What E-X1 means

Additional open error is the entire listing for E-X1 on Samsung US microwaves, with the characters shown exactly as written. We read it as an open circuit on an extra input, one beyond the main sensors, but the listing does not say which input that is. The oven shows the code and may stop certain programs while other modes keep working.

Common causes of E-X1

  • An extra input circuit that reads as open
  • A loose or broken wire at a sensor or switch
  • Moisture near a connector
✓ One safe check you can try

1. Note exactly what the display shows, including the character after the E. 2. Unplug the oven or switch its breaker off and let moisture dry. 3. Give it a full minute before powering on. 4. Try a short timed cook with a cup of water. 5. If the code returns, request service.

! Why to stop there
  • Without a named part, we have to identify which extra input your model carries before testing it.
  • The model number and the exact display help us do that quickly.
  • You see the price in writing before work starts.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E-X1E-X1 questions
What does the X mean?

The listing prints it just that way and does not explain the X. The wording is all we have, so we identify the real input from your model and the way the oven behaves.

Is the oven usable?

If timed cooking runs normally after the reset, yes, with care. Avoid any program that stops and shows the code, and do not keep restarting it.

What should I tell you when I call?

Give us the model number and what the display shows exactly. That lets us work out which input the code points to before we visit.
