B:Insufficient Refrigerating Capacity. Check:
1.The door is sealed properly and the refrigerator is not positioned close to heat sources.
2.Ice build up in and on freezer compartment. 1/8” maximum. Defrost Freezer by turning power off and let ice melt. Do not chip ice off freezer compartment because freezer plate can be damaged.
3.The refrigerator is sufficiently ventilated.
4.Dust has not blocked the condenser ventilation sources.
5.The Condenser Cooling Fan rotates freely.
6.The compressor and fan are operating properly. The compressor is very quiet during operation so it may be difficult to ascertain if it is running. A metal tube or a screw driver, position on the compressor and your ear, may help you hear the compressor motor when energized. If fan is running but the compressor kicks on and off, or the compressor is not running, change the Danfoss module (see Section A #12). If problem persists, it may indicate the compressor is bad or a refrigerant leak.
7.The inside temperature needs to be around 34F to 40F. If the temperature starts in this range but increases over time, put the refrigerator on a test bench, start it, let it run for an hour and check the Cap Tube/ Strainer Assembly located in the back of the unit. Look for condensation and/or ice accumulations as illustrated in the following pictures:
Ice accumulation around the cap tube usually indicates blockage.
Water condensation around strainer usually indicates moisture in the system.
If condensate or ice accumulates in these areas, replace unit.
