Work from the corners to the centers of each side, top
and bottom. Carefully push the new gasket into the
groove at each corner, refer to Figure 10(A). Then,
push the gasket into the channel at the center of the top,
bottom and each side, Figure 10(B). Avoid stretching
the gasket.
Sub-divide remaining areas and push the gasket in at
those points, Figure 10(C).
Sub-divide once again and repeat pushing the gasket
in until all of the gasket is evenly seated in the groove,
Figure 10(D).
Use a soft cloth or paper towels to dry the gasket
before closing door on clean door frame.
RESTORING GASKET SEAL
Occasionally, a crimped or damaged gasket can cause
gaps in the seal (Figure 11), leading to frost formation
on the doors. Use this procedure to close gaps and end
frost formation on doors.
Locate Gaps
Normally, interior case lighting will provide enough
light to see gaps. In some cases, the only way to see
gaps is to provide a backlight as shown in Figure
12(A). Backlight the door mullion and look for places
the light shines between the door and gasket, Figure
12(B).
