Controller fixed it all. I had one snag, though. Having the freezer on and with the issue, it froze over the lower vent. I was thinking about tearing it open to try and get to and defrost the vent. I thought better, though. The directions said to wait 24 hrs to let the frig adjust. I figured that it would probably cycle into a defrost and fix the venting prob. It did.
Frig was set on 5 and was 32 degrees when I woke up. So I turned it down to 4.
