Safety first: Be cautious of hot steam when opening the door.

Check oven vent: Locate the oven vent outlet (often at the top front or rear). Ensure it is not blocked by cabinet trim or foil.
Cooling fan operation: Confirm that the cooling fan runs during and after cooking. If not, test and replace the fan motor.
Use ventilation: Use the kitchen extractor hood or open a window when cooking high‑moisture foods.
Wipe down: After cooking, wipe away condensation to prevent long‑term damage.

Oven cavity has visible water droplets or excessive condensation on glass during and after cooking.
