How to fix it

  1. Open the door and close it firmly.
  2. Reset power: turn off the circuit breaker(s) for one minute, turn them back on, and watch the microwave for one minute to see whether the code returns.
  3. If F5 E1 returns, schedule service. Do not open the microwave cabinet or test parts inside it: it holds a high-voltage capacitor that can stay charged after unplugging.

Why it happens

Typical signs: F5E1 on the display · Cycle aborts with an audible 'thunk' from the latch · Door feels loose or doesn't 'pull' shut
