8.3 Air Leaks
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 in that place is not sealing
properly. This should be done on all four sides of the door
in several places. If a gasket is not sealing properly, lift
up inside of door gasket and insert 1/4” ball of berglass
insulation at all four corners on both doors. This is espe-
cially important to the top corners. Next warm the gasket
material with a hair dryer. 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
recheck 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 ush 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 insufcient cooling as well as
rapid formation of frost.
8.4 Interior Liner Seal To Frame
There is a seal that is applied to the liner in the area
where the metal frame makes contact with the interior
liner. If this seal is incomplete, cold air can migrate out to
the metal frame. If this happens, condensation could form
on the frame and could promote rapid formation of frost.
If you suspect an improper seal, apply a small bead of
silicone all the way around the perimeter where the frame
meets the interior liner. Next remove all screws securing
the refrigerator into the cabinet and slide the refrigerator
out approximately 2–4 inches. Clean the metal frame and
foil-backed insulation around the refrigerator. Apply a foil-
backed adhesive tape to the joint between outer frame
and foil-backed refrigerator insulation. Make sure the
refrigerator is dry and that the surface temperatures are
above 50° F. Use a clear silicon caulking compound and
seal the seam between the refrigerator’s plastic liner and
the metal frame. Apply the silicon in a continuous bead
around both the refrigerator freezer and food compart-
ments.

Another source for an air leaks could be the drain hose.
When units are installed, there is a check valve at the end
of the drain. At install the hose might be shortened and
the check valve must be moved to the end of drain hose.
Any time lack of performance or excessive frost is experi-
enced, look for the check valve at the end of hose.
APPLY FOIL-BACKED OR ALUMINUM
TAPE TO JOINT BETWEEN OUTER
FRAME AND FOIL-BACKED REFRIG-
ERATOR INSULATION. GO AROUND
THE COMPLETE FRAME.
