2
Ensure drain hose slopes downward - no upward loops
3
Clean drain pan and check for cracks
4
Clear drain line blockage with compressed air or wet/dry vacuum

Inspect for frozen evaporator coil - indicates airflow problem
8
Clean air filters to improve airflow
9
In humid conditions, increase fan speed setting
10
