• The oven should be connected directly to a
time delay fuse or circuit breaker through
flexible, armored, or nonmetallic sheathed,
copper cable. The flexible, armored cable
that extends from the appliance should be
connected directly to the junction box.

• Fuse both sides of the line.

• Locate the junction box to allow as much
slack as possible between the junction box
and the appliance so that the appliance can
be moved if servicing is ever necessary. Do
not cut the conduit.

• A U.L.-listed conduit connector must be pro­vided at the junction box.

• Wiring diagrams are located in Section 7 of
this Job Aid.

• A Tech Sheet is located below the top ac­cess cover on all models.

• Models rated from 7.3 to 9.6 kW at 240-volts,
(5.5 to 7.2 kW at 208-volts), require a sepa­rate 40-ampere circuit. Models rated at 7.2
kW and below at 240-volts, (5.4 kW and
below at 208-volts), require a separate 30­ampere circuit.

REMOVING & REINSTALLING THE OVEN DOOR

WARNING

Personal Injury Hazard

• Use both hands to remove oven doors.

• Do not use the handle or any portion of the
front frame or trim for lifting.

• Because of the weight and size of the
oven, two or more people are required to
move and safely install it.

Failure to properly grasp the oven doors or to
lift the oven properly could result in personal
injury or damage to the product.

CAUTION: Do not remove the shipping base
or the shipping feet at the front lower cor­ners of the oven. The shipping feet will
protect the lower oven trim until the oven is
inserted into the cabinet cutout.

2. Close the oven door as far as the two pins
will allow.

3. Grasp the sides of the door and lift the door
until it stops, then pull the hinge hangers
out of the slots.

Slot

Hinge Hanger

Shipping Foot

To remove the oven door:

1. Install a pin in the hole of each oven door
hinge hanger.

Door Pin

To reinstall the oven door:

1. Grasp the sides of the door and tilt it back
at a slight angle, then insert the hinge
hangers into the hinge slots as far as they
will go.

2. Rotate the top of the door towards the
oven so the hinge hangers fit onto the
support pins.

3. Close the oven door as far as the pins will
allow, and make sure that the hinge hang­ers are fully seated on the support pins. If
they are not seated properly, the door will
not close tightly and may be off-center. To
seat the hinge hangers, open the door
slightly, and push in on the bottom until the
hangers are fully seated.

4. Open the oven door to its fully open posi­tion and remove the two hinge hanger
pins.

PRODUCT OPERATION

AIR FLOW

Intake air is drawn into the oven at two loca­tions: through the control panel vent, (over the
latch assembly and the inner chassis top), and
through the side mounting rails (over the oven
sides and around the back). Air also enters the
oven at the back through the openings on the
upper section of the rear cover. At this point,
the air from the sides and the top mix. The air
is then pulled through the blower, down the
back of the unit between the outer and inner
rear covers, and out the front of the unit via the
bottom vent trim.

Air from the blower is forced over the cavity
vent. The pressure differential causes air to be
drawn from the cavity, where the air exits
through a small opening on the left side of the
control panel vent.

Air passes through the oven door by a combi­nation of natural and forced convection. Air
enters the door through the bottom slots, and
passes between the outer glass, and the angled
inner glass. This air exits through the top slots
in the door via natural convection. Air also
enters the bottom of the door, and is drawn
between the two pieces of inner door glass,
where it exits through the top slots in the upper
part of the door. This air is then drawn into the
blower, and is forced down the back of the unit
between the inner and outer chassis covers,
and finally out the bottom vent.

The purpose of the convection fan is to circu­late hot air inside the oven cavity, not to evacu­ate the air. Thus, the air flow for the convection
models and the non-convection models, is the
same.

THE OVEN SHUTDOWN THERMAL FUSE

& CONTROL PANEL THERMAL FUSE

There are two thermal fuses on the oven. The
thermal fuses operate as follows:

• Upper & Lower Oven Shutdown Ther-
mal Fuse — These thermal fuses are
located on the rear of the oven at the in­dicated locations. Each oven shutdown
thermal fuse opens L2 to the oven if the
temperature at the rear panel exceeds
160˚C/320˚F. The two fuses are one­time, non-resettable safety devices.

Upper Oven
Shutdown
Thermal Fuse

• Control Panel Thermal Fuse — Pro­tects the control panel area if the tem­perature exceeds 101˚C/214˚F. If the
fuse opens, it shuts down the entire unit
(no clock, etc.). One end of the thermal
fuse is connected to the control panel
at lug P7-1, and the other end is con­nected to the main wire harness. The
thermal fuse is a one-time, non­resettable fuse.
