What F1-E1 means on a KitchenAid range

F1-E1 on a KitchenAid range is an EEPROM checksum error that occurs during startup. The control board reads stored configuration and calibration data from its EEPROM memory chip at power-on, then runs a checksum to verify data integrity. When the checksum does not match the expected value, the board logs this as a silent fault, meaning it will not display the code on the control panel. It is captured in the board's fault log and requires a diagnostic mode or service tool to retrieve it. The primary suspect is the electronic control board itself.

For homeowners, the EEPROM is a small memory chip built into the control board that stores settings for your range, including calibration data and configuration values. When the range powers on, it checks that this stored data is valid. If the data has become corrupted or the memory chip has failed, the board flags the mismatch. Because this fault is silent, you may not notice a visible error code, but the range could behave erratically, fail to start certain functions, or lose stored settings like oven temperature calibration.

This fault is generally tied to control board hardware failure, not to user error or simple fixes like a power reset. A failed or corrupted EEPROM on the board is not field-repairable and typically requires replacing the entire control board assembly.

Common causes of F1-E1

  1. 01

    Failed EEPROM on control board

    Part replacement

    The EEPROM memory chip soldered onto the control board has failed or its stored data has become corrupted, causing the checksum to fail on every startup. This is the most direct hardware cause of F1-E1 and requires replacing the control board.

  2. 02

    Power surge or voltage spike damage to control board

    Part replacement

    A voltage spike from a power surge can corrupt the data stored in the EEPROM or damage the control board's memory circuit, triggering this checksum mismatch at the next startup. The board will continue to log the fault on each power-on cycle.

  3. 03

    Corrupt EEPROM data from improper power interruption

    Wiring / connection

    If power to the range is cut at the exact moment the board is writing data to the EEPROM, the stored values can become corrupted. A power cycle or reset will not resolve this since the corrupted data persists in non-volatile memory.

Frequently asked questions about F1-E1

What does F1-E1 mean on a KitchenAid range?
F1-E1 means the control board detected an EEPROM checksum mismatch at startup. The EEPROM is the memory chip on the control board that stores calibration and configuration data. The board checks this data every time the range powers on, and when the stored checksum does not match, it logs F1-E1 as a silent fault. Because it is a silent fault, it will not appear on the display and must be retrieved through diagnostic mode.
How do I fix F1-E1 on a KitchenAid range?
The fix for F1-E1 is almost always replacing the electronic control board. The fault points to a failed or corrupted EEPROM on the board, which is not repairable in the field. Before ordering a board, verify the fault code by entering diagnostic mode to confirm F1-E1 is logged. If confirmed, replace the control board with the correct part number for your model.
Can I still use my KitchenAid range if it has an F1-E1 fault logged?
Possibly, since F1-E1 is a silent fault and may not prevent basic operation immediately. However, a corrupted EEPROM can cause unpredictable behavior including incorrect oven temperatures, failure to hold settings, or other control malfunctions. Continued use is not recommended without diagnosing and addressing the fault, especially for baking or any cooking that depends on accurate temperature control.
How much does it cost to fix a KitchenAid range F1-E1 error?
The main cost is the electronic control board, which typically ranges from $150 to $350 depending on the model. Professional labor to diagnose and install the board adds roughly $100 to $200. If you are comfortable with appliance repair, replacing the control board yourself is a moderate DIY job requiring basic hand tools and careful handling of ribbon cables and wiring harnesses.
Will resetting my KitchenAid range clear the F1-E1 fault?
A power reset will not clear F1-E1 because the EEPROM checksum mismatch is a hardware condition, not a temporary software glitch. Each time the range powers on, the board re-reads the EEPROM and will log the fault again if the data remains corrupted. Clearing the fault log through diagnostics will only remove the logged entry temporarily; the fault will return on the next startup until the control board is replaced.
