KitchenAid Range Error Code F1-E1

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.

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.

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.

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.

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.
