18.4.24  F95 (Outdoor High Pressure Protection: Cooling or Soft Dry) 
Malfunction Decision Conditions 
  During operation of cooling or soft dry, when outdoor unit heat exchanger high temperature data is detected by 
the outdoor unit heat exchanger thermistor. 
 
Malfunction Caused 
  Outdoor heat exchanger temperature rise due to short-circuit of hot discharge air flow. 
  Outdoor heat exchanger temperature rise due to defective of outdoor fan motor. 
  Outdoor heat exchange temperature rise due to defective outdoor heat exchanger thermistor. 
  Outdoor heat exchanger temperature rise due to defective of outdoor unit PCB.

18.4.25 F96 (IPM Overheating) 
Malfunction Decision Conditions 
  During operating of cooling and heating, when IPM temperature data (100°C) is detected by the IPM temperature 
sensor. 
Multi Models only 
o  Compressor Overheating: During operation of cooling and heating, when the compressor OL is activated. 
o  Heat Sink Overheating: During operation of cooling and heating, when heat sink temperature data (90°C) is 
detected by the heat sink temperature sensor. 
 
Malfunction Caused 
  IPM overheats due to short circuit of hot discharge air flow. 
  IPM overheats due to defective of outdoor fan motor. 
  IPM overheats due to defective of internal circuitry of IPM. 
  IPM overheats due to defective IPM temperature sensor. 
Multi Models Only 
o  Compressor OL connector poor contact. 
o Compressor 
OL 
faulty.

18.4.26  F97 (Compressor Overheating) 
Malfunction Decision Conditions 
  During operation of cooling and heating, when compressor tank temperature data (112°C) is detected by the 
compressor tank temperature sensor. 
 
Malfunction Caused 
  Faulty compressor tank temperature sensor 
  2/3 way valve closed 
 Refrigerant 
shortage 
(refrigerant leakage) 
  Faulty outdoor unit PCB 
 Faulty 
compressor
