Microwave cavity accumulates condensation or water droplets after cooking.

Steps:

• After cooking, open the door for a few minutes to allow steam to escape.
• Wipe down the interior with a dry cloth to remove moisture.
• Ensure vents are not blocked and that the microwave has adequate clearance.

Some condensation is normal, especially with high-moisture foods. Persistent heavy condensation may indicate poor ventilation; improve airflow around the unit.
