how to repair small appliances - small home appliances
Power supplies power to small appliances and other electrical equipment.
Overheating of Current equipment (Usually black.
Neutral wire and return (Usually white)wire.
The power of the moving current is called voltage.
In most home systems, the hotline voltage is about 120 V and the white line voltage is zero.
The voltage difference between the two wires moves the current and supplies power to the device.
There are three types of small, portable or household appliances.
Some appliances, such as a toaster and coffee machine, will heat up something.
Other appliances such as food processors and vacuum cleaners also move something.
Some appliances, such as hair dryers, have both.
In this article we will tell you how to fix all these appliances etc.
First of all, though, we will provide an overview of repairing small appliances.
The heating equipment converts electrical energy into heat for toast, heating coffee, drying hair or performing other beneficial tasks.
This heat is generated by passing current through a special wire called a component.
Since this element makes it difficult for electricity to pass through it, some of its energy becomes hot.
Electricity, for example, consumes so much energy to overcome the resistance of the toaster elements that it will emit bright red color to bake the bread.
The common heating equipment involved in this article includes a toaster, a toaster oven, a drip coffee machine, and a filter coffee machine.
Heating equipment that follows the same principles includes clothing irons;
Electric frying pan, pan and waffles;
Convection oven; deep fryers; slow cookers;
Food Dehydrator; rice cookers; steam cookers; indoor grills;
Coffee machine and cappuccino coffee machine;
Iced tea master;
Once you 've learned how to troubleshoot and repair the most popular heating equipment, it's easy to repair either.
The motor converts electric energy into motion.
This power off and mix food, turn on cans, grind waste, collect dirt and move air.
The motor converts electric energy into the magnetic energy of the rotating shaft.
There may be a blade or other accessory at the end of this shaft to do the actual work.
The motor equipment introduced in this paper includes food mixers and mixers, electric tank opener, garbage processor and vertical and tank vacuum cleaners.
Other motor appliances with similar operations include juicer, coffee maker, ice cream maker, electric knife, curling knife, electric pencil sharpener, electric clock, fan, humidifier and foil-Head and rotation
Electric cutter head.
Some small appliances are heated and moving.
The most popular is the electric toaster.
It mixes the dough and bake it into bread.
Bread manufacturers also include diagnostic electronic equipment that helps owners to troubleshoot and repair, so these are not included in this article.
Other combined appliances include hair dryers and stir popcorn.
Almost all small appliances are powered by 120.
This means that many of the problems that may arise with the toaster can also occur through a garbage processor and a hair dryer.
These problems are caused by circuit breakers or fuses, switches and plugs or wires that are grounded or loose.
In this article, you will learn how to easily solve many common problems with small household appliances starting with repairing wires.
The equipment wires power the equipment.
The wires are usually made up of two or three wires and one plug.
Connect the electrical end of the wire with a metal connector or fastener, such as an electrical nut.
The wires used in electrical wires have different diameters or specifications.
The thicker the line, the lower the gauge. That is, a 12-
Specification wire is thinner than 10gauge wire.
Most small electrical appliances use copper wire, hot insulation for copper wire
Resistant to plastic.
A device with a small number of amps required to operate, such as a lamp, usually has two-18-wireor 16-gauge wire. Higher-

The Prong device plug includes a circular prong for grounding and ensures that the hot and neutral prong is inserted into the correct socket slot.
The rated power of most small household appliances is less than 15 am ps.

The amp line can be inserted.
On the other end of the wire, inside the small appliance, the wire is connected to a switch or controller.
The wire can be connected with solder and twisted by electricity-
On the nut or connector.
These connectors physically and electrically connect the power supply to the device.
The connection can be made with a curl connector, clip or shovel connector, or U-or O-connectors.
The internal electrical wire is usually smaller than the one used for the wire, which means the meter number is higher.
To test the device's power cord or wire, first make sure it is disconnected from any power supply or capacitor.
The Continuity tester or multimeter is then used to ensure it is fully powered on.
After connecting the tester, move the wire to ensure that the broken strands that cause intermittent shorts do not appear.
Also check the quality and bending of wire or wire insulation.
If there is any break or crack that may eventually expose the strands, replace the wires with wires or wires of equivalent ratings and specifications.
Electricity entering small household appliances must be controlled: turn on, off, or change depending on temperature, time, or function.
This is what electrical controls do.
Electrical controls include switches, thermostats, rheostat, and timing mechanisms.
Controller is the culprit in many small household appliance problems.
So, before you start taking apart the toaster or vacuum cleaner, let's see how the small appliance control works ---
What to do when they don't.
Most small appliance switches are manually activated to control the current flow in the appliance. A single-
Push or move the pole switch to turn the power on or off.
The multi-position switch allows to set the flow, such as the multi-speed switch for the mixer.
The thermostat turns the circuit on and off to provide current depending on the temperature.
The simplest one is a bimetal thermostat that uses two bonded metals with different thermal ratings.
For example, at room temperature, the length and shape of the two metals are the same, allowing contact at the contact points in the circuit.
Heat bend one of these two metals so that they separate the contacts, open the circuit and stop the current passing through.
Thermostats can be used to turn on or off heating elements or motors.
In fact, the thermostat is used as an overload protector, which turns the circuit on and off if the motor is overheated or overloaded.
The rheostat is a variable controller.
That is, it flexibly controls the electrical flow to the device components.
The mixer with speed control can be used to increase or decrease the speed of the motor, using rheostat to do this.
Because the rheostat is damaged by moisture, it is easy to fail.
In this case, they must be replaced with rheostat of the same type and function.
The rheostat is also called a potentiometer or a "basin ".
"Timing mechanisms control current based on mechanical or digital timing devices similar to clocks.
The timing device in the coffee machine can provide fresh coffee in the morning.
In most cases, the timing mechanism turns on or off small appliances.
When the timing device is not turned on, one of the components to be checked first is the timing mechanism.
Some can be repaired and some must be replaced.
The equipment control can be easily tested using the continuity tester.
By putting the clip at the input, the tester probe at the output, and activating the controller, you can determine if the control is working properly.
For variable controllers, it may be easier to display resistance changes using a multimeter.
Most defective control devices for small household appliances should be replaced instead of repaired.
After removing the controller from the device, bring the part along with the model and serial number of the device to the device-
Parts dealers or electronic stores to ensure a suitable replacement is found.
A switch with a higher amplifier rating or a rheostat with a higher ohm rating can damage the heating element or motor of the device.
This can also be dangerous for operators.
Where can I find a replacement for small household appliances?
First, check your owner's manual to identify the model number and part number.
You may have some equipment if you live in or near the metropolitan area
Purchased parts store.
Of course, call them first to determine if they own or are able to get the type of part you need.
Then put the defective part aside. by-
Compared to the side of the replacement part
Check the game before you buy it.
As a last resort, you can write to the manufacturer.
In most cases, they will introduce you to a regional device --parts dealer.
Since most small appliances are made up of similar components, it is easy to solve any problems once you have the basics.
However, there are specific tips for each small household appliance that may come in handy.
Let's see how to fix the toaster first.
