When a major appliance goes bust, many people go to the store and buy a new one immediately. But with new high-tech appliances costing thousands of dollars, a simple $75 to $100 fix can bring your refrigerator, dishwasher or washer/dryer back to perfect working order and save you money. The life cycle of major appliances like fridges, freezers, ranges, dishwashers, washers and dryers is between 10 and 15 years. A window box air conditioner lasts about seven years. If your appliance falls within those spans, consider a repair before replacement.
