Remove the old door gasket. Clean the gasket channel
in the door and the chamber face. The door gasket has
a slight taper. The wider side is inserted into the door
first. Gasket Installation Tip #1 - Lubricate gasket with
soapy water before inserting into gasket channel.
Gasket Installation Tip #2 - For easy install of the new
gasket, use the “North-South-East-West” method (i.e.
begin installing the gasket at the top of the door, then
install the bottom, then the right side, then the left side,
and then everything in between making sure that the
gasket fits flush without bumps or gaps).
