Way Valve - GE PFSS9PKY Technical Service Manual

3-Way Valve

The 3-way valve is composed of a magnetic coil
and a valve body and is located to the left of the
compresser in the machine compartment. It is
accessed from the back of the refrigerator. One
Phillips-head screw mounts the valve to the cabinet.
There are three copper tubes connected to the
3-way valve. One jumper tube connects from the
drier to the inlet on the valve. A freezer capillary
and a fresh food capillary connect to the other two
tubes on the valve.

Testing the 3-Way Valve
The valve returns to "home" at the end of every
freezer defrost cycle and whenever the refrigerator
is reconnected to power.
To test the valve, disconnect the refrigerator from
power for at least 10 seconds, place a fi nger on top
of the valve, and reconnect power.
The main control overdrives the valve to the "home"
position.
You should be able to feel the valve vibrate as the
coil moves the magnet to the home position .
If movement is present, the main board and valve
coil are operating correctly.
3-Way Valve Coil
The 3-way valve coil receives 12-VDC pulses from
the main board to change the position of the valve.
The pulses come too quickly to measure with a volt
meter.
The 3-way valve coil has a resistance value of
approximately 40 ohms that can be measured
between the coil pins.
