How to Fix an RV Fridge That Is Not Cooling

Recreational Vehicles generally use gas absorption technology that can run using one or more permutations of 120 volts AC, like the current supplied at home; 12 volts DC, which is the current provided in most RVs; or Liquid Petroleum Gas, sometimes called propane. An RV refrigerator that's not cooling properly can often be fixed by following some maintenance procedures, and making sure that it's installed properly.

Instructions

    • 1

      Clean the burner jet if the fridge isn't cooling properly and the fridge is being operated with propane gas. Turn off any AC or DC power and turn off the manual gas shut-off valve. Remove the cover from the burner housing and disconnect the wire that leads from the electrode. Remove the burner mounting screw and take out the burner assembly. Remove the baffle and clean the flue with the brush.

      Replace the baffle and clean the burner tube with the brush. Blow out the burner with compressed air. Clean away any soot and scale and then soak the jet in the alcohol. Re-install everything and then turn on the gas. Check for leaks by coating all of the fittings with soapy water and looking for bubbles.

      Level the refrigerator if you continue to have problems with cooling. These devices have to be level. Use the RV's leveling system when parked.

      Verify that the fridge hasn't shifted during transit and that there is still a gap all the way around the fridge if problems persist. The technology used by RV refrigerators requires a gap between fridge walls, fridge top and cabinetry.
