TROUBLE SHOOTING
Possible Causes / Solutions
• Aluminum foil used on the the broiling pan and grid has not been fitted properly and
slit as recommended.
- See the Broil section in the User's Guide.
• In some areas the power voltage may be low.
- Preheat the broil element for 5-7 minutes
- See the Broiling Guide, page 27 in the User's Guide.
• Oven Sensor needs to be adjusted.
- See thermostat adjustment in the special function section.
• Coarse particles such as salt or sand between cooktop and utensils can cause
scratches.
Be sure cooktop surface and bottoms of utensils are clean before usage. Small
scratches do not affect cooking and will become less visible with time.
• Cleaning materials not recommended for ceramic-glass cooktop have been used.
See Cleaning the Glass/Ceramic Cooktop in the MAINTENANCE section, page
42-43 in the User's Guide.
• Cookware with rough bottom has been used. Use smooth, flat-bottomed cookware.
• Scraping of metal utensils on cooktop surface. Do not slide metal utensils on cooktop
surface. Use a ceramic-glass cooktop cleaning creme to remove the marks. See
Cleaning the Glass/Ceramic Cooktop in the MAINTENANCE section, page 42-43 in
the User's Guide.
• Boilovers are cooked onto surface. Use the blade scraper to remove soil. See
Cleaning the Glass/Ceramic Cooktop in the MAINTENANC section, page 42-43 in
the User's Guide.
• Mineral deposits from water and food. Remove using a ceramic-glass cooktop
cleaning creme. Use cookware with clean, dry bottoms.
• The oven temperature is too high to set a self clean operation.
- Allow the range to cool and reset the controls.
• Oven controls improperly set.
- See the self clean section, page38-40 in the User's Guide.
• A self clean cycle cannot be started if the oven lockout feature is active.
• This is the sound of the metal heating and cooling during both the cooking and Self
Clean functions.
- This is normal.
• A convection fan may automatically turn on and off.
- This is normal.
• Apply a small amount of vegetable oil to a paper towel and wipe the edges of the
ovenracks with the paper towel.
• Convection fan stops during a convection bake cycle.
- This is normal and is done to allow for more even heating during the cycle.
This is not a failure of the range and should be considered normal operation.
