Main compartment not cold at

My "expert" was very knowledgeable and stepped me through diagnosis of what was wrong. It turned out to be an adaptive defroster assembly. I followed the instructions that other users had listed for the same part. Took me a little while (2 hours) to figure out how to get all the part disassembled with the right tools, but I am a girl (haha). Got the part replaced, had to wait about 18 hours to see if the main compartment got cold again, but wouldn't you know it, the next morning I had ice cold milk. Yeah!! With the $20 Fixya fee and the $75 part, I fixed the refrigerator for under $100. Very proud of myself. Just got laid off, maybe will become an appliance technician for my next career!!
