DANGER WARNING

Electrical Shock Hazard Electrical Shock Hazard Disconnect power before servicing. Only authorized technicians should perform diagnostic Replace all parts and panels before operating. voltage measurements. Failure to do so can result in death or electrical shock.

After performing voltage measurements, disconnect power before servicing.

Failure to follow these instructions can result in death or electrical shock.

Voltage Measurement Safety Information

When performing live voltage measurements, you must do the following: Verify the controls are in the off position so that the appliance does not start when energized. Allow enough space to perform the voltage measurements without obstructions. Keep other people a safe distance away from the appliance to prevent potential injury. Always use the proper testing equipment. After voltage measurements, always disconnect power before servicing.

Temperature Adjustment

Step Function Keypad Pressed Notes 1 2 Temperature adjustment Press BAKE for 5 seconds The current offset, if any, is shown in the display U-00. The offset range is from +30°F to -30°F (+17°C to -17°C). 3 Temperature adjustment options (Depending on model) Adjust temperature in 10°F (5°C or 6ºC) increments. Temp/Time or Temp/Hour Bake temperature adjustment cannot result in operating Press “MORE” or “LESS” arrow keys temperatures higher than 500°F (260°C) or 525°F or (275°C), depending on the model, or lower than 170°F (75°C), as measured at the oven center. Press “+” (plus) or “-” (minus) arrow keys Once the bake temperature has been adjusted, broil temperatures are automatically offset to the same degree.

Activate temperature adjustment Press START Desired temperature adjustment is activated. If Start is not pressed within 1 minute, adjustment is ignored.
