Appliances are designed to last. They work hard year after year, typically without incident. It's easy to take them for granted. As a result, when an appliance breaks down, you may be absolutely lost: you don't know how it works, you have no idea why it stopped working, and you certainly have no idea how to fix it.
What are your options?
You can either hire an expert to fix it or do it yourself to save money. This guide will teach you all you need to know to disassemble your blocked toilet plumber and then reassemble them in functioning order. But, before you tackle the refrigerator with a screwdriver, let's review some significant appliances.
Most appliances are powered by your home's electrical system, which uses alternating current (AC) current from your home's circuit wiring. Small appliances operate on 110-120-volt circuits, and their plugs have two blades. Air conditioners, dryers, and ranges, for example, typically require 220-240-volt wiring and cannot be operated on 110-120-volt circuits. Large appliances are grounded, and their plugs contain two blades and a prong. This appliance must be plugged into a grounded outlet (one with holes for both blades and a grounding prong) or grounded using a special adaptor plug. All appliances are labeled with their power requirements in watts and volts, and sometimes in amps, either on a metal plate or on the appliance shell.
Small appliances are often simple machinery. They can be as simple as a heating element, a fan, a set of blades, or rotating beaters connected to a driving shaft, or as complex as two or three simple mechanical linkages. Repairs to these items are typically straightforward. Large appliances are more complicated; a washing machine, for example, may include a motor, a timer, and a pump, as well as several valves, switches, and solenoidS. Problems with this type of appliance can arise in either the control devices or the mechanical/power components. Failure of a control device may impact one operation or the entire appliance; failure of a mechanical/power component typically impacts only the functions that rely on that device. When a large appliance fails, understanding how to diagnose the problem is just as vital as knowing how to repair it.
Because big appliances are so complicated, it is often difficult to pinpoint the source of a problem. (Many contemporary appliances contain electronic diagnostics that can be used in conjunction with the owner's manual.) The first step is to determine whether the issue is in a control or mechanical device. The control devices of a dryer, for example, regulate the heat, while the mechanical components revolve the drum. Which systems are impacted? The problem is in the control system if the drum turns but the dryer does not heat. The fault is mechanical if the dryer warms but the drum does not revolve. In all major appliances, this form of study can be utilized to detect the type of breakdown (control system or mechanical system).
To determine the actual cause of the problem, examine each component of the impacted system to identify the faulty component. Because appliance components work in a logical sequence, this isn't as tough as it sounds. Starting with the simplest alternatives, you can isolate the source of the problem by testing the components one by one.
