This is not quite a beer related as I would like it to be but it is affecting my beer fridge so I think it fits in this category.
I'm having trouble with my chest freezer I use for actually freezing things. In the mean time I have UN-converted the other chest freezer that held my beer to an actual freezer until I get the other fixed.
My issue is this. After the freezer runs for a day or two it gets stuck around 15-20F. If I turn it off and let it set for an hour or so and turn it back on it cools right back down to -5 for the next day or two. Then it does the same thing and gets stuck at 15-20F. This is not good for the food in there so I switched it out.
I have noticed, by using an IR thermometer, that when it's stuck in this phase the back wall of the freezer (on the inside) is quite warm. It's in the 30's. The front wall is ice cold in the -10to -15F range. During this time the freezer is running non-stop and it seems to be fighting itself. When the freezer is working properly both walls are very cold.
2 days ago I put my love controller on it and set it at -5 and it's staying just fine. I'm wondering if the thermostat might be bad and after it runs for awhile it stops working. I don't know much about refrigeration systems and you guys are the smartest guys I know
so I thought I'd throw it out there.
The freezer is a GE and it's 10 years old.
