Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit won't turn on | Power issue, circuit breaker tripped | Check power supply, reset circuit breaker, ensure proper voltage |
| Poor cooling/heating | Dirty filters, blocked airflow, low refrigerant | Clean filters, clear obstructions, check for refrigerant leaks |
| Water leaking indoors | Clogged drain, improper installation slope | Clear drain line, ensure proper downward slope of drain hose |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten all fasteners, clear debris, check installation stability |
| Unit freezing up | Dirty filters, low airflow, low temperature setting | Clean filters, check airflow, increase temperature setting |
| Remote not working | Dead batteries, signal obstruction, distance | Replace batteries, ensure line of sight, move closer to unit |
