Replacing the oven bezel
Be careful! The oven and/or bezel may be hot
enough to cause burns. If it is hot, wear gloves
to protect your hands.
The bezel consists of a plastic cover over a metal plate. It is held
by two screws that are reached through holes in the top of the
bezel.
1 Unscrew the two mounting screws.
Lift the bezel and metal plate off the GC.
When reinstalling, note that the lip on the bezel extends forward
over the top of the oven door. Be very certain that the metal plate
is between the plastic part and the top of the GC.
Replacing the inlet cooling fan
1 Cool down the oven and all heated zones to below 70 °C to
avoid the creation of active sites.
Turn off the GC main power switch.
Components can be damaged by static electricity:
be sure to wear an ESD strap grounded to the GC
chassis while performing this procedure.
