Refrigerator Maintenance
Gas flame appearance:
While in GAS operation, examine the appearance of the gas flame:
-Turn the temperature switch to the COLDEST position.
-Open the lower intake vent.
CAUTION: The burner box cover can be hot. Wear 
gloves to avoid burns.
Remove and clean the burner orifice:
Your dealer or Norcold authorized service center must do this procedure.
Remove and clean the burner orifice (See Art00956):
-Close the valve at the propane gas tank(s).
-Push the selector switch to the OFF position to shut down the refrigerator.
CAUTION: The burner box cover can be hot. Wear gloves to avoid burns.
-Open the lower intake vent.
-Remove the drip cup by removing the screw.
-Remove the burner box cover by removing the screw.
WARNING: To avoid possible propane gas leaks, always use two wrenches to loosen and tighten the gas supply line connections.
-Remove the flare nut from the orifice assembly [1] (See Art00956).
-Remove the burner [2] from the orifice assembly.
WARNING: Do not try to remove the orifice [3] from the orifice adapter [4] when cleaning. Removal will damage the orifice and seal of the orifice and can cause a propane gas leak. Leaking propane gas can ignite or explode which can result in dangerous personal injury or death. Do not clean the orifice with a pin or other objects.
