Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not starting | Power loss, tripped breaker, faulty thermostat | Check power supply, reset breakers, verify thermostat settings |
| Insufficient cooling | Dirty filters, low refrigerant, blocked condenser | Clean filters, check refrigerant charge, clear condenser area |
| Unit freezing up | Low airflow, dirty coils, low refrigerant | Check filters and blower, clean coils, verify refrigerant charge |
| Unusual noises | Loose parts, failing motor, debris in fan | Tighten all fasteners, inspect motors, clear fan area |
| Water leakage | Clogged drain line, improper slope, pump failure | Clear drain line, ensure proper slope, check condensate pump |
| Short cycling | Dirty filters, incorrect sizing, faulty sensor | Clean/replace filters, verify system sizing, check sensors |
