Testing
To test whether the 3-way valve is receiving a
signal from the power control board:
1. Turn the power OFF at the main switch for at
least 10 seconds.
2. Place a fi nger on top of the valve.
Caution: Be careful of the condenser fan and any
exposed wires.
3. Turn the main switch back on. You should feel
movement, and you may hear the 3-way valve
move to the home position.
4. If movement is detected, the power control
board and valve coil should be OK.
Replacement
When replacing the 3-way valve, note the red
sleeve on the valve tube. This tube connects to
the freezer capillary. The corresponding freezer
capillary has red paint above the braze joint.
The 3-way valve is extremely sensitive to heat.
When brazing, thoroughly cover the valve base
with heat absorbing paste (part # WR5X8927).
Make certain to direct the fl ame away from the
valve body.
