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.
