On KitchenAid ovens and ranges, F9 (or F9 E0) means the home outlet or hard-wire connection may be miswired, F1 means a problem with the oven temperature sensor, control or wiring, and many other displays — LOC, SAB, PF, C, CAL and a blank clock — are settings or messages, not breakdowns. KitchenAid shows codes as F# E# or E# F#. Its first fix for most is a power reset.
Codes KitchenAid documents
| Display | What KitchenAid says | First action |
|---|---|---|
| F9 or F9 E0 | The home outlet or the connection to the appliance may be miswired; can also follow power-outage voltage noise | Reset power; call an electrician if the oven was recently installed |
| F1 | Problem with the oven temperature sensor, the control or the wiring | Reset power to the product |
| F2 E0 | Keypad disconnected | Reset power; service if it returns |
| F3 E0 | Main sensor open or shorted | Reset power; service if it returns |
| F5 E0 | Door and switch do not agree (Clean mode) | Reset power; service if it returns |
| C | Display is in Celsius instead of Fahrenheit | Change the setting in the manual |
| Blank clock | A hidden option hides the time of day | Hold Clock Set/Start for about five seconds |
| CAL | Oven calibration feature | See the manual |
| LOC, Lock, Locked | Control lock is on | See the manual to turn it off |
| SAB, Sab, 5AB or 5A6 | Sabbath mode is on | See the manual to exit it |
| PF, or time flashing | A power failure occurred | Press Cancel; reset the clock |
KitchenAid’s own pages list many more F-codes (F0, F2 E1 to F2 E6, F3 E1 to F3 E4, F5 E1 to F5 E7, F6, F7 and F8 groups) and wall-oven codes such as 1c, 1d, 3d, 4d and FC, but we could not read the meaning of each, so we cover only the ones above rather than guess.
F9 and F9 E0: Wiring or voltage
This is the code most often seen right after a new oven is installed. Whirlpool, which owns KitchenAid, describes it the same way, and our Whirlpool oven error codes guide covers it. KitchenAid also notes that during a power outage, unexpected line noise can trigger it, in which case a reset clears it. If the oven is new and the code persists, call an electrician to verify the supply.
F1: Temperature sensor
The oven temperature sensor is the thin probe at the back of the cavity. KitchenAid says F1 can be the sensor, the control or the wiring, and its advice is to reset power first. If the oven heats poorly or runs hot in the meantime, see oven not heating, oven heats unevenly and oven takes too long to preheat.
F2 E0 and F5 E0
F2 E0 reports that the keypad is disconnected, which usually means the ribbon between the panel and the control has loosened or failed. F5 E0 means the door and its lock switch do not agree during a clean cycle; see self-clean cycle problems and oven door won’t close.
Codes that are not faults
C is just Celsius mode, a blank clock is a hidden display setting, CAL is the calibration feature, LOC is the control lock and SAB is Sabbath mode. Press Cancel after a power failure to clear PF. None of these needs a repair.
How to reset
- Press Cancel/Off
Try the function again.
- Switch the oven’s breaker off for a minute
Restore power and let the control restart.
- Test with a simple bake
If the same code appears, write it down for service.
Codes not listed here
If your display shows a code not in the table, check your owner’s manual or KitchenAid’s product help for your exact model. For a general overview of range faults, see oven not working: troubleshooting guide.
When to call for service
Sensor, keypad, door-switch and control codes that survive a reset need a technician. See our oven repair cost guide before deciding between repair and replacement.
