Domestic refrigerator 4 door replaced June 2015.
Turned the unit on for an upcoming weekend trip.
Freezer is cooling well, but the refrigerator is not.
Also, the part of the door that separates/seals the area is actually guite warm.
Started on AC, but now trying LP to see if that makes a difference.
Ideas? Thoughts?
