Our garage refrigerator (Kenmore with the freezer on the bottom) started not cooling in late July. The lights kept working & the freezer kept working, but the top part (the refrigerator section) stopped cooling and the temp adjustment buttons stopped working for the refrigerator section too. We unplugged it for 24 hours & when we plugged it back in, it started working just fine again... until about 2 weeks later when it happened again. This time while it was unplugged, we cleaned & vacuumed under it and behind it really well and when we plugged it back in we made sure it was pulled out a ways from the wall. Again, it fixed the issue and worked fine for maybe another week or so, but then it happened again! So repeated the process and it did the same thing again yesterday! 😩 We have had this (bought it used) refrigerator for about 1.5 years and it has always worked perfectly up until the end of July. Any idea what could be causing this problem???
My guess is it is not defrosting properly or a fan has failed. I go with not defrosting because of the 2 week cycle a failed fan it would probably not cool well at all. If not defrosting it takes time for the frost to build to the point of limiting the air flow. The display not properly functioning may point to some type of control board failure. It may be repairable and if you search online with the model number you will probably find the correct board for your model. Some of the sites that sponsor repair parts can be quite useful I have fixed stoves and dryers many times with parts from these sites.
