15.4.29    F98 (Input Over Current Detection) 

Malfunction Decision Conditions 

•

  During operation of cooling and heating, when an input over-current (16.8A) is detected by checking the input 

current value being detected by current transformer (CT) with the compressor running. 

 

Malfunction Caused 

•

  Over-current due to compressor failure. 

•

  Over-current due to defective outdoor unit PCB. 

•

  Over-current due to defective inverter main circuit electrolytic capacitor. 

•

  Over-current due to excessive refrigerant.
