SAFARI STORME MY14

HVAC 42 REFRIGERATION CYCLE TROUBLESHOOTING Sr. No. Possible Cause Remedy 1 Insufficient refrigerant Condition x Air conditioner does not cool effective- ly Symptoms in refrigerant cycle x Pressure on both the high and low pressure sides is low x Air around the air outlet is slightly cold Cause x There is gas leakage in the refrigerat- ing cycle Diagnosis x Insufficient refrigerant in the refrigerat- ing cycle x Refrigerant leakage Countermeasures x Locate the leakage and repair x Recharge refrigerant to the specified amount 2 Excessive refrigerant or insufficient conden- ser cooling . Condition x Air conditioner does not cool effective- ly Symptoms in refrigerant cycle x Pressure on both the high and low pressure sides is high. Cause x Refrigerant is overcharge in the re- frigerating cycle causing poor cooling performance x Condenser cooling performance is poor. Diagnosis x Excessive refrigerant in the refrigerat- ing cycle. x Overcharged refrigerant. Poor condenser cooling performance. Countermeasures x Clean the condenser. x Tighten the fan belt to the correct tension. x Above are all normal check the refrigerant.
