Figure 27 Removing the glass lens

Panel Service Assembly section.
2. Using pliers, gently pinch the top of each spacer closed, then

align with the four spacers, and firmly push the board
downward until all four corners snap securely in place.

6.5 Cavity Lights
Each 30” oven cavity uses one incandescent 40W appliance bulb with
a standard Edison base. Each 27” oven cavity uses two 25W
incandescent bulbs (25WPRE14), with a European base.
Replacement bulbs may be purchased locally.
Figure 26 Left: 25W bulbs used in 27” ovens | Right: 40W bulb used in 30” ovens.
On double ovens, lights are either on or off in both cavities; it is not
possible to operate cavity lights independently.
The cavity light(s) can be turned on in two ways: by pressing Oven
Light or opening the oven door. If Oven Light had not been pressed to
turn light(s) on prior to opening the oven door, the light(s) will turn off
when the door is closed. If Oven Light had been pressed to turn
light(s) on prior to opening the oven door, the light(s) will remain on
after the door is closed.
In other words, the Oven Light switch overrides the door.
6.5.1 Replacing the Lamp
1. Unscrew glass lens cover by turning it counter-clockwise.
Sometimes, after running a self-clean cycle at high heat, it may become
difficult to remove the glass lens. If it cannot be done by hand, an
adjustable strap-wrench may be used.
Turn off power to the oven at the fuse or breaker box–light socket
is live with door open.
Be sure oven and lights are cool to the touch.
Handle glass lenses and glass bulbs carefully.
