Self Help - Oven
“F” and a number appears in display and control beeps
With a new range there is strong odor when oven is
turned on
This is a fault code. If a “F” code flashes, 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 servicer.
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.

The knob was turned too rapidly. Turn knob slower until
correct wording or temperature appears. Review manual
instructions when setting clock, timer, or Self-Clean.
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.
Check the circuit breaker or fuse box to your house. Make
sure there is proper electrical power to the oven. Make
sure the oven temperature has been selected.
Check oven calibration. Adjust calibration if necessary
(see Oven Temperature Offset). Refer to cooking charts
for recommended rack position. Always reduce recipe
temperature by 25°F when baking with Convection Bake
mode.
The oven thermostat needs adjustment. See Oven
Temperature Offset.
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.
There may be a soil build-up around the lens cover. Wipe
lens cover area with a clean dry towel prior to attempting
to remove the lens cover.
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.
Make sure there is proper electrical power to the oven.
See the Clock and Timer sections.
When oven racks are removed and replaced, always tilt
racks upward and do not force them to avoid chipping the
porcelain.
