Home appliances are built to perform strenuous work year after year with usually no problems, therefore they will be easily to take for granted. The result is that when a machine fails, you can be totally at a loss – you do not know how it works, you have no idea why it stopped working, and you probably do not know how to fix it.

What can you do? You can pay a professional for reparation, or you can fix it yourself to save your bills. Our home appliances section will give you all the information you need to know to get your appliances apart and then putting them back together right. But before you attack your washing machine or dishwasher with screwdriver, we will obtain additional information on major appliances.

Most home appliances work on your home’s electrical system. They uses the circuit wiring AC power at home. Small home appliances work on 110-120-volt circuit devices and the plugs on their cords have two blades. Major home appliances such as air conditions, dryers, Tumble Dryers usually require 220-240-volt wiring and cannot be operated on 110-120-volt circuits. Major appliances are connected to a ground wire, their plugs have two blades and a prong. This type of device must be connected to an earth – one with openings to accept both blades and grounding prong – or grounded with a special adapter plug. All appliances are labeled – either on a metal plate or on the appliance casing – with its power requirements in watts, volts, and sometimes in amps.

Small home appliances are usually relatively simple machines. They can consist of a simple heater, fan, a set of blades, or rotating beaters attached to a drive shaft or they may have two or three simple mechanical linkages. Repair to these small home appliances are usually simple. Major appliances are more complex – a large device, like a washing machine may have a motor, a timer, and a pump, as well as various valves, switches, and solenoids. With this type of machine, problems can occur in either the control devices or the mechanical/power components. Failure of a control unit can affect any operation or the entire appliance, failure of a mechanical power unit typically affect only functions that are dependent on this device. When a major appliance breaks down, know-how to diagnose the problem is just as important as knowing how to fix it.

Because large home appliances are so complex, it usually isn’t obvious where a malfunction is. Many newer appliances usually include electronic diagnostics that can be interpreted from its user’s manual. The first step is to decide whether the problem is in a control device or a mechanical device. In a dryer, for example, the control devices govern the heat, and the mechanical components turn the drum. Which system is affected? If the drum turns, but the dryer doesn’t heat, the problem is in the control system. If the dryer heats, but the drum doesn’t turn, the problem is mechanical. This kind of analysis can be used to pinpoint the type of failure whether it’s control system or mechanical system.

To find out exactly where the problem is, make sure to check each part of the affected system to find the malfunctioning part. It is not as difficult as it may seem, because appliance components work together in a logical order. The mere possibility, you can test the components one by one to isolate the cause of the error.
