Door Hinge Assemblies
The door hinge comes as a complete assembly.
For the hinges to operate properly , the hinge arms
must be perpendicular to the door liner and parallel
to each other with the door in the open position.
Door Hinge Replacement
1. Remove the door. Refer to Lift-Off Oven Door.
2. Remove 3 or 4 screws (depending on model)
from the bottom door frame.
3. Remove 2 screws from each side of the door,
and separate the door liner and the outer glass
assembly.
4. Remove 3 or 4 screws (depending on model)
from the door liner to remove each door hinge
assembly.
Note: When assembling, make sure the hinge
arms are parallel to each other and perpendicular
to the door liner. If not, the hinge may bind on the
receiving channel of the door.
Note: If the new hinge is not in the cocked and
locked position after installing, place the bottom of
the door against a firm surface and push the hinge
arm down to the cocked position. Pull the hinge
lock back against the door liner surface to lock the
hinge in this position.

Component Compartment Airflow
The component compartment contains a fan
located on the rear wall of the compartment. Fan
blades pull air in from the back of the unit, circulate
it in the compartment area to cool the components, and exhaust it through the louvers below the
control panel.
The fan turns ON when the START pad is depressed after selecting a cook mode. It turns OFF
when the CLEAR/OFF pad is depressed or when
the COOK TIME has ended.

Electronic Range Control (ERC)
Caution: Components are electronically hot on
ERC when voltage is connected to range
Note: Temperature/Mode Selection is necessary
for operation of relay contacts.
Note: Voltage must be present across terminals
L1 to N for ERC to operate.
There are 7 basic ERC configurations (see illus-
trations). The ERC contains the bake and broil
relays, convection relay (some models), control
transformer, lock motor relay (some models),
sensor, and lock motor connector (some models),
along with a series of 1/4-in. terminals for connecting power to the control and heating units.

Key Panel Test
The key panel (control panel) and Electronic
Range Control (ERC) are separate components
and must be tested individually .
The key panel is connected to the ERC by a ribbon
connector . The ERC will sound a tone when any of
the pads are depressed except for the +/- pads or
number pads (unless another pad is pressed first).
To help isolate a problem to either the ERC or key
panel, depress each pad on the key panel followed
by the Clear / Off pad and observe the following:
• Bake, Broil, Clean, Timer, Clock, Convection,
Warm, and Cook T ime Pads - Audible tone plus
display showing mode of operation selected.
• Clear / Off - Audible tone and display shows
time of day .
• Oven Light - Oven light turns on - Audible tone
and relay click.
• Temp, Hour, Min, +/- or Number Pads - No
audible tone. Can only be used after another
function pad has been selected.
Ribbon Cable Connections
If some of the pads work and some don’t, the
problem is probably with the key panel. To verify
that the key panel is the problem for Membrane
Control Models, check the connector for proper
insertion of the ribbon cable and perform the
Ohmeter Test.
Note: See special instructions for Glass Touch
Models Only , page 25.

Ohmmeter T est
123456789
1011121314
Note: The Ohmmeter Test can be performed on
Membrane Control Models ONLY. Glass Touch
Models should read infinitely high resistance
between ALL pins.
If some of the pads work and some don’t, the
problem is probably the key panel. To verify that
the key panel is the problem, perform the Ohmmeter Test. If the ohmmeter reads infinite ohms when
depressing the pad, or shows less than 1 MEG
OHM without depressing the pad, the key panel is
bad. The ohmmeter should read under 300 Ω
when pressing a pad.

Glass Touch Models ONL Y
Touch Control
Check the touch control panel for delamination to
make sure the touch board is not separating from
the glass. Next, check to make sure the resis-tance is infinitely high between ALL pins. Any
impedance implies a faulty touch control.
Attention: The new glass touch models maintain
a constant exchange of information between the
touch control and the main board through a ribbon
cable. These signals have an upper and lower
value limit for the ERC to interpret them correctly .
Any interruption to this connection will break the
continuity , and possibly push the parameters
outside the limits. This will issue an F0 fault code,
and cause the controls to not function.
When any service is performed that requires
moving, or removing, the touch control or
main board, the glass touch parameters must
be set.
Setting Touch Control Parameters
Note: After installing the control, the glass touch
parameters must be set. If they are not set, the
control will not operate.
To set these parameters on a new part
installation:
5) If steps 2 through 4 do not occur as described,
repeat the process.
6) Check the control for operation, especially the
“Clear/Off” and/or “Cancel” keys.
Note: If for any reason the control panel is
opened, or if the new control still does not
operate as described above, complete the
following steps:
1) Press the “Bake” and “Broil” keys
simultaneously.
2) For digital keypads, press the “9” and “0” keys
simultaneously for 5 seconds.
For slew keypads, press the “Hour Down” and
“Minute Down” keys simultaneously for
5 seconds.
3) Wait approximately 20 seconds after the time
of day is displayed.
4) For digital keypads, press the “1” and “5” keys
simultaneously.
For slew keypads, press the “Temp Up” and
“Minute Up” keys simultaneously .
5) The control will briefly go blank,briefly display
all LED segments, briefly display “LOC REF,”
then display all segments for 30 seconds, and
finally display “LOC REF.”
1) Reassemble the control panel and return the
oven to its normal installation.
2) Reset circuit breaker to apply power to the
oven. The control will briefly display all LED
segments, briefly display “LOC REF,” then
display all segments again for 30 seconds, and
finally display “LOC REF” continuously . After
this sequence is completed, proceed to step 3.
3) For digital keypads, press the “6” and “8” keys
simultaneously.
For slew keypads, press the “Hour Down” and
“Minute Up” keys simultaneously .
4) The control will then display the time of day
and operate.

Motorized Door Lock
T op Oven
The motorized door lock assembly is located
above the oven. The assembly consists of a lock
motor cam and switch assembly, lock hook, heat
barrier , and mounting plate.
Access to this assembly, for single and upper
ovens, is behind the control panel. For lower
ovens, access is behind the trim cover between
the 2 ovens.
Motorized Door Lock Operation
The lock motor is energized when the control is
set for Clean and Clean Time selected. The relay
contact will close and complete the circuit that
supplies the voltage to the lock motor. (See table
for relay identification.)

Oven Thermal Switch
Note: Oven thermal switch is used only on the
27-in. wall oven models.
A self-resetting, disc-type thermal cutout switch is
mounted to the rear of the oven. The switch will
open L2 to the heating elements in the event of an
overtemperature condition. Single, lower oven, and
microwave/oven combination switch opens at
284 °F (140 °C) and closes at 254 °F (123 °C).

Clean operation.
Note: When door is either being locked or unlocked, both lock switches will be in the open
position.
Thermal
Cutout
Switch
Lock Thermal Switch
The thermal switches are located in the component compartment (see photo). The lock thermal
switch circuit is in the normally closed position.
There are two thermal limit switches. One is for
thermal protection during selfclean mode (located
in the yellow neutral wire of the door lock circuit). It
opens between 240 °F (116 °C) and 365 °F
(185 °C), and closes between 190 °F (88 °C) and
293 °F (145 °C), depending on model.
The other thermal switch is for sensing cooling fan
operation during non-selfclean modes only (located in unlock switch side of door lock motor
circuit). It opens between 176 °F (80 °C) and 212
°F (100 °C) and closes between 149 °F (65 °C)
and 185 °F (85 °C), depending on model.
If the thermal switch opens in any mode of operation, the control will go to -F9- failure code. When
this condition exists, check the fan operation (look
for obstructions) and inspect oven installation
(make sure grill areas are not blocked), oven
insulation, and lock circuit.
Note: Oven must be removed from installation for
access to the thermal cutout switch.
