Keen cooks may want to take advantage of multi-function ovens - usually aimed at the top end of the market. As well as traditional cooking, fan or fan-assisted cooking and grilling, these ovens offer up to nine further functions. These include: Top element only (browning), bottom element (final cooking of pastry dishes or pizzas), fan and bottom element (delicate cooking), fan only (thawing).

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.
