how to repair major appliances - home appliance manufacturer

The equipment was built for execution.
They work hard year after year, usually without too many problems.
They are easily taken for granted.
As a result, you may be completely overwhelmed when a device is broken-
You don't know how it works, you don't know why it stops working, and you certainly don't know how to fix it. What can you do?
You can pay the professional to fix it, or you can fix it yourself and save money.
This article will provide you with all the information you need to know, take your main appliance apart and put it back together in order of work.
But before you attack the refrigerator with a screwdriver, let us know the background information of some major appliances.
Most appliances operate on your home's electrical system: they use AC current in your home circuit wiring.
Small household appliances work 110-120-
Voltage circuit, the plug on The Wire has two blades.
Large or large appliances such as air conditioners, dryers and stoves usually require 220240-
Voltage wiring, not at 110-120-volt circuits.
Ground wire wiring for large electrical appliances;
Their plug has two blades and one plug.
This type of device must be plugged into a ground socket--
One with an opening that can accept both Blade and ground prong--
Or ground with a special adapter plug.
All appliances are labeled-
On the metal plate or on the equipment case--
In Watts and Volts, sometimes in amps.
Small appliances are usually quite simple machines.
They can be made up of simple heating elements, fans, a set of blades or rotating mixers attached to the drive shaft;
Or they may have two or three simple mechanical connections.
The repair of these appliances is usually relatively simple.
Larger appliances are more complex--
A main equipment such as a washing machine may have motors, timers and pumps, as well as various valves, switches and solenoid.
With this type of equipment, problems may occur with the control equipment or mechanical/power components.
The failure of the control equipment may affect one operation or the whole equipment;
The failure of the mechanical/power unit usually affects only the function that depends on the unit.
Knowing how to diagnose a problem when a major device fails is as important as knowing how to fix it.
Because the main appliance is so complex, it is usually not obvious where the fault occurs. (
Many newer devices include electronic diagnostics that can be explained from the user manual. )
The first step is to decide whether the problem lies with the control device or the mechanical device.
For example, in the dryer, the control device controls the heat, and the mechanical part turns the drum.
Which system is affected?
If the drum turns but the dryer is not hot, the problem is in the control system.
If the dryer is heated but the drum does not turn, the problem is mechanical.
This analysis can be used to determine the type of failure--
Control system or mechanical system--
Of all the big appliances
To find out exactly where the problem is, each part of the affected system must be checked to find the part that failed.
This is not as difficult as it sounds, as the device components work together in a logical order.
Starting with the simplest possibility, you can test the components one by one to isolate the cause of the failure.
You have to follow three very important rules when you are trying to do any type of electrical repair.
Don't try to save time or money by ignoring these rules.
You won't save anything at all and you may end up hurting yourself or destroying the device.
Equipment Service Center, equipment-equipment parts provided
Repair dealers and equipment-parts stores.
You don't have to go to a particular brand all the time.
Name the electrical parts Center for the parts and services required by the brand
So you have some shopping/service options.
If you can't find the parts service center in your area, order the parts you need directly from the manufacturer.
The name and address of the equipment manufacturer are usually printed on the equipment.
Be sure to provide the manufacturer with all models and part data of the equipment.
If so, search for replacement parts on the Internet.
Please make sure the appliance receives the power supply before performing any electrical repair.
Insufficient power is the most common cause of electrical failure.
Take these preliminary steps before you start the testing and diagnostic process: OK, now that we're not ready for the preliminaries, it's time to start.
