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 OFF, or remove fuse.
2. Never interfere with the proper installation of any safety
device.
3. 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 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 (Infi nite) Switch The surface elements and controls provide an infi nite 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 infi nite switch contacts L1-H1 and L2-H2. Continuity tests can be performed on the infi nite 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.
Fig. 1
If the infi nite 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.
Fig. 2
NOTE: 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 thermo- stat. If voltage is present at the element, check element for continu- ity 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 ele-
ment. A low OHMS reading (continuity) should be indicated. If infi nite OHMS (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 el- ement. A low OHMS reading (continuity) should be indicated. If infi nite OHMS (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 se- lected. 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.

OHMS
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 infi nite 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 infi nite switch in the HI posi- tion. If no voltage is indicated at receptacle, check for loose connections, broken wiring, or a defective infi nite switch. If voltage is present at the receptacle terminals, check ele- ment 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 OHMS reading (continuity) should be indi- cated, and this reading may vary slightly on each element tested. If infi nite OHMS (open) is indicated, element must be replaced (see Fig. 3).
