The unit is not in a slide. I designed the fan to force the air through the cooling unit. I molded the fan into an extra fridge outside cover so it is actually forcing a LOT of air through there and out the top. I made this fan on bottom because the 2 fans at the top are not working and I don't have time to pull the fridge to replace/repair before a trip this week. I know just blowing air in the bottom is not like drawing it through from the top and that is why I am forcing the air through the compartment. I'll post a picture here in a bit to show you what I built.
I can't figure out was is wrong if that's not causing it. It has ran for 3 days with the temps holding at 35 and 36 degrees. All of a sudden last night the temperature went up to 42 degrees. The fridge had not been opened for 12 hours. The temp going up 6 degrees over about 5 or 6 hours doesn't seem right. I checked it this morning after turning the temp up to 9 and it has cooled back to 36 this morning.
