line. If so, charge with the correct 
amount of gas. 

 

The refrigerant gas is leaking

the screws that fasten the 
condenser are tightened. 

 

The evaporator and/or condenser 
fans are loose 

Check if the fans are securely 
fastened. Also, check if the fan 
blades are loose, broken or crooked. 
If so, change the faulty blade. 

 

Compressor has an internal noise 

If the noise persists after all other
