REMOVING THE AIR SWITCHES

WARNING
Turn off the electrical power circuit to the
oven at the main junction box before ser-
vicing this unit.
CAUTION
When you work on the oven, be careful
when handling the sheet metal parts. There
are sharp edges present and you can cut
yourself if you are not careful.
NOTE: The air flow to the air switch in the
lower oven base compartment of all 27" S-Se-
ries ovens has been improved with the addi-
tion of an air diverter (#16-10-101). This im-
provement has been made to all 27" and 30"
ovens built in l998. The new air diverter is lo-
cated on the right side of the lower oven base
compartment (see illustration below). If you
encounter a 27" oven that was built in 1997
with no oven heat, due to the air switch not
closing, order and install the new diverter. You
will not see any error code messages in con-
trol display window if these problems occur.
Refer to illustration on Page 96 for the follow-
ing steps.
1. Turn off the electrical power to the oven.
2. Open the lower oven door. The bottom
trim mounting screws (see Inset 1, Page
96) are visible at each side of the oven
door, below the left and right hinges.
3. Remove the two screws from the bottom
trim, pull it forward, and remove it.
4. Remove the two front switches from the
air switch bracket and flange, and pull the
air switch bracket assembly forward so
you can access the switches (see Inset 2,
Page 96).
5. To remove an air switch from the bracket,
remove the two screws from the switch
body, and disconnect the wires from the
terminals (see Inset 3, Page 96).
6. Install the new air switch in the mount-
ing bracket.
7. If you intend to install the air switch
diverter, do so at this time. Make sure that
the spacing between the air switch paddle
and the end of the diverter is as shown
below.
8. Reassemble the oven.
