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.
Touch UPPER CANCEL or LOWER CANCEL or turn power off at the
circuit breaker. Wait 5 minutes and turn it back on. If condition persists,
note the code number and call an authorized servicer.
This is caused by close contact to the control panel for more than 60
seconds, such as someone leaning against the controls or objects hanging
in front of controls. See item above for correction.
The fan turns off automatically when the electronic components have
cooled sufficiently.
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 Calibrating
Oven Temperature, Page 28). Refer to cook charts for recommended rack
position. Always reduce recipe temperature by 25°F when baking with
Convention Bake mode.
The oven thermostat needs adjustment. See Calibrating Oven Temperature,
Page 28.
Replace or reinsert the light bulb if loose or defective. See Page 37.
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 spill-over before running Self-Clean. If oven is badly soiled, set
oven for a four-hour Self-Clean. See Preparing the Oven to Self-Clean, Page 31.
Make sure there is proper electrical power to the oven. See the Clock
and Timer sections on Pages 12 and 13.
When using Bake mode, preheat the oven first. Convection Bake and
Convection Roast will eliminate any moisture in oven (this is one of the
advantages of convection).
When oven racks are removed and replaced, always tilt racks upward and
do not force them to avoid chipping the porcelain.
