In earlier days appliance repair was simpler and could be done by anyone. Today, however, some repair knowledge is required to allow you to change some faulty parts in your appliances. For example, take the dryer, a common appliance. First of all you need to ask yourself just what the problem appears to be. For instance is your dryer doing nothing? Is it making funny clunking sounds, is it too hot, not hot, is it making a grinding noise as you turn it off or on? The answers to these questions will allow you to begin to search the Internet to find out what others have found to be their problem and thus get a heads-up as to where exactly to begin. Of course, you will have checked first to make sure the unit is plugged in and also that it has not tripped a circuit breaker or blown a fuse.
Another important tip is that all home appliances are labeled in one way or another; sometimes on the appliance itself, or on a metal plate affixed to the appliance. This label will tell you the model number of the appliance, and the power requirements, expressed in watts and volts required, and often in amps.
If you wish to test that the power is actually reaching the unit, you may avail yourself of a multimeter. A multimeter may be known as multitester, but it may also be known as a volt/ohm meter or VOM. What it does is to measure power flow in electronic circuits as well as current and resistance. It is a necessary tool for troubleshooting problems in any appliance. A cheap one may cost you only $15 or so, but as today's appliances grow more sophisticated, you may wish to invest in a slightly better tester. Multimeters can run you as high as thousands of dollars depending on how sophisticated it is. Most people in the appliance repair business now use digital multimeters rather than the old fashioned analog ones. Thankfully, the purchase of a multimeter will also come with directions on how to operate one too.
Small appliances are naturally easier to take apart as well as to diagnose. It's the larger appliances such as a dryer that may be more complicated than you wish to deal with. However, in a dryer, there are usually two alternatives to follow. Usually it is a mechanical or power component, or it is a control issue. What's interesting here is that if you read your owner's manual, there is often a list of suggestions listed for that particular appliance's failures. This will prove extremely valuable, and sometimes it is a problem that is easily fixed!
Before attempting any repairs or taking apart any appliance you will obviously make sure that the electricity or the gas is no longer connected. Also, if you find that the appliance is put together with screws, plugs, or bolts, then you can safely take it apart to diagnose problems and make repairs .Should you decide that there is a malfunctioning part, it's usually easy to search the Internet to find a particular part to for a particular small appliance. Don't be afraid of shopping the item either, as prices will be quite divergent, as are shipping costs.
