A major appliance is a large machine, such as a washing machine, dryer, refrigerator, freezer, dishwasher or oven, that accomplishes some sort of large household or industrial task. Small appliances, such as microwave ovens, toasters and food processors, perform smaller tasks and are somewhat portable. Many appliances are found in the kitchen: cooktop, range, garbage disposal, and trash compactors to name a few. When an appliance breaks down, the homeowner can either call in a professional to repair it or do it himself or herself, commonly referred to as DIY for “do it yourself”. You'll need the proper parts, repair know-how for all types of appliances, such as dishwasher, microwave oven, stove, range, cook top, washing machine, dryer, garbage disposal, trash compactor, ice maker, humidifier, and dehumidifier. If you're not too handy and need to call in an appliance repair expert for parts and service, you need to do your research on local and global companies based on quality of work, referrals, cost, honesty and integrity, and speed of service for appliances such as a dishwasher, refrigerator, or microwave oven. You can find appliance repair by looking in your local phone book or by searching online directory listings for a professional near you. If you are good at DIY, first try and locate the original service manual of your appliance. There may be a warranty on the appliance. If not, troubleshoot and see if you can locate the source of the problem. It may involve replacing a part or performing a simple repair. Consult a manual on appliance repair, which can be obtained in stores, libraries or on the Internet. Refrigerators and dishwashers, the largest of the kitchen appliances, may frequently be in need of repair due to excessive use, especially if you have older models.
