      If the power light is off, ensure the unit is receiving power. Also, close the disconnect switch and check for continuity. An electrician should inspect the electrical connections. Verify the unit operates within the minimum and maximum temperature ranges. Clean the condenser and ensure there's adequate airflow.

      To address water downstream, blow out the system with dry air. Also, check the valve positions and ensure correct connections. Insulate or heat trace air lines exposed to low ambients, or use dry air to lower the dew point. Consider installing a separator ahead of the dryer.
