humidity is relatively higher, the Temp. difference will be smaller.
