REPLACING THE DOOR GASKET
It is important to maintain the gasket in good condition. After a year or more of use, the door
gasket will compress and become hard, which may allow air to leak past it. You can test the
condition of the door gasket by closing and latching the door on a strip of paper. Test all around
the door. If the paper slips out easily anywhere, it is time to replace the gasket.
Use the correct replacement gasket that you can purchase from your retailer. The diameter and
density of the gasket is important to getting a good seal.
Place the door face-down on something soft like a cushion of rags or piece of carpet. Remove the
old gasket from the door by pulling and prying it out with an old screw driver. Then use the
screwdriver to scrape the old gasket adhesive from the door. Now run a 1/4” (6 mm) bead of high
temperature silicone in the door gasket groove. Starting from the middle of the hinge side, press
the gasket into the groove. Do not stretch the gasket as you place it. Leave the gasket about 1/2”
long when you cut it and press the end into the groove. Tuck any loose fibres under the gasket and
into the silicone. Close the door and do not use the stove for 24 hours.
5.1.4
REPLACING THE GLASS GASKET AND/OR THE GLASS
It is a good idea to replace the glass gasket when the door gasket is replaced. The gasket is flat,
adhesive-backed, woven fibreglass. Remove the glass retaining screws (A) and clips (B) then both
metal frames (C) that holds the glass (D) to the door frame (E). Lift out the glass and pull off the
old gasket. This is a good time to clean the glass thoroughly.
The gasket must be centred on the edge of the glass. To do this easily, peel back a section of the
paper covering the adhesive and place the gasket on a table with the adhesive side up. Stick the
end of the gasket to the middle of one edge, then press the edge of the glass down onto the
gasket, taking care that it is perfectly centred on the gasket. Peel off more of the backing and
rotate the glass and press the next section onto the gasket. Do not stretch the gasket as you place
it. Continue until you get to the start and trim the gasket to length. Now pinch the gasket to the
glass in a U shape, all around the glass. Reinstall the glass, being careful to centre the glass
carefully in the door. Do not over-tighten the screws. Note that the two main causes of broken
door glass are uneven placement in the door and over-tightening of retaining screws.
