Baking results are not as expected

Refer to cooking charts for recommended rack position. Check “Getting the 
Most out of Your Oven” for tips and suggestions. Adjust oven calibration if 
necessary (see “Change the Oven Temperature Offset” in this manual).

Food takes longer to cook than expected

The oven is carefully calibrated to provide accurate results. However, the 
temperature can be offset if food is consistently too brown or too light. See 
“Change the Oven Termperature” Offset”. 

Food is overcooked

The oven is carefully calibrated to provide accurate results. However, the 
temperature can be offset if food is consistently too brown or too light. See 
“Change the Oven Termperature” Offset”. 

Convection Bake or Convection Multi-
Rack Results are not as Expected

If the Automatic Convection Conversion Feature is turned off, the 
temperature must be manually reduced by 25°F. If the feature is active, the 
temperature is automatically adjusted. See “Turn Automatic Convection 
Conversion ON or OFF” for more information. Refer to cooking charts and 
tips for rack positions, cooking times and pan selection. Adjust oven 
calibration if necessary. See“Change the Oven Termperature” Offset”.

Oven temperature is too hot or too cold

The oven thermostat needs adjustment. See Oven Temperature Offset. 
See “Change the Oven Termperature” Offset”.

Oven light is not working properly

Replace or reinsert the light bulb if loose or defective. Touching the bulb 
with fingers may cause the bulb to burn out.

Oven light will not turn off

Check for obstruction in oven door. Check to see if hinge is bent. When the 
Sabbath feature is activated, the oven light will stay on or off (as selected 
during set-up) during the entire Sabbath mode.

Cannot remove lens cover on light

There may be soil build-up around the lens cover. Wipe lens cover area 
with a clean dry towel prior to attempting to remove the lens cover.

Oven will not Self-Clean properly

Allow the oven to cool before running Self-Clean. Always wipe out loose 
soils or heavy spillovers before running Self-Clean. If oven is badly soiled, 
set oven for a four-hour Self-Clean. See Preparing the Oven to Self-Clean.

Clock and timer are not working properly

Make sure there is electrical power to oven. See Clock and Timer sections. 

Porcelain chips

When oven racks are removed and replaced, always tilt racks upward and 
do not force them to avoid chipping the porcelain.

“F” and a number appears in display and 
control beeps

This is a fault code. Press Off to clear the display and stop beeping. Reset 
oven if necessary. If fault code remains and beep continues, record fault 
code, cancel oven and call authorized service technician.

With a new range there is a strong odor 
when oven is turned on

This is normal with a new range and will disappear after a few uses. 
Operating the self-clean cycle will also “burn-off” the smell more quickly.

Control does not react when the pad is 
touched

Be sure that pad is clean. Touch the center of the touchpad. Use the flat 
part of your finger.

Fan is running during modes that don’t 
use convection

On some models, the convection fan will run while the oven is preheating 
for the bake mode. This is normal.
Slide-in models also have a cooling fan that runs during every cooking 
mode.

Warm air or steam escapes from oven 
vent

It is normal to see or feel steam or warm air escaping from the oven vent. 
Do not block the vent.

Cooling fan runs after oven is turned off 
(Slide-in ranges only)

This is normal. When the oven has cooled to a pre-determined 
temperature, the cooling fan turns off.

The cooktop does not operate during Self-
Clean

This is normal for some models. Operation will return once Self-Clean is 
complete.
