Sub Zero 690/F Fridge is not cooling

26 December 2013 - 02:35 AM

I would like to start by saying that I have zero experience in repairing refrigerators. I just recently found a repair video for a SubZero, which helped me at least get an idea of what to look for and that's why I'm here. I'm fairly handy and can 'DIY' almost anything with enough knowledge and proper tools, so I would like to repair this one myself.


Our SubZero Fridge section has not been cooling properly for years. We have tried cleaning the condenser, but it hasn't made a noticeable difference. Just today, it completely stopped cooling and made the temperature go up to over 70 degrees (control panel readout). Some other little issues: the fridge door sticks out by about a quarter of an inch, the door gasket has a cut at the bottom, and the light switch is not working properly.


The freezer is working fine.


With all this trouble, I started reading similar threads and articles and realized that I may have missed the tell tale signs of a bad evaporator. If memory serves me correctly, I had a lot of ice buildup on the back panel/evaporator cover and standing water in the fridge.


I took the back panel off and here is what I saw.







There was also a lot of hissing, coming from the little pipe (cap tube?). The evaporator is warm to the touch.


Now do you think the evaporator is bad? And if the refrigerant has escaped, would my compressor still be okay?


Also, I read that there is diagnostic mode. How do I put the system into that mode to get all the trouble codes?
