Dryer

Dryer
DRYER

A clothes dryer, drying machine, or dryer is a household appliance that is used to dry and remove moisture from loads of laundry and textiles, usually shortly after they are cleaned and washed in a washer, or washing machine.

Most dryers consist of a rotating drum called a “tumbler”. Heated air is circulated through the rotating tumbler to evaporate the moisture. As the tumbler rotates, even distribution of air space is applied to the articles. The dryer can cause clothes to shrink, and/or become less soft as a result of a loss of fibers/lint.

Moisture and lint are created as a result of the tumble drying process, and are pulled from the drum by a fan motor and then pushed through the remaining exhaust conduit to the exterior termination fitting. A clean and clear dryer vent improves the efficiency and overall safety of the dryer. If the dryer duct pipe becomes partially obstructed and builds up with lint, drying time increases and causes the dryer to overheat and waste energy. In extreme cases, a blocked vent can potentially cause a fire.

Dryers are one of the most common household utilities that need servicing, call F&A Appliance Repair today to resolve any issues you may have!

 

Washer

Washer
WASHER

A washer, or washing machine,  is a household machine used to wash loads of laundry, such as clothing or other textiles. A washing machine primarily uses water to wash clothing, as opposed to dry cleaning or ultrasonic cleaners. Washers generally use a combination of laundry detergents and hot or cold water to allow for different types of stains and soils to be cleaned from the clothes.

Most washers consist of a smaller inner drum, larger outer drum, paddles, and an agitator. Washers consist of three components of a wash cycle: The wash, rinse, and spin. During the wash cycle, Hot and cold water enter through pipes near the top, passing through the detergent tray and flushing the detergent into the machine. Then, a large plastic agitator turns around, moving your clothes through the water to create an even dispersion of detergent and water. Once in the rinse cycle, the machine dispenses of the dirty water and soap, and then releases clean water while the drum rotates to rinse the articles. Finally, during the spin cycle, the washer’s inner drum rotates at an extremely fast speed to remove an excess water, and moisture.

Washers need proper attention and maintenance to insure longevity and efficiency. Contact F&A Appliance Repair today with your repair needs!

 

 

Range

Range
RANGE

Cook tops and ranges, in their most basic form, are normally easy devices to use and maintain. Their main purpose is to provide varied amounts of controlled heat in specific places to cook food in the most efficient manner.The standard cook top, or range, consists of large heating elements, which are actually resistor wires that can generate substantial amounts of heat. The wire is most often nichrome wire encased in ceramic insulation with a steal sheath surrounding the ceramic.

Each cook top or range surface unit (burner) may contain 2 or 3 different elements with varying resistance ratings, mounted together. The surface units may be wired directly using terminals located at the end of the surface coil, or more commonly, be plugged into receptacles mounted under the range/cook top cover. This second type of mounting makes for easy cleaning access, but it increases the risk of burned connections.

In order to control heating temperatures, each heating unit will usually contain an infinite switch, which provides a number of heat settings using a system of heat and tension on bimetal switches. A less common temperature control is the fixed-temperature switch, which has the ability to control the heating of the elements to fixed temperatures. Push buttons or rotary dials allow for cooking temperatures to pre-defined levels which may include low, medium or high. Heat levels are established by applying different voltage levels to various coils with varying resistance levels.

Refrigerator

REFRIGERATOR

A refrigerator is a common household appliance used to store and conserve food and goods for everyday consumption. In the refrigeration cycle, there are five basic components: fluid refrigerant; a compressor, which controls the flow of refrigerant; the condenser coils (on the outside of the fridge); the evaporator coils (on the inside of the fridge); and something called an expansion device.

The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator.  When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. Now in liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge.  The refrigerant absorbs the heat inside the fridge, cooling down the air.  Last, the refrigerant evaporates to a gas, then flows back to the compressor, where the cycle starts all over. This allows for a controlled environment to store foods and products to be preserved, and remain fresh over a longer period of time.

Freezer

FREEZER

Your freezer has a compressor and a closed system of tubing that contains a gas (the refrigerant). The compressor pumps the refrigerant and compresses it. The refrigerant flows through the coils on the back or under the freezer and through an expansion valve to the inside of the freezer. As the refrigerant passes through the expansion valve the pressure drops and so does temperature.

Inside the freezer a fan circulates air over the chilled tubing and the refrigerant absorbs the heat from the freezer’s relatively warmer air. If you prefer to just think of the fan blowing cold air into the freezer, that’s fine, it all works out to pretty much the same results. But technically, the heat is being pumped out rather than the cold being pumped in.

If the temperature outside a refrigerator or freezer, is too low, the appliance will not cool efficiently. The appliance relies on there being warmer temperatures outside the appliance for the process to work. So if you keep a refrigerator or freezer in the garage and you are experiencing cold weather, your appliance will probably be too warm.

As the air in the freezer cools, the water in the air (humidity) condenses. Water that condenses in the freezer will freeze into frost. Most modern freezers have an automatic defroster which melts the build up of frost. The defroster is simply a heating element that is controlled by a defrost timer and a thermostat. The water from the melted frost drains out of the freezer into a pan beneath the freezer and evaporates. Another thermostat activates the compressor whenever the temperature rises above a certain level. The level varies based upon the setting of the temperature control.

Oven

OVEN

Today’s ovens come in two basic types: electric or gas. An electric oven uses large coiled wires inside that heat up in order to cook the food. There are two sets of these coils, one on the top and one on the bottom. These heating element heat up when electricity is sent to them. The bottom coil of wires is the one that cooks the food when you bake. The dial on the oven controls an internal thermostat. When you turn it to set the temperature, a copper wire that leads to the cooking area is alerted to the temperature that you want. This wire serves as the temperature gauge, and it sends signals to the thermostat to turn on and off based on the temperature inside the oven. The top heating coil is the broiler. This coil will heat to high temperatures very quickly. It does not have a temperature control like the coil on the bottom. It will heat to its highest possible temperature and stay there until you turn it off.

A gas oven works in a similar fashion, but uses a flame instead of an electric coil to heat the food. The bottom of the oven has a burner that is activated when the temperature knob is turned. It also has a copper wire that serves as the temperature gauge. When the desired temperature is reached, the burner shuts off. When the temperature begins to dip, it turns the flame on again. The flame is fueled by LPG gas and is ignited by an internal lighter as soon as the gas begins to mix with air. Most gas ovens also have a flame at the top of the cooking area that serves as a broiler.

Most modern ovens are self-cleaning ovens. When the self-cleaning feature is used, the thermostat on the oven heats both the broiler and the baking heating elements as high as possible. This chars any debris that is in the oven, and after several hours the oven shuts off and the charred ash can be removed. The oven will have a lock that must be set to use this feature, as the internal temperatures get dangerously high while it is cleaning.
