FAILURE
CODE MEANING CORRECTION
-F2
-
Inside oven cavity as measured by sensor
over 650°F unlatched or 915°F latched
• Welded relay contacts
• Airflow to rear of unit
• High resistance in oven sensor leads/connectors
(especially at sensor in rear)
Oven temperature
-F3-
• Disconnect power. Disconnect sensor harness from control. Measure
sensor resistance (white leads) to be 1080 ohms at room temperature
with 2 ohms per degree change.
• Look for damaged harness terminals if not a bad sensor.
Open oven sensor
(over 2900 ohms)
Shorted oven sensor
(under 950 ohms)
-F4-
• Disconnect power. Disconnect sensor harness from control. Measure
sensor resistance (white leads) to be 1080 ohms at room temperature
with 2 ohms per degree change.
• Separate sensor from harness to determine fault.
Shorted key
-F7-
Check logic display assembly. If rubber button pad is misaligned, correct;
otherwise, replace control.
-F8-
EEPROM data shift failure
If repeated, replace.
-F9-
Cooling fan stalls or other cause of open sail switch
Suspect stalled cooling fan or airflow
to control area.
-CX-
-C1-
-C4-
Communication Error
Check harness first and then replace
component indicated by Cx Error Code.
-FC-
Door Latch Error
Inspect door latch and circuitry.
Replace if switches are defective.
The last 7 Failure (F) codes are stored in the nonvolatile memory, accessed through the factory test mode. All
Failure (F) codes are suppressed from the display, except F2 and F9.
To access the last 7 F-codes, follow these steps:
1. Enter the factory test mode. (See Factory Test Mode.)
2. Press the Timer button to cycle through the factory test mode options.
3. Find the F-code menu. The display will show “F-co”.
4. Press the Mini-Knob button to enter this menu.
5. Press the Mini-Knob button to cycle through F-codes. Press the Timer button to return to the factory test
mode main menu.
Communication errors stored:
C1 – Communication Fail with Main Relay Board
C2 – Communication Fail with Upper Temp Encoder
C3 – Communication Fail with Upper Mode Encoder
C4 – Communication Fail with Aux. Relay Board
C5 – Communication Fail with Lower Temp Encoder
C6 – Communication Fail with Lower Mode Encoder
