TCL AC Error Codes: Complete Troubleshooting Guide for Pakistan
Table of Contents
If your TCL Inverter Air Conditioner stops cooling and displays a code like “E1” or “E2” on the indoor panel, it is telling you exactly what is wrong. Knowing these codes can help you fix simple issues yourself or explain the problem clearly to a technician.
Below is the comprehensive list of error codes for TCL DC Inverter ACs.
Common “E” Error Codes #
| Error Code | Possible Cause | Solution |
|---|---|---|
| E0 | Communication Error (Indoor/Outdoor units not talking). | Check the wiring connecting the indoor and outdoor units. Restart the AC. |
| E1 | Room Temperature Sensor Fault. | The sensor measuring room heat is loose or broken. Needs replacement. |
| E2 | Indoor Pipe/Coil Sensor Fault. | The sensor inside the copper coil is faulty. Call a technician. |
| E3 | Outdoor Pipe/Condenser Sensor Fault. | Issue with the sensor in the outdoor unit. |
| E4 | System Abnormality (Refrigerant/Gas Issue). | Often means low gas (leakage) or blockages in the pipe. |
| E5 | Model Configuration Error. | Usually a PCB board issue where settings are mixed up. |
| E6 | Indoor Fan Motor Fault. | The blower fan is stuck or the motor has failed. |
| E9 | Outdoor Inverter Module Issue. | Problem with the main outdoor PCB board (IPM). |
Common “P” Protection Codes #
If you see a “P” code, it often means the AC is protecting itself from damage.
- P0: Module overheating (Outdoor unit is too hot or dirty).
- P1: Voltage too high or too low (Check your stabilizer).
- P2: Over-current protection (Compressor drawing too much power).
- P4: Compressor discharge temperature too high.
