Compressor problems
I got a second opinion yesterday from someone a little more experienced with an older refrigerator. He was able to simulate my problem by turning the temperature in the freezer up to get the compressor to turn off. Unfortunately, when he turned the temperature back down the compressor and fan would not restart after an hour. He and his boss felt that the compressor was failing. Cost is about $1000 to fix, which I can see why when he explained all the work that had to be done. I told him I had to speak with my husband before I could commit to the repair.
After the repairman left, I did the same thing I did before, which was cool the compressor down with an extra fan, waited an hour or so and then plugged the fridge back in. It cooled off the interior and is working just fine, but I know I cannot keep a portable fan on it all the time, so I am not sure what to do now. I really want to fix it, but hubby is not a huge fan of vintage anything, so the chances of him forking over $1000 to get it fixed are slim to nil.
John, I bought the fridge without a back panel. I too have been wondering if that was part of the problem and trying to figure out where I could get one as it seems unsafe to not have one. I am not sure if the repairman did everything you suggested, but I hope so. Thank you so much for the great advice.
