A flashing fault code and a four-beep signal will
occur within a brief period after attempting to use
the oven or microwave function that uses the
failed sensor (humidity sensor or thermistor). If a
sensor fails during cooking, the oven or
microwave function will be terminated immediately,
and the display and signal will occur.
Detection of a failed sensor will have no effect on
functions that do not use that sensor.
Pressing the Clear key will remove the fault code
display. This does not apply to the control panel
short detection.
Sometimes fault codes will appear with no
apparent cause. These codes and their
symptoms include:
•
F1 - When cooking in Oven/Bake or
Speedcook mode, the main PCB will monitor
the thermistor output after 20 minutes of
operation. If the thermistor does not read a
temperature of 165° F or greater, then an F1
fault code will signal, and operation will
terminate. If a large cold load is being cooked,
the thermistor may not reach the needed
165° F within the 20-minute time period, thus
the main PCB will read this information as the
thermistor not responding and will display the
F1 code. If the consumer reports an F1 fault
code, it will take an extended amount of time to
duplicate.
•
F4 - If there is an electrical surge or excessive
line “noise” within the home, it could cause F4
to display on the control. The sensor will
remain inoperable until the control is reset. This
can be done by removing power (turning off
the circuit) to the unit for 1 minute. Replacing
the humidity sensor will not cure this situation
if it was due to electrical “noise.”
Diagnosing Cooking Problems
An important part of diagnosing any consumer
cooking concern is listening carefully to the
consumer describe the problem. Equally important
is asking the consumer the right questions. The
following diagnostic information is intended as a
guide for you to follow when addressing cooking
concerns.
Food Items Appear to Be Undercooked
Foods which appear to be undercooked or
partially cooked can be the result of any one of the
following items. The possible causes listed below
are sorted from most likely to least likely, with item
number 1 being the first item that you should
check.
1. Is the consumer selecting the correct type of
cooking (microwave vs. Speedcook), and/or is
the consumer using the correct time and
power levels for the type, size, and quantity of
food being cooked?
2. Is the consumer using the correct cookware
for the type of food being cooked?
3. Is the consumer arranging the food properly on
the metal cooking trays?
4. Is the turntable operating properly so that
microwave energy and halogen heat are being
evenly distributed to the food?
5. Are the damper doors closed in Speedcook
and Oven/Bake? If the damper doors are
open in Speedcook or Oven/Bake, heat will
escape from the oven and it will not be able to
maintain the proper temperature. Perform
damper door test.
6. Confirm proper line voltage to the unit (check
voltage under full load).
7. Confirm that voltage compensation is
operating properly.
8. Perform a microwave performance test to
confirm that microwave energy output (HV/
magnetron circuit) is operating to specification.
9. Are all fan motors operating properly? During
