Possible causes

Faulty high pressure sensor Connection of low pressure sensor in mistake for high pressure sensor Faulty outdoor unit PC board Faulty connection of high pressure sensor NO High pressure sensor Red +5V 1 Make measurement of voltage of the pressure sensor. 2 See “Pressure sensor: Pressure vs. Voltage Characteristics Table” on ‘6 - 45. Pressure Sensor Characteristics’. Make measurement of DC voltage between these wires. Is the PC board detection pressure normal? Make a comparison between data on pressure checked by the Service Checker and the voltage characteristics. (See 2) Are the characteristics of the high pressure sensor normal? Mount a pressure gauge on the high pressure service port. Are the characteristics of the high pressure sensor normal? (Make a comparison between voltage characteristics (See 1) and gauge pressure.)
