If the temp reading in the upper part of the fridge is that high, it's likely the beer in the line is sitting higher in the warmer air, and causing the co2 to break out of the beer in the line. You need a small fan of some sort inside the unit to circulate air better. Ideally you have uniform temperatures from top to bottom.

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
