Description of Fault Code |
Solution for Fault Code |
4 Digit Failure Codes (for 2 digit codes see below) |
F1 – E0 |
EEPROM communication error |
1. Power should be turned off for at least 30 seconds. 2. Reapply power and examine for at least a minute. 3.Replace the control board if the code reappears (also called ERC or clock). Note: Except for F1-E3, applies to all F1-E… codes. |
F1 – E1 |
EEPROM checksum error |
F1 – E2 |
UL A/D error(s) |
F1 – E4 |
Model ID error |
F1 – E5 |
Calibration shifted |
F1 – E6 |
Latch signal mismatch error |
F1 – E9 |
Stack overflow |
F1 – E3 |
Wiring harness cavity size does not match previously stored value |
The “Cavity Size Select” jumpers in the wire harness represent a different cavity size from the one for which the control was previously set up. Make sure the jumpers in the harness match the size of the real oven by checking them. |
F2 – E0 |
Shorted keypad (also called touch pad) |
1. Verify a firm connection at the keypad connector (keypad connects to control board). 2. Click CANCEL. Replace the keypad if the error code reappears after 60 seconds (also called touch pad or membrane switch). Some variants combine the control board and keyboard into a single device. Replace the control board here (also called ERC or clock). |
F2 – E1 |
Keypad cable unplugged |
F2 – E5 |
Cancel key drive line open |
F2 – E6 |
Cancel key drive line open |
F3 – E0 |
Oven temperature sensor (RTD) opened (upper oven, if double oven) |
Oven temperature sensor (RTD) needs to be replaced.
Note: Applies to all F3-E… codes.
|
F3 – E1 |
Oven temperature sensor (RTD) shorted (upper oven, if double oven) |
F3 – E2 |
Oven temperature is too high (Cook mode) |
F3 – E3 |
Oven temperature is too high (Clean mode) |
F3 – E4 |
Oven temperature sensor (RTD) opened (lower oven, if double oven) |
F3 – E5 |
Oven temperature sensor (RTD) shorted (lower oven, if double oven) |
F3 – E6 |
Warming drawer sensor open |
F3 – E7 |
Warming drawer sensor shorted |
F4 – E1 |
Meat probe malfunction – shorted |
The probe, the receptacle, or the probe circuit could all be at fault. test probe Inspect the wire for nicks. Check the probe receptacle for dampness or contamination. If everything seems good, replace the probe. |
F5 – E0 |
Door switches do not agree (condition exists when door switch is closed indicating an open door, and latch switch is closed indicating a locked door) |
1. If door latched: A. Remove the unit’s power source. B. Inspect the cables and connectors that run from the control to the door switch and then back to the control. If there is no wire damage and every connector is in good condition, move on to step C.C. Change the door switch. D. Re-apply power.E. Press and hold any key down for 1 minute to clear F5 failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct. 2. If door not latched: A. Disconnect power from unit.B. Check wires and connectors from control to latch switch, then from latch switch to control. If no damage to wires and all connectors okay, proceed to step C. C. Repeat steps A and B for door switch. 3. Measure door switch (door open = switch open small low voltage terminals). Replace switch if defective. 4. Measure latch switch (unlatch = switch open, CAUTION – oven light contacts are closed). Replace switch if defective. 5. If corrections are made in any step, reconnect power to control. Press and hold any key for 1 minute to clear R failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct. 6. If failure remains, disconnect power and replace control. Note: Applies to all F5-E… codes. |
F5 – E1 |
Self clean latch will not lock |
F5 – E2 |
Latch during CLEAN error |
F5 – E5 |
Self clean temperature not reached within 45 minutes. |
F5 – E6 |
Door is open, but latch is locked |
F5 – E7 |
Self clean latch will not unlock |
F6 – E0 |
Return line not connected |
Within 60 seconds of powering up, the electronic control will display F6 if the switch pulse return line is not connected. Change the control. |
F7 – E1 |
Common switch wire is defective |
Latch switch and door switch common wires (+5VDC) are shorted to chassis ground or neutral. A double oven will have one common wire and two of each switch.
1. Check connections at control and at the latch switch and door switch. 2. If all connections are good, then check the individual switches as outlined for the F5 failure.

2 Digit Failure Codes |
F0 |
Board failure |
Replace control board (also called ERC or clock). |
F1 |
Board failure |
Replace control board (also called ERC or clock). |
F2 |
Oven temperature is too high |
1. Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC). 2. For SELF CLEAN models: check door lock operation. 3. Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective. Remember: Oven control (ERC) measures resistance of sensor circuit, not actual oven temperature. |
F3 |
Oven temperature sensor (RTD) open |
Replace Oven temperature sensor (RTD) |
F4 |
Oven temperature sensor (RTD) shorted |
Replace Oven temperature sensor (RTD) |
F5 |
Board failure |
Replace control board (also called ERC or clock). |
F7 |
Function key stuck on ERC |
Replace control board (also called ERC or clock). |
F8 |
Board failure |
Replace control board (also called ERC or clock). |
F9 |
Oven door lock failure |
Check wiring to door lock switch (the wire harness may be connected wrong). Check for stuck lock switch. |
