Microwave cavity accumulates condensation or water droplets on walls and door after cooking.

Safety first: Allow the microwave to cool before wiping condensation.

Step-by-step checks:

• 1. Ventilation: Ensure that all external vents are clear and that the microwave has the recommended clearance.
• 2. Wipe dry: After cooking, open the door and wipe away moisture to prevent corrosion and odor.
• 3. Inspect door seal: Check the inner door frame and gasket for damage that could allow steam to condense excessively.

Some condensation is normal, especially with high-moisture foods. Persistent heavy condensation may indicate a fan or venting issue that should be checked by a technician.
