DUAL PRESSURE SWITCH CHECK

1.Remove the dual pressure switch connector and connect the high/low pressure side terminals located on the harness side as shown in the illustration. 2.Install a gauge manifold to the high-pressure side service valve of the refrigerant line (Refer to ). 3.When the high/low pressure sides of the dual pressure switch are at operation pressure (ON) the resistance should less than two ohms between the terminals. If open circuit, replace the switch.
