RV Refrigerator Facts

We just finishing up the CrossRoads RV Rally in Shipshewana, Indiana, we had a great time giving educational seminars and just hRV Refrigeratoranging out with a great group of folks. 

As I reflect on all the questions that we were asked during our seminars – the Absorption RV Refrigerator is still the number one topic of all.  So, I thought I would provide more information on how to help this appliance work more efficiently with providing some great facts that you may not be aware of.

  • ·         Compressor vs. Absorption type refrigerators – there is a big different. The compressor (residential-type) is an electric motor with a refrigerant pump, whereas, absorption (RV) is done through chemicals and heat.

 

  • ·         Recovery time is vastly different from our residential units. For every minute the door is left open – it will take one hour to recover the cold air lost.

 

  • ·         RV refrigerators cool better when there are a fair amount of items being stored. However, over packing is a bad thing – temps will go up because of lack of airflow. Try to keep your refrigerator stocked well without over packing.

 

  • ·         For cooling properly these 3 things are needed:  Is it level? Is there proper ventilation? Do you have a heat source ( i.e. propane or electric)?

 

  • ·         It is not critical to have the refrigerator level while traveling. The rolling and pitching movement of the RV helps the refrigerator operate efficiently.

 

  • ·         To check for proper temperature, place a cup of water with a thermometer inside the cup. Wait 2 to 3 hours to check if the unit is already cooled down. If hot (unplugged), turn on and wait to check after 8 to 24 hours.

 

  • ·         Most refrigerators will have at least one auxiliary fan on the back side, check to make sure it is working properly.  If more air flow is needed – add an additional fan(s).

 

  • ·         If the odor of ammonia is present with a yellow film coating on the back side of the refrigerator, the cooling coil seal is broken.  This means the coils will need to be replaced.

 

  • ·         8 cubic foot and larger units should be at least 43 degrees F. or less at 110 degrees F.

 

  • ·         Proper temperature for the freezer is 0 degrees F. and inside the main cooling box is 37 – 42 degrees F.

 

  • ·         Place ice cream at the coldest part of the freezer which is the lower left side.  

I do hope you now have a better understanding of the Absorption RV Refrigerator.  Happy RVing!
