The refrigerator had been acting for like a month, it would get cold then for no reason it would just stop working. But the bottom always stayed colder then anything else, so I googled until I found a forum for doing it yourself

I first removed the panel in the bottom so I could see the fan and the Bimetal thermostat. Also removed back panel so I could see the tester wire and make sure I was going to be able to pull it though the small hole. Removed the old thermostat. Clipped new one on made sure I had reconnected all plugs correctly. Turned on refrigerator and waited about 30 minutes to see if fan kicked on and all was good replaced panels. This was totally great for me, I'm a woman and for me this was very exciting for me to be able to fix it myself without having to call in a repair man or just replace the refrigerator.
