Microwave exterior or control panel becomes very hot to the touch during normal use.

User-level steps:

• Ensure that all vents on the sides, rear, and top are unobstructed.
• If built-in, verify that installation follows Balay's specified clearances and ventilation paths.
• Avoid running multiple long, high-power cycles back-to-back; allow cooling periods.

If the microwave still overheats or shuts down, a technician should check the cooling fan and internal airflow channels.
