What was the air temp in the fridge at 73F room temp? The cooling
fins will get really cold but that's where the good news ends. It
seems to me anyway that the Dometic really flunks out when the air
temps get up past 80F. At 90F my fridge is at 50F---a 40F degree
difference --- not nearly enough. What's your air temp inside to
outside differential?
