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 repair trade
The manufacturer cannot be responsible, nor assume
any liability for injury or damage of any kind arising
from the use of this data sheet
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. Before servicing or moving an appliance remove power
cord from electrical outlet, trip circuit breaker to FF,
or remove fuse.
2. Never interfere with the proper installation of any safety
device.
3. GR UNDING: 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 safety hazard
4. 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 uninsulated 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.

Surface Elements (Infinite) Switch
The surface elements and controls provide an infinite choice of heat
settings for cooking. Controls are safety type and must be pushed in
before turning. All surface controls are marked on the control panel for
their respective heating element. Power is supplied to the surface
elements through the infinite switch contacts L1-H1 and L2-H2.
Continuity tests can be performed on the infinite switch contacts. All
tests should be performed with power to the range disconnected, and
wiring removed from the switch. Set an ohmmeter on R X 1K scale
and check the contacts in the chart below (Fig. 1). The location of the
switch terminals is shown in Fig. 2.

If the infinite switch contacts are good, and the element does not heat,
check for voltage at the element receptacle. If no voltage is indicated,
check for broken wiring or loose connections. If voltage is indicated,
the problem is in the heating element.

N TE: During actual surface element operation, contacts L2-H2 will
cycle to maintain the correct heat setting. Contacts L1-P provide
power to the surface element indicator light.
Bake Element
If the bake element does not heat up, check for line voltage across
element terminals. Approximately 240 VAC should be indicated
across terminals. If no voltage is indicated across terminals, check
for broken wire between thermostat and element. Check thermostat.
If voltage is present at the element, check element for continuity
using procedures below.
1.Shut off power to range.
2.Remove wire leads from element terminals.
3.Set ohmmeter to R X 10 scale and attach meter leads to element.
A low HMS reading (continuity) should be indicated. If infinite
HMS (open) is indicated, element must be replaced.
Broil Element
If the broil element does not heat up, check for line voltage at
element terminals. Approximately 240 VAC should be indicated at
the element. If no voltage is indicated across terminals, check for
broken wire between thermostat and element. Check thermostat. If
voltage is present at the element, check element for continuity using
procedures below.
1.Shut off power to range.
2.Remove wire leads from element terminals.
3.Set ohmmeter to R X 10 scale and attach meter leads to element.
A low HMS reading (continuity) should be indicated. If infinite
HMS (open) is indicated, element must be replaced.
Thermostat Selector Switch
The temperature control is a combination thermostat and selector
switch assembly. The temperature control is performed by cycling
contacts in the thermostat.
The selection of bake or broil operation is done at the control dial.
The contacts C-BA are closed when a bake temperature is selected.
The contacts C-BR are closed when the broil function is chosen.
Oven Indicator Light
The oven indicator light operates any time the thermostat selector
switch is placed in operation. It will cycle with the operation of the
cycling contacts in the thermostat (glows with contacts closed). It is
a 240 VAC indicator light.

Indicator Light
If the elements heat up but the indicator light does not glow,
check for voltage at the indicator terminals. 240 VAC should
be present at the indicator terminals. If voltage is present at
the indicator terminals, replace the indicator light. If no
voltage is present at the
indicator terminals, check for loose connections, broken
wiring, or open L1-P contact in the infinite switch.
Surface Elements
If the heating element does not heat up, check for line
voltage at receptacle. Approximately 240 VAC should be
indicated at the
element receptacle with the infinite switch in the HI position.
If no voltage is indicated at receptacle, check for loose
connections, broken wiring, or a defective infinite switch. If
voltage is present at the receptacle terminals, check element
for continuity using procedures below.
1.Shut off power to range.
2.Remove element from receptacle.
3.Set ohmmeter to R X 10 scale and attach meter leads to
element. A low HMS reading (continuity) should be indi-
cated, and this reading may vary slightly on each element
tested. If infinite HMS (open) is indicated, element must be
replaced (see Fig. 3).
