SERVICE DATA SHEET
Electric Ranges with 3XX Electronic Oven Controls
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.
Oven Calibration
Set the electronic oven control for normal baking at 350°F. Obtain an average oven temperature after a minimum of 5 cycles. Press Stop/Clear/Cancel to end bake mode.
Temperature Adjustment
1.Press Bake.
2.Set the temperature to 550°F (288°C) by pressing and holding the UP arrow key.
3.Within 3 seconds, press and hold Bake until numeric digit(s) appear.
Release Bake key. The display now indicates the amount of degrees offset between the original factory temperature setting and the current temperature setting. If the oven control has the original factory calibration, the display will read 00.
4.The temperature can now be adjusted up or down 35°F (19°C), in 5°F increments. Press and hold the UP arrow key to adjust the temperature higher until the desired amount of offset appears in the display. When lowering the oven temperature using the DOWN arrow key, a minus sign (-) will appear before the number to indicate that the oven will be cooler by the displayed amount of degrees.
5.When you have made the desired adjustment, press OFF to go back to the time of day display.
Note: Changing calibration affects normal Bake mode. The adjustments made will not change the Self-Cleaning cycle temperature.
