Cold weather refrigerater

This may answer someones questions about your fridge.
Had a friend of mine take his motor home out as to load it for a trip. He noticed that the fridge would not cool. He tried gas and the electric. Nothing. He called a tech and the tech told him that the circuit board was out of it. He went to Campers World and purchased a new board. Installed it and it still would not work. I didn't know it nor did he, the fridge will not work below 20 degrees. He heated the motor home up and everything worked fine. If you look in the outside compartment at the fridge you will see a receptacle. that was put there so that you can plug in a 100 watt light bulb in the compartment in cold weather to make the fridge run below 20 degrees

  • I didn't know a RV refrigerator would not work under a certain temperature.
    But, to me, if it's too cold for the refrigerator to work, it's too cold to go camping. :)
  • Some models have a "LAT" switch ....Low Ambient Temperature ---below 50*F ON to provide heat so fridge cooling cycles run longer thereby keeping cooling solution in motion longer.


    Those models w/o an 'LAT' can benefit from a 'heat' source in outside compartment for same reasons.
