WAVE GUIDE COVER REPLACEMENT
The wave guide covers keep moisture and debris
out of the wave guides. If contamination gets into
the wave guides, the life of the magnetrons may be
shortened. Be careful to not allow debris to enter
the wave guides when replacing the covers.
To remove the wave guide covers, reference Figure
22 and follow the steps below:
1. Locate the fourteen (14) #8 sheet metal screws
securing the broken wave guide cover. If the
screw heads are dirty, it will be necessary to
clean the heads thoroughly.
C A U T I O N
: Do not strip the screw heads.
2. Remove the fourteen (14) #8 screws. The cover
should come loose with gentle pressure.

screws (Item 30). These screws secure the wave
guides to the oven floor. Only remove them if the
wave guide is also being serviced.
3. Remove the old wave guide cover and discard,
unless otherwise specified.
N O T E
: It may be necessary to gently pry the
wave guide covers to remove them from the
oven floor as they are sealed with
RTV.
