Thermal Line Break Thermal Cutout (TCO)
The thermal line break TCO is wired in series with
the common side of all the elements and is used to
protect against element runaway. The line break
opens at 302°F and resets at 272°F. If the TCO
opens, check for a constantly closed double line
break relay and one or more element relays.
Single Wall Oven
The TCO is underneath a cover behind the control
compartment. To access this cover, remove the
oven from the installation. (See
Oven Removal
.) The
cover is held in place by three ¼-in. hex-head
screws and a single tab. The TCO is held in place by
two ¼-in. hex-head screws.
Double Wall Oven
The TCO is located in the lower control compartment
between the top and bottom oven. (See
Lower Oven
Control Compartment Access
.)
The TCO is held in place

Oven Light Assemblies
Each oven is equipped with two halogen light
assemblies located on the side walls of the oven.
The oven door switch monitors the position of the
oven door and provides this information to the
logic board. The logic board operates the light relay
located on the relay board. The lights come on when
the door is opened or when the oven is in a cooking
cycle. The oven lights do not come on during self-
cleaning or if the Sabbath Feature is set.
Each light assembly consists of a removable light
cover with two locking clips, a light housing with
three light bulb sockets and three halogen light
bulbs.
To remove the oven light assemblies:
Remove the oven from the installation, then
remove the side access panels. (See
Oven
Removal
.)
If removing the oven light housing from a single
wall oven (or the upper oven on a double wall
oven) remove the 5 Phillips-head screws and
the top cover. If removing the oven light housing
from the lower oven, access the lower oven
control compartment. (See
Lower Oven Control
Compartment Access.
)
Disconnect the oven light wire harness.
Carefully lift the insulation from the outside of
the oven.
Remove the tape that attaches the oven light
wiring to the meat probe outlet wiring.
Pull light wiring through the wiring entry hole.
Remove the light cover. (See
To remove a light
bulb
,
on the next page
.)
Remove the two ¼-in. hex-head screws that
attach the light housing to the oven liner.
Pull the oven light housing from the oven liner.
Note:
Upon reassembly, ensure displaced insulation
around oven and components is returned to it's
original position.
