kenmore 596.69928011 refrigerator not cooling
My model has the freezer in the bottom. The fridge was unplugged for six months - located at a cottage. When restored power, the fridge seemed to be working, inside light and fan were working.
Fridge is about 6-7 years old and has never been a problem although water was collecting in the freezer floor which I assumed was due to plugged drain.
Took off back panel, fan is working blowing air and the compressor is warm.
Accessed the cooling coils from inside the freezer, taking off the interior panel. The coils are not cold or cool - room temperature.
I have no idea where to start. This is the second fridge that has stopped cooling in the past 8 years. Is this due to being unplugged in a uheated building over the winter?
Any help would be greatly appreciated-
