Microwave shows E10 and beeps; door appears closed but unit refuses to start.

Safety: Unplug the microwave before adjusting any mechanical parts.

Door inspection:

• Open the door and inspect the plastic latch hooks at the top/side. Look for cracks, bending, or wear.
• Close the door slowly and observe alignment with the cabinet; the door should close evenly without rubbing.
• Gently lift and lower the door to check for excessive hinge play.

Minor adjustments:

• Tighten any accessible hinge screws (on some Fagor models, hinges are accessible from the side or top once trim is removed).
• If the latch hook is slightly bent, it may be carefully realigned, but replacement is preferred if damaged.

Internal latch bracket (qualified):

• Remove the outer cover and locate the latch bracket that holds the door switches.
• Ensure the bracket is firmly secured and not cracked.
• Replace the latch bracket or door assembly if alignment cannot be restored.

Do not attempt to defeat the door safety system. If E10 persists, have a professional evaluate the door and latch system.
