On heat-pump models, the refrigerant ow
direction is controlled by the reversing valve
assembly. In the cooling mode, the main board
supplies line voltage to the solenoid coil, which
causes the valve to switch ow direction. With no
voltage applied to the solenoid coil, the valve will
be in the heating mode.
The solenoid coil attaches to the valve body with
a 5/16-in. hex-head bolt. The 230/208-volt coil
has pink wires and measures approximately 1.5k
ohms.
