Such problems include insufficient insulation, problem with the power source, malfunction of a compressor and a fan. The normal outlet air temperature and pressure of the refrigeration cycle depends on various conditions, the standard values for them are shown in the table to the right.
15.2. 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 Low Pressure Heating Mode 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 measurements of pressure, electric current, and temperature fifteen minutes after an operation is started.
15.3. Breakdown Self Diagnosis Function
15.3.1. Self Diagnosis Function (Three Digits Alphanumeric Code)
Once abnormality has occurred during operation, the unit will stop its operation, and Timer. Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdown condition, the LED will light up again. In operation after breakdown repair, the Timer LED will no more blink. The last error code (abnormality) will be stored in IC memory. To make a diagnosis 1. Timer LED start to blink and the unit automatically stops the operation. 2. Press the CHECK button on the remote controller continuously for 5 seconds. 3. - - will be displayed on the remote controller display. Note: Display only for - -. (No transmitting signal, no receiving sound and no Power LED blinking.) 4. Press the TEMP or button on the remote controller. The code H00 (no abnormality) will be displayed and signal will be transmitted to the main unit. 5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit. 6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5 seconds or operating the unit for 30 seconds. 8. The LED will be off if the unit is turned off or the button on the main unit is pressed. To display memorized error (Protective operation) status: 1. Turn power on. 2. Press the CHECK button on the remote controller continuously for 5 seconds. 3. - - will be displayed on the remote controller display. Note: Display only for - -. (No transmitting signal, no receiving sound and no Power LED blinking.) 4. Press the TEMP or button on the remote controller. The code H00 (no abnormality) will be displayed and signal will be transmitted to the main unit. The power LED lights up. If no abnormality is stored in the memory, three beeps sound will be heard. 5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit. 6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless 46 pressing the CHECK button continuously for 5 seconds or operating the unit for 30 seconds. 8. The same diagnosis can be repeated by turning power on again.
