Microwave shows E15 and beeps continuously; door may not unlock on some built-in models.

Safety: Unplug the appliance before attempting to adjust or remove the door. The door is a critical safety component for containing microwave energy.

Steps:

• 1. Inspect door alignment: Check that the door closes evenly and sits flush with the cabinet. If it rubs or sags, adjust the hinges according to the IKEA installation guide.
• 2. Check latch operation: Open and close the door while listening for a firm click from the latch. If the latch feels loose or does not engage, the latch assembly may be broken.
• 3. Visual inspection: On some models, you can see the latch hooks from inside the cavity. Look for cracks or missing pieces.
• 4. Manual release (if locked closed): Consult the user manual for the emergency door release procedure. Do not force the door open with tools, as this can damage the interlock system.

Resolution: Replace the door latch assembly or door lock motor (if fitted) with the correct IKEA-compatible part. After replacement, perform a door leakage test (technician) to ensure safety.
