Technical Drawing

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 manufac-
turer cannot be responsible, nor assume any liability, for injury or damage of
any kind arising from the use of this data sheet.
IMPORTANT NOTE: This unit includes an EOC (electronic oven control). This
board is not eld-repairable.
Safe Servicing Practices
To avoid the possibility of personal injury and/or property damage, it is import-
ant that safe servicing practices be observed. The following are some, but not
all, examples of safe 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 elec-
tric outlet, trip circuit breaker to Off, or remove fuse.
3. Never interfere with the proper installation of any safety device.
4. Use only replacement parts specied for this appliance. Substitutions
may not comply 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.

ELECTRIC OVEN WITH MODULAR OVEN CONTROLS
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 uninsulated electrical terminals, connectors, heaters, etc. are ade-
quately spaced away from all metal parts and panels.
• All safety grounds (both internal and external) are correctly and secure-
ly reassembled.
• All panels are properly and securely reassembled.
Temperature Adjustment
Refer to the Use & Care Manual for directions on how to adjust the oven temperatures.
Modular Control Systems
This appliance is equipped with a modular system of controls. The modular system consists
of various boards which communicate with one another to drive cooking functions. Oven
functions, if available, operate through an oven user interface (UI or UIB) and an oven relay
board. Cooktop functions, if available, operate through a cooktop UI/UIB and a cooktop
relay board. There may be additional boards which work within the system to drive specic
functions (refer to the schematics and diagrams and this sheet). Low voltage operating and
communications power for the modular boards is provided through the wiring schemes.
The boards that generate low voltage operating and communications power depend upon
the individual control system (refer to the schematics and diagrams on this sheet). These
voltages are only the operational voltages. Do not use these voltages as conrmation of
communication between the boards. Communication occurs through software programming
on each board. This communication is not detectable by volt ohmmeters. The programming
is self-monitored and the UI displays will show error codes based on detected failures. The
individual boards are not eld repairable. See the schematics and diagrams included on this
sheet for more unit-specic details.
