even after cooling

Turn the oven off at the circuit breaker and wait 5 minutes. Turn breaker 
back on. The oven should reset itself and will be operable.

Oven is not heating

Check circuit breaker or fuse box to your house. Make sure there is proper 
electrical power to the oven. Be sure oven temperature has been selected.

Oven is not cooking evenly

Adjust oven calibration if necessary (see “Change the Oven Temperature 
Offset” in this manual). Refer to cooking charts for recommended rack 
position. 

Baking results are not as expected

Most Out of Your Oven” on page 36 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 Temperature Offset” on page 12. 

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 Temperature Offset” on page 12. 

Convection Bake 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 Temperature Offset” on 
page 12.

The oven thermostat needs adjustment. See Oven Temperature Offset. 
See “Change the Oven Temperature Offset” on page 12.

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.

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.

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 five-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.
