Not a fix but a recommended tool for the fridge.
An inexpensive wireless remote indoor outdoor thermometer.
I was having concerns and added this to the fridge. Doesn’t make it cool but allows remote monitoring, worked from our driveway into house during pre trip prep and then into TV for monitoring while towing.
