Understanding Haier AC Error Codes
Haier AC error codes are displayed when your unit detects a fault. These codes help identify the exact problem so you can fix it quickly. Most Haier ACs use two main series:
- E Series: Issues related to the indoor unit.
- F Series: Issues related to the outdoor unit or overall system.
Each code points to a specific component or safety protection mechanism.
Haier AC E Series Error Codes
| Code | Description | Solution |
|---|---|---|
| E1 | Indoor temperature sensor malfunction | Check wiring or replace the sensor |
| E2 | Pipe temperature sensor malfunction | Replace the sensor |
| E4 | Indoor EEPROM (memory chip) malfunction | Replace the control board |
| E5 | Anti-frost protection triggered | Check refrigerant levels if in cooling mode |
| E7 | Communication error between indoor & outdoor units | Inspect wiring, check control board, replace faulty parts |
| E8 | Indoor fan motor or PCB error | Tighten connections, inspect motor & PCB, replace if needed |
| E9 | Water flow switch/drainage issue | Clear drain pipe, replace switch if faulty |
| E14 | Indoor fan motor malfunction | Inspect and replace motor if necessary |
Haier AC F Series Error Codes
