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).
