What causes the F1E1 code on a Whirlpool oven?

Power surge corrupted EEPROM data: Storms, generator switchover, or breaker bounce can scramble the saved settings. Failing onboard memory or microcontroller: If the checksum fault returns immediately after every reset, the EEPROM chip itself has failed. Loose or oxidized power connection at the board: An intermittent supply can cause repeated brownout writes that eventually corrupt memory.

F1E1 — EEPROM checksum error

The control board's stored calibration/settings (EEPROM) failed its checksum on power-up. The control no longer trusts its own configuration and locks out cooking.

How to fix it

Disconnect power at the breaker for at least 30 seconds (Whirlpool's documented reset).
Restore power and wait a full minute before pressing anything.
If F1E1 clears, run a quick bake test at 350F to confirm normal operation.
If F1E1 returns, replace the electronic oven control board — the EEPROM is not separately serviceable.
After replacement, recheck the home's voltage and grounding so a future surge doesn't kill the new board.

Why it happens

Typical signs: F1E1 on the display, often right after a power blip · Oven will not enter bake, broil, or self-clean · Clock may be frozen or showing dashes
