Specifi cations of Refrigerant Valve Operation3-4.
Modes and operating conditions of refrigerant valve (3-way valve)1)
Valve is fully closed:1.
• This mode is used in compressor OFF status.
Only fine capillary is opened:2.
• During normal cooling operation
Only wide capillary is opened:3.
• During cooling operation under large load
Both capillaries are opened4.
• The refrigerator is set in this mode for only one minute after the power supply is turned ON. This mode is used for
vacuuming. During cooling operation, this mode is not used.
• Differentiation between fi ne capillary and wide capillary
- Fine capillary: Capillary tube A
- Wide capillary: Capillary tube B
- The fi ne capillary is identifi ed with a yellow mark.
Fault and status of refrigerant valve2)
• There is no method to give an instruction from the PWB and confi rm the valve position.
Refrigerant valve status Problem
1
Both capillaries are opened, and the valve does not operate.
No problem on cooling operation
No problem
2
Only the fi ne capillary is opened, and the valve does not operate.
Cooling performance deteriorates under large load.
Refrigerant shortage may occur, causing frost around
the evaporator inlet to increase.
3
Only the wide capillary is opened, and the valve does not operate.
No problem on cooling operation
No problem
4
Both capillaries are closed, and the valve does not operate.
