Refrigerators
Check the gasket on the doors to be sure of a positive
air seal. A simple method to check gaskets is to close
the door on a dollar bill, then pull the dollar bill out. If no
resistance is felt, the gasket is not sealing properly. This
should be done on all four sides of the door. If a gasket
is not sealing properly, first warm the gasket material
with a hair dryer.
DO NOT OVERHEAT
AS YOU CAN MELT THE MATERIAL.
Then close the door and the magnetic strip should pull
the gasket to the metal frame. Leave door closed until
the material has cooled. Then re-check for a positive
seal. If a positive seal cannot be achieved, replace the
door gasket. Also check that the cooling unit is installed
properly. The cooling unit’s foam block, the portion that
surrounds the evaporator coils, must be flush to the
cabinet at the back of the refrigerator and have a
positive seal. If the cooling unit is not installed properly,
remove and install properly.
NOTE: Air leaks will cause insufficient cooling as well as
rapid formation of frost.
8.4 DOOR POSITION
The door position can be checked by observing any
misalignment of the door in relation to the frame.
To correct an
alignment of the door, loosen the hinge screws slightly,
and re-orient the door in the proper position. Hold the
door in its new position and carefully retighten the hinge
screws.
If the door needs more adjustment than is available
through the hinge adjustment, the base can be reposi-
tioned to re-orient the door. Turn the refrigerator on its
side to gain access to the two front base screws. Loosen
both screws slightly. Reposition the base until the door is
re-oriented. Re-tighten the base screws while holding
the base in its new position.
NOTE: Improper position of the lower door can cause
the interior light to stay on when door is closed.
8.5 AMBIENT TEMPERATURE
This is the temperature surrounding the recreational
vehicle, as well as the temperature of air at the back of
the refrigerator. As the ambient temperature increases,
the air temperature in the area of the cooling unit
increases. Improper venting at this point, will cause the
cooling unit to have reduced efficiency.
