Solving Operational Problems

POTENTIAL CAUSES AND SOLUTIONS
The numbers were touched too rapidly. Be sure you remove your finger
from the first number pad before touching the next digit.
Touch OVEN OFF or turn power off at the circuit breaker, wait 3 minutes
and turn the oven back on. If condition persists, note the code number
and call an authorized service technician.
This is caused by close contact to the control panel for more than 60 seconds,
(i.e.; someone leaning against the controls or objects hanging in front of
controls). Follow guidelines for "F followed by 2 digits", above.
Oven is in Sabbath mode. To turn off sabbath, touch OVEN OFF.
This is normal. The fan turns off automatically when the electronic
components have cooled sufficiently.
Make sure there is proper electrical power to the oven.
See the Clock and Timer sections on Pages 9 and 10.
Make sure there is proper electrical power to the oven.
Check the circuit breaker or fuse box to your house.
Replace or reinsert the light bulb if loose or broken. See Page 53.
Touching the bulb with your fingers may cause the bulb to burn out
quickly. Oven light does not work if Self Clean mode is set. Oven light
cannot be turned on or off while sabbath mode is in operation.
Try suggestions in "Solving Baking Problems, page 55. Adjust oven
thermostat. See Calibrating Oven Temperature in Do-It-Yourself
Maintenance, Page 54.
Verify that self clean mode was properly programmed. See "Self Clean
Mode Operation, page 49). The oven temperature is too high to set the
self clean operation. Allow the oven to cool to room temperature and
reset the controls.
This is normal during and after self clean. Allow the oven to cool below the
locking temperature.
Heavily soiled ovens may require a second self clean for a longer
period of time. Heavy spillovers should be cleaned before starting
the clean cycle. See Before You Self Clean, Page 48.
Do not run Self Clean. Call for service. See Page 54.
Extendable Rack was left in oven during self clean. Apply a small amount
vegetable oil to the rack support areas to facilitate rack extension and
removal. Color change is permanent. To order a replacement Extendable
Rack, phone Thermador Customer Support at (800) 735-4328.
