Definition and terms  A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy to electrical energy. ... Power supply classfication 1.The DC or Direct Current PS An AC powered unregulated power supply usually uses a transformer to convert the voltage from the wall outlet (mains) to a different, nowadays usually lower, voltage. If it is used to produce DC, a rectifier is used to convert alternating voltage to a pulsating direct voltage, followed by a filter, comprising one or more capacitors, resistors, and sometimes inductors, to filter out (smooth) most of the pulsation..

Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 26 Developed by: Juanito P.Banzon Revision # 01 2.The AC or Alternating Current PS An AC power supply typically takes the voltage from a wall outlet (mains supply) and lowers it to the desired voltage. Some filtering may take place as well. Different kinds of power supply How a power supply works A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. The AC voltage generated is passed through a circuit of four diodes arranged as shown above and emerged converted into a more useful DC output. The Red color indicates that those diodes are in forward bias and the black color indicates that those diodes are in reverse bias. The arrows show the direction of current flow.

To identify the parts and function of toaster. 3. To job sheet on the learners. Over view about oven toaster Think of a toaster oven as a big toaster or a small oven. This Fix-It Guide on toaster oven repair tells how a toaster oven works, what often goes wrong, how to identify a toaster oven problem, and what parts and tools you will need to fix it. It then refers you to simple step-by- step instructions for electrical cord repair, appliance controls repair, heating element repair and other repairs as needed. How Does a Toaster Oven Work? A toaster oven is a small heating appliance that toasts bread, waffles, etc., and may (depending on the wattage) also function as a miniature oven. Some allow you to bake and broil foods, offering precise temperature and function controls. To use a toaster oven, you set the controls, open the door and place food on a shelf, then close the door. When the oven is set to toast, the toaster thermostat regulates the upper and lower heating elements as selected

When set to bake or broil, the bake thermostat controls the heating elements as selected by the temperature controller and possibly by a timing mechanism. Fix-It Tip As with toasters, keeping a toaster oven running longer means keeping it clean of food debris. Clean bread crumbs and other foot particles out of the inside of the oven frequently. The features of toaster ovens vary considerably from model to model. However, most operate in the same manner and can be diagnosed and repaired similarly. What Can Go Wrong with a Toaster Oven? The problems that toaster ovens may present are similar to those of other heating appliances. The electrical cord may need replacing. The main switch, the thermal fuse, and the solenoid may be faulty. The thermostat may be faulty or need recalibrating. How Can I Identify a Toaster Oven Problem?  If the oven doesn’t work at all, make sure the circuit breaker or fuse is on at the electrical service panel and test the electrical cord.  If the oven doesn’t work on its toaster and oven functions, test the main switch (see theAppliance Controls Fix-It Guide). As needed, check the fuse.  If the toaster function doesn’t turn off unless the door is open, test the solenoid, the switch and if necessary, the thermostat (see the Appliance Controls Fix-It Guide).

By Using An Electric Rice Cooker The User Can Quickly Make Some Rice Without Worrying Of Overcooking Or Burning. Many Times People Will Set Up The Rice Cooker In Place Of Pasta Or Potatoes As A Side Dish. Like Many Electrical Appliances The Electric Rice Cooker Can Have Some Problems As It Ages. There Are Electrical Problems That Surface As The Appliances Gets Some Age On It. Many Owners Will Simply Throw It In The Trash And Buy A New One. However,With The Right Types Of Components A Do It Yourselfer Can Easily Fix Their Rice Cooker For Prolonged Use. Step1-Unplug Power Cord From Wall Before You Start To Work On The Electric Rice Cooker You Will Want To Make Sure It Is Not Plugged Into Any Power Source.

Testing Voltage Touch the two test leads to the two metal contacts of a live power source, like a wall outlet or the terminals of the motor that you're testing for voltage. (Do not jam the test leads into a wall outlet!) If you are getting power through the VOM, the meter will jump up and steady on a reading. You may have to convert the scale in your head. For example, if you're using the 250 volt dial setting and the meter has a "25" scale, simply divide by 10; 120 volts would be "12" on the meter. TESTING FOR CONTINUITY
  64. 64. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 58 Developed by: Juanito P.Banzon Revision # 01 Don't let the word "continuity" scare you. It's derived from the word "continuous." In an electrical circuit, electricity has to flow froma power source back to that power source. If there is any break in the circuit, it is not continuous, and it has no continuity. "Good" continuity means that there is no break in the circuit. For example, if you were testing a solenoid to see if it was burned out, you would try putting a small amount of power through the solenoid. If it was burned out, there would be a break in the circuit, the electricity wouldn't flow, and your meter would show no continuity. That is what the resistance part of your VOM does; it provides a small electrical current (using batteries within the VOM) and measures how fast the current is flowing. For our purposes, it doesn't matter how fast the current is flowing To use your VOM to test continuity, set the dial on (resistance) R x 1, or whatever the lowest setting is. Touch the metal parts of the test leads together and read the meter. It should peg the meter all the way on the right side of the scale, towards "0" on the meter's "resistance" scale. If the meter does not read zero resistance, adjust the thumbwheel on the front of the VOM until it does read zero. If you cannot get the meter to read zero, the battery in the VOM is low; replace it. If you are testing, say, a solenoid, first make sure that the solenoid leads are not connected to anything, especially a power source. If the solenoid's leads are still connected to something, you may get a reading through that something. If there is still live power on the item you're testing for continuity, you will burn out your VOM instantly and possibly shock yourself. Touch the two test leads to the two bare wire ends or terminals of the solenoid. You can touch the ends of the wires and test leads with your hands if necessary to get better contact. The voltage that the VOM batteries put out is very low, and you will not be shocked. If there is NO continuity, the meter won't move. If there is GOOD continuity, the meter will move toward the right side of the scale and steady on a reading. This is the resistance reading and it doesn't concern us; we only care that we show good continuity. If the meter moves only very little and stays towards the left side of the scale, that's BAD continuity; the solenoid is no good.
  65. 65. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 59 Developed by: Juanito P.Banzon Revision # 01 If you are testing a switch, you will show little or no resistance (good continuity) when the switch is closed, and NO continuity when the switch is open. If you do not, the switch is bad. Testing Continuity AMMETERS Ammeters are a little bit more complex to explain without going into a lot of electrical theory. If you own an ammeter, you probably already know how to use it. If you don't, don't get one. Ammeters are expensive. And for our purposes, there are other ways to determine what an ammeter tests for. If you don't own one, skip this section. For our purposes, ammeters are simply a way of testing for continuity without having to cut into the system or to disconnect power from whatever it is we're testing. Ammeters measure the current in amps flowing through a wire. The greater the current that's flowing through a wire, the greater the density of the magnetic field it produces around the wire. The ammeter simply measures the strength of this magnetic field, and thus the amount
  66. 66. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 60 Developed by: Juanito P.Banzon Revision # 01 of current, flowing through the wire. To determine continuity, for our purposes, we can simply isolate the component that we're testing (so we do not accidentally measure the current going through any other components) and see if there's any current flow. To use your ammeter, first make sure that it's on an appropriate scale (0 to 10 or 20 amps will do). Isolate a wire leading directly to the component you're testing. Put the ammeter loop around that wire and read the meter. Testing Amperage Washing Machine Repair PROBLEMS COMMON TO ALL WASHER BRANDS Washing machine designs vary widely, but there are some things that all washers have in common. For example, all washers have an electric motor. All washers have both spin and agitate cycles. And since both cycles are driven by the same electric motor, all washers have some sort of mechanism to change between the two. All washers must also have a way of filling the tub with wash water and a way of draining out used wash water.
  67. 67. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 61 Developed by: Juanito P.Banzon Revision # 01 And incidental to this, all washers must have a way of controlling water level in the tub, to prevent spillage by overfill or by centrifugal force during the spin cycle. All washers must (by law) have a mechanism that brakes the spinning basket at the end of the spin cycle, or else a lid lock to prevent the lid from being opened during or shortly after the spin cycle. And last but not least, all washers must have a timer that controls and coordinates the start, stop and duration of the various cycles. CYCLES FILL CYCLE During the FILL cycle, a solenoid-operated water mixing valve opens and allows hot or cold water (or both) to enter the tub. There is no pump operating at this time; the tub fills strictly from house pressure. Similarly, there is no heater in your washer; the heat comes from the water heater in your home. When the water in the tub reaches a certain level, a pressure switch closes the water solenoid valve(s). Typical Drive Train
  68. 68. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 62 Developed by: Juanito P.Banzon Revision # 01 WASH/RINSE (AGITATION) CYCLE After the water valve closes, an electric motor starts which drives the transmission, sometimes through a belt, and in some cases through a clutch arrangement, too. The transmission converts the rotary motion of the motor to the back-and-forth motion of the agitator. A driveshaft extends from the top of the transmission to the agitator, where it is connected to the agitator, usually by a spline. Agitation will continue for a certain amount of time, which is controlled by the timer. During agitation, some washers use their pump to circulate water, sucking it from the bottom of the tub and pumping it to the top of the tub. The pump is driven by the same electric motor. Also during the agitation cycle, bleach or softener may be automatically added. This is usually done by a solenoid valve that allows some of the re-circulated water to flush out the bleach or softener dispenser. In some models there is no water circulation involved; the solenoid simply opens a valve or door that lets the dispenser contents drop into the wash water. The timer tells this solenoid valve when to open. SPIN AND DRAIN CYCLES after agitation comes a drain cycle, sometimes combined with a spin cycle. During the drain cycle, the pump sucks water from the tub and sends it down the drain. During the spin cycle, the same motor that drove the agitator now drives a spin tube which is concentric with the agitator shaft. The spin tube spins the basket, slinging excess water out of the clothes by centrifugal force. There is a clutch arrangement which allows the basket to come up to speed slowly. This prevents a heavy load from being thrown onto the motor suddenly. It also allows a "pre-pump" action; the water has a chance to drain out of the tub before the basket gets up to speed, preventing the water from overflowing the edge of the tub by centrifugal force. Some brands have a partial drain cycle only, then refill and agitate again. Some start spinning and draining at the same time. Some only drain until
  69. 69. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 63 Developed by: Juanito P.Banzon Revision # 01 the water reaches a certain level, and then start spinning. Most brands have lid switches that prevent the basket from spinning when the lid is open. Some brands have a lid lock that prevents you from opening the lid when the basket is spinning. At the end of the spin cycle, or whenever the lid is lifted, most models have a braking arrangement that stops the tub from spinning. This helps to prevent people from accidently sticking their hands into a spinning basket. CAUTION: NEVER BYPASS THE LID SWITCH, EXCEPT FOR TEST PURPOSES. IF IT IS DEFECTIVE, INSTALL A NEW ONE. THEY ARE THERE FOR A REASON. NO JOKE: I PERSONALLY HAVE A NEPHEW WHOSE ARM WAS TORN OFF (AT 2 YEARS OLD) BECAUSE OF A BYPASSED LID SWITCH! FILL SYSTEM The basic components of the fill system are the hoses, the fill valve, and the pressure or float switch. The fill valve is simply a solenoid valve that opens when activated and allows hot and/or cold water to flow into the tub. Most modern washers use dual solenoid valves, which have both hot and cold solenoids in one valve body. When warm water is desired, both valves open to mix hot and cold. Typical Fill Solenoid Valve
  70. 70. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 64 Developed by: Juanito P.Banzon Revision # 01 In the newest digital washers, water temperature may be controlled by a "thermistor." A thermistor is a variable resistor; a resistor whose resistance varies according to what temperature it senses. The thermistor's signal goes to the washer's control board (computer,) which opens or closes hot and cold water valves to control the incoming water temperature. When the water in the tub reaches the desired level, the pressure or float switch closes the circuit to the fill valve. Float switches are pretty rare; you'll find them only in older washers. A diaphragm-type pressure switch is more common. Typical float and pressure switches are shown in Figure. A few old washers used a pressure switch mounted on the BOTTOM of the tub; these are known as water weight switches. They are rare. Typical Water Level Switches

Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 65 Developed by: Juanito P.Banzon Revision # 01 DIAGNOSIS If your washer is not filling properly, or is overflowing, there could be several reasons. SLOW OR NO FILL, OR WATER TOO HOT OR TOO COLD If your washer is filling very slowly or not at all, or the water temperature is always too hot or too cold, check the fill hose and valve strainers. These are little screens placed in the fill hose and/or water valve to prevent rust and scale from your house's piping system from getting into the water valve. The strainers can get clogged up over time and prevent water flow. Shut off the water valves and remove the hoses. Look into the both ends of each hose and into the water valve mounted on the washer. In at least one of the three places you should see a strainer screen. If it is clogged, you can try cleaning it out with a toothbrush and/or a turkey baster. If you cannot clean the screen sufficiently, you may need to replace it.
  72. 72.

Neither is very expensive. Fill Strainer Screens When re-installing the hoses, always use new hose washers. Also, take care not to over tighten the hose on the plastic threads of the solenoid valve; tighten just enough to stop it from leaking. If there is any question about the watertight integrity of the hose, replace it. A hose costs a lot less than a new floor or carpeting, which is what you'll be buying if it breaks while you're not home. If the strainers look O.K., set your temperature control to "warm" and set your timer in the fill cycle. Raise the lid of the washer and depress any lid switch with a pen or screwdriver. Feel the water entering the washer. If it is too hot or too cold, or if no water is coming out at all, test for voltage across each solenoid coil of the water valve. It should read 110 to 125 volts. Checking Voltage across Water Solenoid Valve Coils

Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 67 Developed by: Juanito P.Banzon Revision # 01 If so, you're getting power to your valve, but it's not opening. Replace the valve. If you're not getting power to the valve, refer to the wiring diagram for your machine and trace the source of the interruption. Sometimes it's a broken wire, but more commonly, there will be a problem with the water level switch, timer, lid switch, or temperature switch. Replace the defective switch. If your washer is a late-model digital machine with a fill thermistor, a defective thermistor might be sending the wrong signal to the control board. Replacing the thermistor (they're not too expensive) will usually solve the problem. The control board may also be defective. CAUTION: On some brands, you must raise the top of the cabinet to get to the solenoid valve. If your washer has a mercury-tube type lid switch, raising the top of the cabinet may have the same effect on the lid switch as raising the lid. Your washer may not fill or cycle. You will need to jumper the mercury switch to perform any tests when the cabinet top is raised. OVERFILL As the tub fills, water pressure increases at the bottom of the tub. This
  74. 74. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 68 Developed by: Juanito P.Banzon Revision # 01 pressure is transmitted to the diaphragm in the water level switch by a rubber or plastic tube. When the tub reaches the right level, the diaphragm trips the switch, closing the solenoid fill valve and starting the agitate cycle. Water Level Pressure Tube If the tube or diaphragm is leaking badly, the water level switch will not sense any pressure, and thus will not shut off the water flow, so the tub will overflow. If this tube is leaking slowly, the washer may exhibit odd fill symptoms. For example, depending on how fast the air leak is, the washer may fill and start agitating, then stop agitating and fill some more, then agitate some more, and so forth, until the washer overfills. CAUTION: Whenever you remove the tube from the switch, or insert the tube onto the switch, there cannot be any water in the tub or tube. Before you insert the tube onto the switch, blow into the tube first, to clear it of any water that might have gotten in it. ANY WATER REMAINING IN THE TUBE WILL CAUSE YOUR WASHER TO OVERFILL, OR PROBABLY EVEN TO OVERFLOW! Also test the water level switch electrically, as described in section 2-
  75. 75. Plan Training Session Consumer Electronic Servicing NC-II Date Developed: July 8,2014 Document No. Issued by: SJBFTC Page 69 Developed by: Juanito P.Banzon Revision # 01 6(b). DOES NOT STOP FILLING, AND/OR WATER LEVEL KEEPS GOING DOWN If the house washer drain starts backing up, you get a rooter and clear the drain, right? But some people would just seal it up so it couldn't overflow, instead of clearing the drain, as they should. (Now, WE wouldn't do that, would we, folks?) But that air break between the washer's drain hose and the house's drain pipe is important. If there is no air break, and the drain system fills with water, it can actually start siphoning water right through the pump and down the drain. Depending on how bad the drain is backing up, the washer might never fill completely; the solenoid valve will just stay open and water will just keep siphoning straight out the drain. Or, if the drain is a little more clogged and the water is flowing more slowly, the washer might fill and start agitating, but stop agitating after a few minutes and fill some more. This fill-agitate-fill-agitate cycle will continue for as long as the agitate cycle lasts. And since the power to the timer motor is being interrupted, the wash and rinse cycles may seem unusually long. There is a solution, even if you don't want to root out the drain blockage as you should. Your appliance parts dealer has a drain line vacuum break valve, available for just a few bucks. (Figure G-7) You can cut into your drain line and install one of these vacuum breaks pretty easily. When the drain line is under pressure, (like when the pump is pumping out) the flapper valve closes and no leakage occurs. When the drain line is under a vacuum (like when the drain is trying to siphon it) the flapper valve opens and air is allowed into the drain line, breaking the siphoning action.

For example, 6. All washers have an electric motor. 7. All washers have both spin and agitate cycles. And since both cycles are driven by the same electric motor, 8. All washers have some sort of mechanism to change between the two. 9. All washers must also have a way of filling 10. The tub with wash water and a way of draining out used wash water. And incidental to this, all washers must have a way of controlling water level in the tub, to prevent spillage by overfill or by centrifugal force during the spin cycle.
