Simple idea for improved refrigerator performance.
Most fridge problems occur due to poor installation.
A small piece of fire retardant insulation batt stuffed into the cavity above the fridge, via the rear external top vent, can improve the fridges insulation from heat, which in turn results in a better performing and operating refrigerator.
Optimal refrigeration setting on a Dometic 3 way fridge is at 4—5 on the temperature control.
We run an Waeco external thermometer on our fridge, to regulate the temperature and to ensure ice cold beer!
