My kitchenaide convection oven is displaying the E1 F4 error.
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.
