16.1.1  Relationship Between the Condition of the Air Conditioner and Pressure and 

Electric Current 

 

Cooling Mode 

Condition of the  

air conditioner 

Low Pressure 

High Pressure 

Electric current during operation

Insufficient refrigerant 

(gas leakage) 

 

 

 

Clogged capillary tube or 

strainer 

 

 

 

Short circuit in the indoor unit 

 

 

 

Heat radiation deficiency 

of the outdoor unit 

 

 

 

Inefficient compression 

 

 

 

•  Carry out the measurement of pressure, electric current, and temperature fifteen minutes after an operation is started. 

 

16.1.2  Diagnosis Methods of a Malfunction of a Compressor 

Nature of fault 

Symptom 

Insufficient compressing of a compressor 

•  Electric current during operation becomes approximately 20% lower than the normal value. 
 
•  The discharge tube of the compressor becomes abnormally hot (normally 70°C to 90°C). 
 
•  The different between high pressure and low pressure becomes almost zero. 

Locked compressor 

•  Electric current reaches a high level abnormally, and the value exceeds the limit of an  
   ammeter. In some cases, a breaker turns off. 
 
•  The compressor has a humming sound.
