Failure
Code
Meaning
Correction
-F0-
Shorted OFF key
(Membrane) or GT Error
Perform glass touch board key panel test. Determine if problem
is with key panel or control by disconnecting ribbon cable and
measuring
fl
at cable pins 13 to 14. Should be open. Should be 100-
150
Ω
while pressing OFF key.
-F2-
Over temperature
Inside oven cavity as
measured by sensor over
600°F (315°C) unlatched
or 915°F (491°C) latched
.
Welded relay contacts
•
Cooling fan stalled or blocked
•
Air
fl
ow to rear of unit
•
High resistance in oven sensor leads/connectors (especially at
•
sensor rear)
-F3-
Open oven sensor (under
950
Ω)
Disconnect power. Disconnect sensor harness from control.
•
Measure sensor resistance (white leads) to be -1080
Ω
at room
temperature with 2
Ω
per degree change.
Look for damaged harness terminals if not a bad sensor.
•
-F4-
Shorted oven sensor
(over 2900
Ω
)
Disconnect power. Disconnect sensor harness from control.
•
Measure sensor resistance (white leads) to be -1080
Ω
at room
temperature with 2
Ω
per degree change.
Separate sensor from harness to determine fault.
•
-F7-
Shorted matrix to START
key
Determine if problem is with key panel or control by disconnecting
ribbon cable and measuring
fl
at cable using pinout chart. Allow up to
1000
Ω
when pressing key.
-F8-
EEPROM data shift failure If repeated, replace control
-F9-
Cooling fan stalls while
above 650°F (343°C);
open thermal switch in
yellow or blue leads
Cooling fan or air
fl
ow to control area.
-FF-
Loss of latch motor safety
circuit
Replace control.
ERC Failure Codes
The ERC (electronic range control) has error (F) codes that can be utilized by the service technician in order
to quickly identify failed or improper operation of certain oven components. The oven may stop operating
but not give an F code on the display immediately. A fault must exist continuously for 5 minutes before an F
code is recorded (F2, F8 are sooner). F codes are stored in nonvolatile EEPROM memory until the same fault
occurs twice consecutively.
F codes can be recalled by pressing together TIMER, CLOCK, MIN DOWN or 9. While F codes are displayed,
pressing MIN UP or 8 and HR DOWN or 6 together will clear them. To exit failure code mode, press upper
oven START pad.
Note:
If an "FO" failure code is displayed and the buttons do not work, disconnect power to the range.
Wait 5 seconds then reconnect power to the range. Press the “Bake” and “Broil” keys simultaneously
until “SF” appears in the display. (You are now in the Special Features function.) Press the “9” and “0” keys
simultaneously for 5 seconds. Wait until time of day is displayed. Press “1” and “5” keys simultaneously. The
display will: go blank, brie
fl
y display all LED segments, brie
fl
y display “Loc rEF”, display all segments for 30
seconds, and then display “LOC REF”. Then press “6” and “8” keys simultaneously and the control will display
time of day. Verify control operation by pushing several keys at random to ensure they all work.
When
fi
rst plugged in, if all display segments illuminate for approximately 7 seconds, then Loc rEF appears
in the display, and none of the pads work, proceed to step #5 then #6.
