Refrigerant Circuit ProblemsSystem Condition 6 1. The low pressure gauge reading does not change. The pressure should rise when the compressor is not in operation. For normal operating pressures, refer to Table 1. 2. High pressure gauge reading is at the high end of the normal range. Note: Ambient temperature is above 21°C (70°F). 3. The temperature of the air flow from the evaporator is partially cool.Probable CauseThe...
