Added features such as ice making and drinks dispensers can all add to the appeal of certain models. Ice making is an option on many American style fridge-freezers, sometimes available without opening the door, as are cold water dispensers. Zoned models offer several storage areas, all at different temperatures, designed to keep a variety of foods fresh for longer.

The insulation on electrical cords can become damaged by wear, flexing, or age. Do not use any cord that is stiff or cracked. Some clues that you may have an electrical problem are:

• Flickering lights. If the lights dim every time you turn on an appliance that circuit is overloaded or has a loose connection.
• Sparks. If sparks appear when you insert or remove a plug, they could be a sign of loose connections.
• Warm electrical cord. If an electrical cord is warm to the touch, the cord is underrated or defective.
• Frequent blown fuses or broken circuits. A fuse or circuit breaker that keeps tripping is an important warning sign of problems.
• Frequent bulb burnout. A light bulb that burns out frequently is a sign that the bulb is too high a wattage for the fixture.
