ELECTRONIC OVEN CONTROL FAULT CODE
DESCRIPTIONS
Note: Only three fault codes are displayed by this control "F1", "F2", "F3" and "F9". Generally speaking "F1" implies a
control failure, "F2" is a communication problem, "F3" an oven probe problem, and "F9" a latch motor problem. In all
occurrences the alarm is accompanied by a display of "F1". To see the exact description of the fault code, unplug the appliance
and plug it again. When PF appears on the control, touch both BAKE and BROIL pad at the same time for 3 seconds, then
touch the KITCHEN TIMER pad.
Fault Code
Likely Failure Condition/Cause
1. (F10) Control has sensed a potential
F1
runaway oven condition. Control may
have shorted relay, RTD sensor probe
may have gone bad.
2. (F11) Shorted keypad.
3. (F13) Control's internal checksum may
have become corrupted.
F2
1. (F21) Communication problem with the
auxiliary board.
2. (F23) Communication problem with
the TST board.
1. (F31) Open RTD sensor probe/ wiring
F3
problem. Note: EOC may initially display
an "F1", thinking a runaway condition
exists.
2. Shorted RTD sensor probe / wiring
problem. Note: "F3" is displayed when
oven is in active mode or an attempt to
enter an active mode is made.
3. Abusive operation (safety thermostat).
4. Safety thermostat opened, or cooling
fan stalled.
1. Door motor failure / jammed. Latch
F9
motor switch failure.
2. Control software failure, or component
failure (relay stuck).
3. Wiring Problem.
Suggested Corrective Action
1. Check RTD sensor probe and replace if necessary. If oven is
overheating, disconnect power. If oven continues to overheat
when the power is reapplied, replace EOC. Severe overheating
may require the entire oven to be replaced, should damage
be extensive.
2. Press CLEAR key.
3. Disconnect power, wait 30 seconds and reapply power. If
fault returns upon power-up, replace EOC.
1. Verify wiring between controller (P4 and P10), auxiliary
board (P1) and glass panel (J1).
2. If F21 appears, replace auxiliary borad.
3. If F23 appears, replace glass panel.
4. It is possible that the controller does not communicate with
the auxiliary board. If it is the case, change the controller.
1. Press CLEAR key.
2. Check wiring in probe circuit for possible open condition.
Check RTD resistance at room temperature (compare to
probe resistance chart). If resistance does not match the
chart, replace the RTD sensor probe.
3. Let the oven cool down and restart the function
4. Look for stalled cooling fan, broken safety thermostat
(opens).
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power for
30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch A and Door
Switch circuits.
4. Unplug P4, apply power (L1) directly to the Lock Motor, if the
motor does not rotate, replace Lock Motor Assembly. Plug
P4.
5. Check Lock Switch A for proper operation (do they open and
close, check with ohmmeter). The Lock Motor may be
powered as in above step to open and close Lock Switch. If
the Lock Switch is defective, replace Motor Lock Assembly.
6. If all above steps fail to correct situation, replace control.
