Oven turns off and displayes F2,F3,and sometimes F4.

F4 Oven temperature sensor (RTD) shorted Replace Oven temperature sensor (RTD)

The F2, F3 and F4 codes refer to problems with the oven temperature sensor or the keypad. If you see the two-digit F2 code, it means your keypad has shorted and the ERC must be replaced. The four-digit F2-E0 code means that the oven temperature is too high. Test the door lock and the relay operation, and correct as necessary. A two-digit F3 code means an open temperature sensor or thermal fuse, so those parts must be replaced. A four-digit F3-E0, F3-E1, F3-E2 or F3-E3 code or a two-digit F4 code means that either the oven is registering as too hot or the temperature sensor has shorted. Either way, the oven temperature sensor must be replaced.
Hope helps.

Just two work there:
1.- Replace the touchpad or the clock (ERC) if the code "F1" is displayed. Disconnect the ribbon connector to the touchpad. If no code is displayed after an hour, replace the touchpad. If the code displays again, replace the clock.
2.- Replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.

Hi, replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.

KitchenAid ovens are popular for their classic design and simple user interface. When a problem occurs in the function of a KitchenAid oven, an error code will display on the clock as soon as the malfunction registers in the oven's memory. Each code corresponds to a particular type of malfunction. Most can be corrected by disconnecting the power supply for one minute and then restarting. If the code persists, either replace the indicated part or contact a service center. F0/F1

The F0 and F1 codes refer to electrical issues. If the code appears as only two digits, the problem is a transistor failure, so you must replace the electronic range control (ERC). If the code displays four digits, it will read F0-E0, which indicates a failure switching from analog to digital, or F1-E1, which refers to a safety flip-flop. Both problems require the replacement of the ERC.

F2/F3/F4

The F2, F3 and F4 codes refer to problems with the oven temperature sensor or the keypad. If you see the two-digit F2 code, it means your keypad has shorted and the ERC must be replaced. The four-digit F2-E0 code means that the oven temperature is too high. Test the door lock and the relay operation, and correct as necessary. A two-digit F3 code means an open temperature sensor or thermal fuse, so those parts must be replaced. A four-digit F3-E0, F3-E1, F3-E2 or F3-E3 code or a two-digit F4 code means that either the oven is registering as too hot or the temperature sensor has shorted. Either way, the oven temperature sensor must be replaced.

F3 is Open oven temperature sensor circuit.
F4 Shorted oven temperature sensor circuit .
F7 Component failure.

To fix this you need to read oven temperature sensor circuit at oven temperature sensor ( approx 1000 ohms at room temp); check for cut or pinched wire or loss of contact, if wirings are ok, then replace the probe.
