Hinges , may be performed by most users. However, all
other service procedures involve possible exposure to line
voltage. Only qualified service personnel should under-
take these procedures. The second section,

required for subsequent service sections and is refer-
enced by these later sections when required.

Replacing the Door Gasket
The Isotemp 800 Series ovens incorporate a durable,
fiberglass door gasket to minimize heat loss. Should the
gasket become defective or be damaged, it may be
replaced by following the procedures below.
1. Set the power switch to the off position and
open chamber door.
2. Remove the screws securing the stainless steel
inside door panel.
3. The gasket is attached to the inner door panel
by screws passing through the gasket lip and
the sandwich of the inner panel and door.
4. Remove the old gasket and position the new
gasket lip under the stainless steel inner panel.
Push the screws through the gasket and replace
the inner panel. Trim gasket length as neces-
sary.
