Microwave cavity has excessive condensation or water droplets after cooking.

Safety first: Condensation itself is not dangerous, but ensure the unit is unplugged before cleaning.

Steps:

• 1. Wipe cavity: After cooking, wipe down the interior with a dry cloth to remove moisture.
• 2. Check vents: Ensure that the exhaust vents on the sides or top are not blocked by cabinets or objects.
• 3. Run fan: If your MasterChef model has a vent fan option, run it for a few minutes after cooking to help clear moisture.
• 4. Internal fan check (experienced DIYers): Verify that the cavity cooling fan operates during cooking. Replace if not running.
