NOTICE
This service data sheet is intended for
use by
persons
having
electrical and mechanical training and
a
level of .
knowledge
of these
subjects generally
considered acceptable in
the appliance

SAFE SERVICING
PRACTICES
To avoid
the
possibility
of
personal injury
and/or
property
damage, it is important that safe servicing practices
be
observed.
The
following
are examples, but without limitation, of such
practices.
1. Do not attempt a product repair if you have any doubts
as to
your
ability to complete it
in
a safe and
satisfactory manner.
2. Before
servicing
or
moving
an appliance, remove
power
cord from electric
outlet,
trip circuit breaker
to
Off,
or remove fuse and turn off gas supply.
3. Never interfere
with
the
proper
installation of
any
safety
device.
4. USE
ONLY
REPLACEMENT PARTS CATALOGED FOR THIS
APPLIANCE. SUBSTITUTIONS
MAY DEFEAT COMPLIANCE
WITH SAFETY STANDARDS SET FOR HOME
APPLIANCES.
5. GROUNDING: The standard color coding
for
safety ground
wires is
GREEN OR
GREEN
WITH YELLOW
STRIPES.
Ground leads are not to
be
used as current carrying
conductors.
IT
IS
EXTREMELY IMPORTANT THAT THE
SERVICE TECHNICIAN REESTABLISH ALL SAFETY
GROUNDS PRIOR TO COMPLETION OF
SERVICE. FAILURE
TO
DO SO
WILL CREATE A POTENTIAL HAZARD.
6. Prior to returning the product to service, ensure that:
•
All
electric
connections
are
correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high -temperature components,
and moving parts.
• All non -insulated electrical terminals, connectors,
heaters, etc. are adequately spaced away
from all
metal parts and panels.
• All
safety grounds
(both internal and external)
are correctly
and
securely
reassembled.
• All panels are
properly
and
securely
reassembled.

Note:
Depending on
model,
the size and
shape
of touch
pads may vary
(for
example
round instead
of
elliptical).
NORMAL
BAKE
During
a
normal
bake
mode,
the
control
preheats the oven with
the bake
element.
When
the
desired
temperature
is reached, the control adds
top heat by cycling
the
broil
element
on
for 6
to 9 seconds per minute.
The
bake
element
is
on for
the
remaining
time of
the minute. Both
elements
use
full
power when
they
are
on
but they
are never on
at the same time.
CLEAN
During
a
cleaning
process, the oven
uses the bake
element.
When
this
mode is called, the door
locks right after start
button is
pushed.
FIRST RISE
It is normal
to see
a
temperature
overshoot
in
the
first rise of all
modes
when
you monitor

DOOR LOCK
MECHANISM
The
appliance is
equipped
with an electronic oven control and has
an
auto
locking door latch feature.
When
the self clean cycle is
programmed,
the door is locked by a
motor
operated
latch system. The
interior
of
oven
does'nt
need to heat up
to 500°F/260°C
before the door locks. However, until the temperature
inside
oven
reaches
500°F/260°C, the
self -clean program
can be
canceled and
door will unlock immediately.
After oven
reaches
temperatures
over
500°F/260°C, the door
will
not unlock until temperature
drops below 500°F/260°C.

When the
temperature
at
the
preheat
thermostat
reaches 130°F the thermostat
opens. This forces
the current to flow
through
the
parallel circuit
which
contains the diode. The diode allows only half power (every
other
pulse
of
electric-
ity or
pulsating DC)
to
flow through
the
element,
resulting in lower
heat
output by the element. The infinite heat
control
switch will cycle
as
necessary
to
maintain
the
temperature
in
the
drawer
as indicated by the control
switch
setting.
If the
control
is
placed on
a
lower setting,
it is possible
for
the temperature in the
drawer to
drop
enough to
allow the

to close
again which will allow
