 How do Electric Ranges work? Most electric ranges are very similar. Before looking at the problems with electric ranges, it is important that you have an understanding of how they work.A heating element is designed to generate heat by resisting electricity .elements on a cook top and elements in the oven that heat up when electricity travels through them.On the cook top you usually have 4 to 6 elements that heat up for cooking in pots and pans. There are three types of elements that are used today. The popular is the coil element. This type of heating element is flat or slightly rounded coiled wire. Heating elements are usually made from nichrome an alloy of nickel and chrome. When the heating element receives electricity, it glows red hot. In most cases, these types of element plug into receptacles which allow them to be removed for cleaning or replacement. A few older models have wired-in coil elements. These bypass the receptacle. Ranges with coil elements have drip pans below them. These help reflect heat and provide an area that can collect any spills. Another type of burner is commonly referred to as Euro burners. These burners are solid and smooth. They heat with electricity also, but do not glow red when in use. They can get very hot, The third style is the radiant element. This style has a glass or ceramic top which covers the heating elements. Be careful to use flat cooking pots and pans. If you don’t use flat pots and pans, the temperature limiter may kick in, turning the heating element off to help prevent damage to the cook top, Their temperature controlled by an infinite switch. Simply by turning the switch between low and high settings, you can increase and decrease the electrical current to the electric burner. This will adjust the temperature of the heating element.Operation of the oven is almost as basic. In the oven, there are two elements. The one on the top of the oven is used for broiling and the one on the bottom of the oven is used for baking. There are two main controls on older electric ranges. The thermostat controls the temperature, and the selector switch lets you select between bake, broil, self-clean, and timed-bake. Some of the selector switch features may be part of the thermostat or more than one control. The thermostat is located directly behind the knob that you set the oven temperature with. It is attached to a thin copper tube which goes down into the oven compartment. This tube is full of a special liquid that when heated expands pushing on a contact point in the thermostat turning the power on and off to the heating element thus regulating the heat.In the past, clocks were usually manual and worked with the selector switch and thermostat to set a time for the oven to come on and a time for it to turn off. Clocks today are usually electronic, and in some cases have taken over the control functions of the thermostat and selector switch. They connect to an oven temperature sensor to determine what the oven temperature is. The control sends more or less electricity to the broil and/or bake elements as needed. These types of clocks are usually referred to as Electronic Oven Controls (EOC) the keypad that you use to set the EOC, along with the EOC itself can only be replaced, not repaired. On some models the keypad is available separately from the EOC and on the others it is one integrated part.Some ovens are referred to as convection ovens. Convection style ovens have a circulating fan that moves the air all around the inside of the oven. Because the air is constantly moving and mixing itself, it makes sure of an even cooking temperature throughout the oven, and this will help cook your foods more evenly and thoroughly. Some of these ovens include a heating element built right into the circulating fan. This can help to prevent hot spots caused by a stationary heating element. Most ranges have a light inside the oven compartment. The switch on the oven door turns the light on when you open it. Some models also have a manual switch on the range top that will let you turn the light on. It is very important to use the proper pan size and pan material for the cooking you are doing. It’s common for people to use over-sized pans, but the outer edge of the pan or pot should be no more than one inch outside of the surface cooking area.

How do Dryers work?   GENERAL   . Most dryers work very similar. Hopefully this information will help you understand how most dryers work. Dryers use either a gas flame or an electric heating element to generate heat; a blower pulls the heat through the drum and then exhausts it while the heat gets drawn through the drum it gently heats the clothes causing the moisture to evaporate into the exhaust air. The dryer use’s a series of thermostat’s and safety devices to control the temperature of the drum so not scorch or burn the clothes. A timer is used to set a time limit on the duration of heat and tumbling time. A motor is used to turn the exhaust blower and drum by use of a drive belt. Older model dryers used a belt to drive a blower assembly  newer dryers utilize a direct drive blower wheel attached directly to the motor shaft .the motor has a centrifugal switch that wont allow any heat to come on if the motor’s not running. The timer control has a cool down cycle towards the end of a cycle witch shuts off the heat but continues to tumble  for approximately 10 minutes cooling the cloths. The dryer has safety devices installed to prevent over heating and possibly a fireDo not bypass these safety features there for your protection..      MACANICLY    .Timer turned to heat cycle contact point’s complete circuit for motor and heat source, power circuit for motor go’s to safety start switch then through door switch to motor some model dryer‘s have a thermal fuse that break the circuit. Heat circuit go’s through the motor’s centrifugal, switch then through the temperature control switch then to the selected thermostat  through the high limit safety thermostat to the heat source. Later model dryers use a thermal fuse to interrupt the circuit. The burner assembly can be removed from the dryer and most service shops can bench test for problems On gas burners with hot surface ignition (most popular) igniter comes on and will glow a bright orange, the flame sensor is satisfied theirs enough heat to ignite gas .Sensor allows magnetic coils on gas valve to be energized, gas flows to igniter ignites. At this point igniter turns off. Gas continues to burn keeping flame switch satisfied until thermostat shuts burner off.  The process on electric dryers is simpler when the thermostats call for heat the heating element heats up until thermostats are satisfied ( constant burning pilot burners ) if pilot wont stay lit the pilot safety latch needs to be adjusted or replaced this should be done by a professional. Models with a (spark ignition) the flame sensor is very sensitive on these models and should be inspected by a professional.

  How do Gas Ranges work? A control valve witch controls the amount of gas to flow to a burner is ignited by either a standing pilot or electric ignition.  The oven works similar just with automatic controls for controlling the oven temperature. Such as the mechanical thermostat with a probe in the oven cavity or an electronic control with sensors.  There are safety features on the oven controls to prevent the flow of raw gas there are burners on the cook top and one or two burners in the oven which burn gas that has been ignited by a pilot, spark igniter, or glow style igniter.On the cook top you usually have 4 to 6 burners with grates over them that allow you to cook in pots and pans. Gas flows from the main gas regulator valve to a manifold that has a corresponding number of burner valves. The gas is brought from the burner valve to the burner through a venturi tube. The burner control knob attaché’s directly to the burner valve. This valve controls how much gas is sent to the burner. To get a larger flame, you send more gas to the burner. The venturi tube between the burner valve and the burner allows the gas to properly mix with air for clean combustion. The air and gas mix then flows into the burner where the pilot flame or igniter ignites it. On models with a spark ignition, there is usually a spark switch attached to the burner valve, which completes the power circuit to a spark module and the spark igniter.  Almost all older cook tops with unsealed burner units allow you to raise the entire top for cleaning and service. Newer cook tops have a sealed burner which has the burners attached to it and requires disassembly to raise the top.  The oven use’s a thermostat to control the temperatures of the oven by mechanical or electrical means. With mechanical, the gas comes from the thermostat to a pilot safety control located in the oven which assures a standing pilot is present to lite the gas after the gas ignites the oven cavity will heat up a probe filled with a special liquid attached to the thermostat as the liquid expands it will slowly cut off the gas flow to the oven according to the set temperature, as the liquid cools it allows gas to flow back to the oven thus regulating the temperatures by turning it on and off. With electrical thermostat’s the thermostat still use’s a probe to determine the oven temperatures in most case’s  the use of a automatic ignition such as glow coil, spark, or hot surface igniter is used along with a flame switch or electrical safety valve.If you smell raw gas when range is not in use open doors and window’s and calls your gas company immediatelyRepairPartsWorld.com

How do Refrigerators work?

All residential refrigerators operate in a similar fashion. Refrigerators with an automatic defrost cycle use heaters in strategic places to defrost ice buildup. The basic principle of refrigeration is that you remove heat. The refrigeration process is really simple. Your refrigerator takes warm air and makes it cooler by transferring the heat using evaporation principles.

Refrigeration starts with the compressor. The compressor is turned on when electricity is sent to it by the thermostat. It mechanically compresses a refrigerant gas. This compression causes the gas to become hot, under high-pressure Next, this hot gas flows through the condenser coils where it dissipates its heat, and condenses into a liquid.

The condenser coil resembles a radiator that you would see in a car. The high-pressure gas from the compressor flows into the condenser coils and changes state to become a liquid. As this change takes place, the tubes radiate heat from the refrigerant gas. This heat is conducted away from the coils by either natural air flow or the assistant’s of a fan ( condenser fan ) . Next the cooled gas is pushed through the capillary tube this tube look’s like a copper wire at first glance but it act’s as a orifice controlling the amount of gas going into the evaporator. The capillary tube connects the condenser coils to the evaporator coils.

As the refrigerant exit’s the capillary tube, the liquid refrigerant expands, boils, and evaporates into the evaporator coils, and it becomes a cold, low-pressure gas. This cold gas flows through the evaporator coils, which allows the gas to absorb heat, and by absorbing that heat; it cools down the air flowing past the coils. The fan inside the freezer’s compartment circulates the air to keep the temperature uniform and constant. Because the evaporator coils are so cold, they cause any humidity in the air to freeze onto the evaporator coils as ice or frost. The refrigerant is then vacuumed back into the compressor where the process is repeated. A thermostat controls the process, helping to keep frozen foods at the desired temperature to maintain freshness.

The fan that is located inside the refrigerator’s freezer compartment ( evaporator fan) circulates the air to keep the temperature uniform and constant. The process is regulated through the use of thermostats which help to keep your foods at a desirable temperature When the temperature is cool enough, the thermostat senses it, and turns the power off to the compressor and fan When it gets too warm again, the same thermostat turns power back on. As the cycle continues the evaporator coil’s will build up with a lot of ice and frost and occasionally will need defrosting.

Most modern refrigerators have an automatic defrost system which includes three major components: the defrost timer, defrost thermostat, and defrost heater.

The defrost timer, approximately every 6 to 12 hours, of compressor run time cuts off the power to the compressor and cooling system, and switches on the defrost cycle. The electric heater is then turned on and will melt the ice and frost from the evaporator coils as the ice melts, it drips through a drain hole, through a tube, and into an evaporation pan down by the condenser coil which aids in the cooling of the condenser coil and where it evaporates . The defrost heater has an electric heating element and is located just beneath the evaporator coils. This heater element gets hot, and due to its proximity to the coils, any ice or frost build-up usually melts pretty fast. The defrost thermostat will turn the heater’s off if the evaporator area gets to warm after a preset defrost time the timer will advance back into a run cycle and start cooling again

How do Washers work?

Most washers work basically on the same principal The information below will help you understand how most washers work. To find the problems with washers, it is important that you have an understanding of how they work.

If you have to do any kind of repair or maintenance on this unit, make sure to unplug it from the power supply.

Washers work by filling with water , agitating , draining the water , then spinning First you load your washer with the clothes you want cleaned. Make sure you don’t pack the clothes in too tightly; you want the wash to be able to circulate within the basket to get them as clean as possible. The controls let you adjust wash settings, such as the water temperatures, water level, spin speeds, timer cycles, etc. When operating properly the washing machine completes the cycle selected on the timer.

There may be more than one selector switch on your washer. One allows you to select your desired settings for load size, and one will let you choose whether you want to use cold, warm, or hot water. The start switch is usually integrated with the timer assembly. When you set the timer to the desired cycle, you either pull out or push in the timer knob to begin the cycle.

Then the cycle will begin ,the timer sends a electrical current to the water level switch witch controls how much water will enter the tub. Then the power go to the water mixing valve allowing water to enter tub . When water level switch is satisfied ( this switch sense’s the water level by pressure ) the motor will engage and depending on the type of washer transmission (the motor will rotate one direction for wash and the opposite way for spin drain) or a solenoid will engage to mechanically change the gearing of the transmission either the agitator will begin to move back and forth or the basket will rotate back an forth ( front loaders ). The timer will wash for the set period of time at the end of wash cycle the water drains from the tub by way of the pump. As the water drain’s from the tub the spin cycle begins threw either mechanical actions in the transmission or by reversing the motor the entire inner basket will begin to spin and by centrifugally extracting the water from the clothes . Then the procedure will continue again for the rinse cycle.

And by the use of switches. Newer models may use an electronic control circuit board. The washing machine will perform it’s actions.

There are certain safety features that are integrated into washing machines. What happens if you lift the lid on your washer? It stops spinning or agitating immediately because the lid switch activates the brake. This is to prevent injury to your arms and hands. There is a brake system built into washers by law because many people have been injured in the past by putting their hands and arms into a spinning wash tub. The brake system operates in much the same way as a car With the lid open, your washer may still fill, but it will not spin or possibly agitate.
