F9E0 — Miswired Electrical Supply

This code most often means the oven is wired incorrectly at the home electrical supply or at the hard-wire connection — for example, L2 and Neutral swapped. It can also appear from electrical noise after a power outage, or from keys being pressed during the power-up delay.

How to fix it

  1. Kill power at the breaker for at least 1 minute, then restore and wait before touching the control.
  2. If F9E0 clears, it was a power-event artifact — no wiring problem.
  3. If it returns, have a qualified electrician verify the wiring at the home electrical supply and the hard-wire connection, including that L2 and Neutral are not swapped.
  4. Correct any miswiring at the source before re-energizing the oven.
  5. Once the supply is verified correct, restore power — the code should clear. If it doesn't, the control board may have been damaged by the incorrect wiring and will need replacement.

Why it happens

  • Electrical noise after a power outage A brownout or surge from a recent power event can trigger the code without any actual miswiring.
  • Keys pressed during the power-up delay Pressing buttons during the initial power-up delay window can trigger F9E0 on some models.
