When the oven is working, air circulates within the cavity.
The door does not form an airtight seal so air may escape from the door.

The oven cavity will normally be colder than the food being cooked, and so
steam produced when cooking will condense on the colder surface.
The amount of steam produced depends on the water content of the food
being cooked. Some foods, such as potatoes have a high moisture content.
Condensation trapped in the door glass should clear after a few hours.

Arcing will occur when a metallic object comes into close proximity to
the oven cavity during cooking. This may possibly roughen the surface of
the cavity, but would not otherwise damage the oven. 

Ensure all “eyes” are removed from the potatoes and that they have been
pierced, place directly onto the turntable or in a heat resistant flan dish or
similar.

Check the door is closed properly.

Ensure correct power level has been selected.

The microwave energy pulses ON and OFF during cooking/defrosting.
