What causes low exhaust pressure in a Vertiv Liebert CR045 Air Conditioner?
- LLogan BerrySep 12, 2025
Low exhaust pressure in your Vertiv Air Conditioner can be caused by a refrigerant leak. Locate the leakage point, repair it, and add refrigerant. Another cause could be a faulty fan speed controller of the outdoor unit, where the output voltage remains at 100% regardless of changes in condensing pressure. If the fan speed controller is faulty, it should be replaced.
