Sub-zero 642 refrigerator not cooling intermittently
eatkins posted a topic in DIY Appliance Repair Help
I have a 14 year old Sub-zero 642. The freezer works fine and holds temp. The refrigerator section will hold temp for days or weeks no problem and then all of a sudden go from 38 to 45. I thought that maybe it was because we overloaded the fridge but it happens whether full or less full and no matter the temperature in the house. I have no issue calling in a professional to fix it but I want to know a little about the issue so I am not taken advantage of. Any help is appreciated. I have looked at other forums and see others where the same thing has happened but haven't seen a consistent answer. Thanks in advance for any insights.
