The microwave cavity fills with excessive steam or condensation during cooking, with water droplets forming on walls and the door.

Safety: Condensation itself is not dangerous, but it can lead to corrosion or electrical issues if excessive.

Steps:

• 1. Wipe down: After cooking, wipe moisture from the cavity walls and door with a dry cloth.
• 2. Ventilate: Leave the door open for a few minutes after use to allow moisture to escape.
• 3. Check vents: Ensure external vents are not blocked and the room is well ventilated.
• 4. Door seal: Inspect the door gasket and sealing surfaces for damage or warping. Replace if the seal is compromised.
