Why is my Sharp R-272M flashing inside?
If you notice flashing or arcing from within the cavity of your Sharp Microwave Oven during cooking, it means a metallic object is too close to the oven cavity. This may roughen the surface of the cavity, but it should not otherwise damage the oven.
How to stop my Sharp R-272M from arcing when cooking potatoes?
If you are experiencing arcing when cooking potatoes in your Sharp Microwave Oven, make sure you remove all "eyes" from the potatoes and pierce them before cooking. Place them directly onto the turntable or in a heat-resistant dish.
Why is there condensation in my Sharp R-272M Microwave Oven?
Condensation may form in your Sharp Microwave Oven and drip from the door because the oven cavity is typically colder than the food being cooked. Steam produced during cooking condenses on the colder surfaces. The amount of steam depends on the water content of the food. Condensation trapped in the door glass should clear after a few hours.
Why is there a draught around the door of my Sharp R-272M Microwave Oven?
When the Sharp Microwave Oven is working, air circulates within the cavity. The door does not form an airtight seal, so air may escape from the door.
