Does your Daikin aircon show an Error Code? Are you worried about the error code issue? No worries, Here we mention what kind of error code possibly arises from your Daikin aircon, and what the meaning has on the error codes. Because, when you find the error code details and their meaning, then you can easily know what the problem arises from the error codes. And also you may easily solve it too.
| No | Error Code | Malfunction |
| 1 | A1 | A1 Indicated – PCB Does Not Work |
| 2 | A3 | A3 Indicate – Drain Level might be High (Due to more dirt and dust) |
| 3 | A5 | A5 Indicate – Overheat or Freezing in Indoor unit (Due to dirt in short circuit or Trouble with Sensor) |
| 4 | A6 | A6 Indicate – Fan Motor Error (Due to Improper connection or Overloaded) |
| 5 | A7 | A7 Indicate – Swing Flap Fan Motor Error (Maybe Fault or Loose connection) |
| 6 | AH | AH indicate – Dust Collector Error (Maybe Fault or Dirtier) |
| 7 | AJ | Aj Indicate – Capacity Setting Error (Might be addressed setting Fault) |
| 8 | C3 | C3 Indicate – Abnormal Water level sensor resistance (Might be water level sensor disconnected or Fault) |
| 9 | C4 | C4 Indicate – Abnormal Resistance level of indoor heat thermistor (Due to thermistor disconnect or short-circuited) |
| 10 | C9 | C9 Indicate – The resistance of the indoor unit suction air thermistor is abnormal (Due to disconnection cable or short-circuited) |
| 11 | CE | CE Indicate – Abnormal radiation thermistor resistance (Due to Fault Thermistor or disconnected Cable) |
| 12 | CJ | CJ Indicate – Abnormal remote controller thermistor resistance (The built-in remote has encountered a faulty.) |
| 13 | E0 | E0 Indicate – Outdoor unit protection devices activated (Might be refrigerant piping clogged or Insufficient refrigerant. / Fault compressor or Fan motor) |
| 14 | E3 | E3 Indicate – High pressure to high (The condenser may sort circuit or overloaded) |
| 15 | E4 | E4 Indicate – Low Pressure to High (The refrigerant piping might be clogged or insufficient refrigerant) |
| 16 | E5 | E5 Indicate – Overheating of Compressor (The refrigerant piping might be clogged or insufficient refrigerant or Fault connection) |
| 17 | F3 | F3 Indicate – Outdoor unit discharge temperature is too high (The refrigerant piping might be clogged or insufficient refrigerant or Thermistor Fault) |
| 18 | H9 | H9 Indicate – Abnormal resistance of the outdoor air temperature thermistor (Thermistor might be Fault or Cable disconnection) |
| 19 | J5 | J5 Indicate – Abnormal resistance of the suction pipe temperature thermistor (The pipe thermistor might be fault or thermistor short circuit) |
| 20 | J6 | J6 Indicate – Abnormal resistance of the outdoor heat exchanger thermistor (Faulty thermistor or cable disconnected) |
| 21 | P1 | P1 Indicate – Open Phase power Voltage Imbalance (three-phase) |
| 22 | U0 | U0 Indicate – Suction pipe temperature is too high (the refrigerant piping system may Fault ) |
| 23 | U1 | U1 Indicate – Reverse Phase (Three Phase power supply has been reversed) |
| 24 | U2 | U2 Indicate – Open Phase or Power Voltage Imbalance (Voltage Imbalance in the power supply or Fan Motor Could be too low) |
| 25 | U4 | U4 – Indicate – Communication error between indoor and outdoor units/outdoor and BS units (Interconnection wire or PCB Fault) |
| 26 | U5 | U5 Indicate – Communication error between indoor unit and remote controller (Interconnection wire or PCB Fault (remote controller) |
| 27 | UA | UA Indicate – Combination error of indoor/BS/outdoor unit, setting error of PCB at the site (Incorrect combination of indoor or Outdoor unit) |
The above-mentioned error code details all indicate some issues in the aircon. If your Daikin aircon shows an error code, You should do aircon repair (Troubleshooting) with a professional aircon repair service company. Cool Care will do aircon troubleshooting with the help of experienced technicians.
