How to fix it

  1. Kill power at the breaker for 1 minute and restore as a first attempt.
  2. If F1E2 returns immediately, the board has failed — there is no field-serviceable fix.
  3. Replace the electronic oven control board.
  4. Inspect the home supply for surge issues and consider a whole-house surge protector to protect the new board.
  5. After replacement, run a 350F bake test to confirm normal operation.
