Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power supply issue, circuit breaker tripped, remote control batteries dead | Check power connection, reset circuit breaker, replace remote batteries |
| Poor cooling/heating performance | Dirty filters, low refrigerant, blocked airflow, incorrect thermostat setting | Clean filters, check refrigerant charge, clear obstructions, verify settings |
| Water leakage from indoor unit | Clogged drain line, improper installation slope, damaged drain pan | Clear drain line, ensure proper slope, inspect and replace drain pan if needed |
| Unusual noises during operation | Loose parts, debris in fan, compressor issues, vibration from mounting | Tighten all fasteners, clean fan blades, check compressor, secure mounting |
| Ice formation on coils | Low refrigerant, dirty filters, restricted airflow, faulty defrost system | Check refrigerant level, clean filters, ensure proper airflow, test defrost cycle |
| Frequent cycling on/off | Oversized unit, thermostat location, dirty condenser, electrical issues | Verify unit sizing, relocate thermostat, clean outdoor unit, check electrical connections |
