3-22 CAUTION : Sealed System Repair
Before making a sealed system repair : Start with the power cord unplugged from the outlet. Plug in the power cord and
between 6 and 12 seconds after it has been pugged in, unplug it from the power source. this will allow both sides of the 3
way valve to be opened to allow for proper evacuation.
3-23 Way Valve Service
Whole picture of refrigerator
R-Evaporator
F-Evaporator
■ The 3 way valve has plastic parts inside, so always wrap
it with a wet cloth before servicing when using a torch.
1) Always replace the 3 way valve if there is a leak at any
one of the 3 tubes coming from it.
2) Service in replacement of valve (valve failure) Perform
service in the same method as above.
Note : To service sealed system, follow the directions in “3-22”and “3-23”above.Then service is the same as a single
evaporator system.
