About 6 years ago it started freezing-up the condenser/radiator/coils in the freezer section which also regulate the fridge section and caused the fridge to become too warm. I used a heat gun on the back wall of the freezer to melt the frozen condenser behind it, and then a turkey baster to suck the water out of the collection pan at the back bottom. Had to do that about once or twice a year.

I replaced the thermostat a couple months ago and siliconed over the wire nuts and everything as per installation tutorials. A couple weeks ago it froze over again, so I defrosted it again and then it sort of happened again right after. So I set the freezer section to only 1 out of 7, and now it seems ok but might happen again it seems. Basically the freezer is still very cold on "1" because the coils I think are slightly frozen-over and keeping the coldness in the freezer. I have the fridge set to 4 of 7 and seems to be cold enough - I think we previously had the fridge at only 1 in order to help this problem but 4 seems to be doing ok for now
