I've had a 15 cu ft chest freezer converted into a keggerator for 3 years now.  Since day one it's been set at 36, with the cooling turning on at 40.  Just recently, I've noticed the keg diagonally opposite the temp probe has been freezing, first a dunkelweizen, then my soda water.  The probe hasnt moved in 3 years, the temp settings haven't changed, but that corner does seem to be icing up preferentially.  Any thoughts?

I've got small fans running constantly in all (3) my chest freezers, just to keep the temps even.

Makes a huge difference!

Maybe there's a problem with the coils?

And that's the one thing I didn't want to hear

I'm going to go with bad packing of the kegs, restricting airflow in that corner.  The corner icing indicates moisture build up, so add some dessicant and some fans to move the air around, or move the kegs so the air can flow easily between them, or both.
