What causes low exhaust pressure in a Vertiv Liebert CR045 Air Conditioner?
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.
What does it mean if the suction and exhaust pressures do not change after startup in Vertiv Air Conditioner?
If the suction and exhaust pressures of your Vertiv Air Conditioner do not change after startup, it indicates that either the compressor is reversed or the internal air tightness of the compressor has failed. If the compressor is reversed, exchange any two L lines of the compressor. If the internal air tightness of the compressor has failed and cannot be restored, replace the compressor.
