Heat the Gasket

Make sure the door is closed. Beginning at the top of the gap, use a heat gun or electric hair dryer (1500-1600 watt) to heat the gasket with a constant up and down motion.

IMPORTANT: If a gap runs the entire length of the door, heat the area 4 in. (100 mm) above and 8 in. (200 mm) below the top-most point where the gap starts and work in

12 in. (300 mm) increments.

If the gasket becomes shiny, remove heat immediately as this is an indication that the gasket is near the melting point.

If possible, direct the hot air onto the gasket and also through the gap between the gasket and mullion. This will help to heat both sides of the gasket. Refer to Figure 13(A) and (B).

As the gasket softens and becomes pliable, the magnet in the gasket should pull it across the gap. As the gap closes, move heat down to create a zippering effect as shown in Figure14.

If the gasket is not pulled across the gap by the magnet, reach around the mullion (from the inside) and pull the gasket skirt toward the mullion.

Direct the hot air through the gap between the gasket and mullion.
