Why wont my fisher paykel dryer heat up?
First, I assume that the drum spins OK but there is no heat. Many things can cause this. From the most likely cause to the least likely:
1) An open thermal fuse. This is a small "thermostat" with 2 wires at the middle/top of the heater "box" (a tall narrow box on right in the back of the machine), or a plastic type on the duct close to the blower, depending on the model. You will need to remove the back cover of the machine to see these. Check with an ohm meter after disconnecting one of the leads, or jumper the 2 wires together to see if heater works (don't use this way though, fire hazard... replace the device) If this proves to be the cause of the problem, it would be wise to check all ducts and blower for excessive lint buildup. This will reduce air flow, causing overheating and blown thermal fuses.
2) A burned out heating element. Remove tall box on right, element slides out from the bottom together with the "carrier". Look for broken coil, or check 2 terminals at bottom with ohm meter.
3) Burned wires at connectors. Check for obviously overheated wire terminals at all sensors (thermostats and thermal fuses in back), heater box, main terminals where power cord hooks up, etc.
4) Bad thermostats. There are usually 2 or more. A high limit on heater box, just above terminals on the bottom. 1 or 2 will be on the duct next to the blower. Check these with an ohm meter (or continuity checker). Some have 4 terminals, the extra 2 small terminals are small heaters inside the thermostats which alter it's temperature characteristics. These will usually read around 4000 ohms or so. Check the 2 main largest terminals for continuity.
5) Only getting 110 volts: This is often overlooked, but if for some reason one of the poles feeding the 220 power from the house wiring is open but the other is OK (for example, houses with fuses where only one fuse is blown, or a bad circuit breaker with one pole open). The motor and timer run on 110. If the side of the 220 line that feeds the motor is OK but the other one is open the motor will run but the heater, which needs 220 will not heat. Check for 220 volts between the 2 outer terminals where power cord connects or between the 2 "hot" terminals of the 220 outlet the dryer is plugged into.
6) Bad centrifugal switch in motor. This is what actually turns the heater on, for safety reasons, so the heater cannot come on unless the fan is spinning. Otherwise without air flow past it, the heater would burn out.
There are 2 large gauge (usually red or yellow) wires going to the connector on the motor, these go to the contacts inside the motor that turn the heater on.
What percentage of teens and children have a television or computer set in their bedroom?
According to Dr. David Walsh, founder and president of the National Institute on Media and the Family (www.mediafamily.org), 53% of children and 65% of teens in America have a TV in their bedroom. The institute has found that kids with televisions in their bedrooms watch about 5.5 hours of programming more each week than those who don't.

How did you use a cassette player in the old times?
Answer
First you press eject on the player. This opens the door which you have to put the cassette into. Then (and a safety WARNING is issued here), you insert the tape into the slot provided. Then you push the door closed and press play! A simple but genius invention which had touched many hearts, minds (and throats) along its history.
Answer
It worked the same way a CD player or DVD player works: you put it in and press play, fast forward, rewind, stop, pause, etc. Except, with a cassette player, "rewind" literally meant rewinding the actual tape inside the cassette. The music or video was encoded on one long plastic ribbon that wound around two spools (like spools of thread). When the tape played, it wound itself around the spool on the right, and as the winding tape passed over a certain place, the material on it would be played. When you rewound it, it would rewind itself back around the left spool.

Why are tools and equipment important to an electronic technician?
the right tool for the right job. It is true that if you are inventive you can get along and do what you need to do with almost anything, like Mac Gyver. But is always better to have the appropiate equipment and expertise to accomplish the job properly. Hope that helps.
How do you make a strong electromagnet?
Electromagnets are made by wrapping wire around a conductive rod, so that an electromagnetic field is created when current is passed through the wire.
CAUTION : Do not use 110-120 volt AC power in any science experiments. This represents a dangerous electrical shock hazard. Use low-voltage DC wherever possible.
To make a simple electromagnet ,you can wrap 50 or 100 turns of thin insulated copper wire along the length of an iron nail, forming a neat coil of wire tight along and around the nail. (Leave about 9 inches of wire free at each end of the coil to attach to the power source.)
1. Wrap the insulated wire around the nail, moving down the nail as you go.
2. Fix the coil of wire in place with some sticky tape.
3. Clean off the insulation at the ends of the extra wire, for about 1 inch, exposing the shiny metal inside.
4. Bend the ends into loops and connect to a LOW VOLTAGE direct-current power supply, such as a model train transformer or a D-cell battery pack.
When you hold each end of the coil to the terminals of the power supply, it will send an electric current into the coil around the nail. The current will make the nail magnetic. You should then be able to pick up other nails with your electromagnet. (Doing this for just a few minutes will use up all the electric charge stored inside a battery and it will go dead.)
Experiment by using more or less turns of wire to make the coil around the nail bigger or smaller. The more coils you wrap around the nail the stronger the magnet will get. The larger the voltage of the power source you use, the stronger your electromagnet will get. But don't use more than 15 volts -- it is dangerous because the wire could catch fire or you could receive an electric shock.
Another answer
Making an electromagnet is really quite simple. First you get some wire (22-18 gauge should do just fine). The wire must be insulated. Next, take an iron nail and coil all of the wire around the nail except a small bit on the ends. Strip off the insulation to connect to your power supply. Hook the ends up to some batteries, and presto -- you have a fancy little electromagnet.
Another answer
To make an electromagnet, take an iron rod (fairly small). You'll also need some wire, stripped at the ends. You should then wrap the wire into a coil around the iron rod. The more coils, the stronger the magnet. The two wires should be connected to your power source (a proper scientific powerpack- so you don't electrocute yourself). Turn on the power, then see if it will attract paperclips and other small iron and steel objects.
What battery goes in a fossil blue watch?
I have a Fossil Blue BQ-8774. To remove the watch back cover, I unscrewed the entire cover. There are notches in the back cover, and I used a small screwdriver in one of the notches and tapped it repeatedly, opening the back cover in a counter-clockwise direction. The battery inside was a 373, also known as SR916SW.

Placing it in a jar of uncooked rice which will help draw moisture out of the electronics. Let it sit in there for at least 24 hours, preferably longer.
They are used in loudspeakers to replicate sounds-coil type. they are also used in coiltype antennas in the base of receivers such as old emersons. this was an adveritisng ploy that the radios had(aerial eliminators) and did not need unsightly or visible antennas. we had an old zenith with base coil antenna. Also coils have a variety of applicaitons in tuning and band spread. Any electrical coil is essentially a form of electro-magnet.
There are a few possible causes. If the static changes with engine revs then you have a suppression issue. If the noise is general regardless of whether the engine is running then you need to look at the antenna or the radio itself.
Ignition noise will typically produce a "tic, tic, tic" sound on the radio and is likely to be due to arcing around the HT leads or distibutor.
The alternator can produce a whining noise if the suppressor is bad.
The antenna can perform badly if it is damaged or if its earth connection to the car bodywork does not make a good electrical contact.
If you think it might be your radio try substituting another.
Does a 7200mAh battery last longer than 4400mAh?
mAh stands for milliamp hours and is a partial measure of the energy that can be stored in a battery. It is the standard used for rechargeable batteries but rarely used for non-rechargeable batteries.
The rating is only a partial measure because the voltage affects the total energy stored. For a given mAh rating, the higher the voltage of the battery, the more energy can be stored.
For two batteries that deliver the same voltage, a 7200mAh battery will store more energy than a 4400mAh one. Therefore, the 7200mAh battery should last longer.
There are other factors that affect how long a battery can last. The type of load can have a significant effect on the battery life and the condition of the battery itself.
A photocopier is a common sight in any office environment. The role of the photocopier is to make copies of what you put into it.
How many songs can be stored on an apple iPod?
Apple claims that up to 7,000 tracks can be stored on a 32GB Ipod. This will depend on the length of the track and the quality of the sound, as these things change how big the file is. If the Ipod is also being used to store photos, videos or games, the amount of music will be lower.
Give an example of a dry cell battery and a wet cell battery?
a lemon cell or a vinegar cell are simple one cell wet cell batteries you can male at home. for either you will need a piece of copper foil and a piece of zinc foil to use for the two plates.
lemon cell
- slice lemon in half
- in one half of the lemon insert the copper & zinc foil plates so they don't touch
vinegar cell
- pour vinegar into a small beaker or glass
- hang the copper & zinc foil plates the edge of the beaker or glass so they are in the vinegar but do not touch
try some other liquids in a beaker or glass like the was used for the vinegar cell. the ones that make operating electric cells are called electrolytes. some suggestions are:
- baking soda solution
- salt solution
- sugar solution
- orange juice
- liquid detergent
- hot water
- ice water
- cola
- etc.
if you are using the same beaker/glass and/or plates with different liquids, be sure to wash, rinse, and dry them between experiments.
How do you jam or interfere with ham radio?

How do you relight your hot water heater?
typically there is a pilot light underneath the base of the water heater. There should also be a latch or opening so you can light it. Look inside with a flash light so you get a better view before trying to light it. I recommend using long matches or a barbecue liter.
How does a scrap heap electromagnet work?
An electromagnet can be used a couple of ways. It can be used on the end of a crane, to pick up large pieces of metal to be moved into shredders, or restacked for transportation, crushing, etc. It can also be used to separate metal from non-metal pieces. Usually, these types of magnets are on a conveyor belt, and will cull metal from, say, plastics or other non-ferrous metals such as copper, and aluminum.
How do you dispose of totally broken electrical products?
Most communities now have a few days a year set aside for recycling your electronic products as many contain items that may be considered hazardous to the environment. The recyclers will try to reclaim the gold from some of the circuit boards and properly remove the hazardous contaminants. Most communities set aside a few days every year for the proper disposal of used electronics items, due to the possible contaminants they may contain. If they're recycled, the recyclers would then try to reclaim any gold that's used as well as properly remove the contaminants.
Is it possible to make a robot?
Yes.
In that people can become oblivious to the world around them when they begin to go through their daily routines in an automatic, unfeeling manner.
No.
People cannot become mechanical devices as shown in fiction. The complexity of the human body is far greater than the most intricate machine ever created.
Can you use car subwoofer with your home stereo?
You need to make sure the impedance matches or you will blow you amplifier! It would be best to replace it with the same brand as the speakers, feed it with a digital cable. There won't be a problem of overloading your amplifier.
