Microwave interior fills with condensation or water droplets during and after cooking.

Steps:

• Normal behavior: Some condensation is normal, especially when cooking high-moisture foods. Wipe the interior dry after use.
• Ventilation: Ensure vents are not blocked and the microwave has adequate clearance.
• Door seal: Inspect the door gasket and inner frame for damage or warping that could allow excess steam to escape into the door area.
• Drying: Leave the door slightly open after cooking to allow moisture to evaporate.
