I have a desk fan, it broke, when i opened it i saw a component put in between the live wire and a switch mechanism, i have connected the two wires that was connected to the device and it works fine, i am just concerned about the effects that this change will have later on.
A description of the component follows: It is round steel cylinder with a coper strip on the outside, on the copper strip lays two copper connectors that is pressed to the cylinder which is connected to the wires that goes to live and the switching mechanism in turn.

Re: Desk fan broken due to melted component
I believe what youre describing is a thermal fuse.
Normal fuses (like the one in the plug) protect against too much current being drawn by a faulty device, which is the most common type of fault.
Thermal fuses protect against the temperature within an enclosure going above a certain level, which can occour even though the current being drawn by the device is within the rating of the normal fuse.
Thermal fuses are an additional level of protection for the user of a device that has a tendancy to overheat without drawing enough current to blow the normal fuse. They also provide protection to the device itself where overheating may be caused by a condition outside it's normal operating envelope such as something has jammed the fan blades. Most fans use shaded pole motors, a type of motor that when stalled (jammed) doesnt draw excessive curent but does overheat.
It's your call as to whether you continue to use it without repalcing the thermal fuse, but so long as you dont leave it unattended, I doubt it will be a problem.

probably not the reason for the dim light. It probably has more to do with the installation where you have wired the light before or after the fan so that power so the bulb is reduced by the resistance in the fan.
lights and fans are wired in parallel so that one doesn't affect the other
Might pay to talk with an electrician on the issue
There is a limit on the size of the bulb that can be used and a 100 watt halogen bulb will probably melt the surrounds and set fire to the fitting

Are you sure the button is working? If you're savvy enough, and since you've been able to test the other components, take the button apart and hot wire that computer by tapping the wires together. It's worked for me in the past.
We would strongly advise against dismantling your Dyson Air Multiplier desk fan any further than is shown in the User guide, as this could cause damage to the internal component and electronics. Additionally, it can also void your Dyson warranty if this is currently valid.

Question about Brookstone Desk Fans: Slim Personal Desk Fan Open Question
I took mine apart by removing the small screws that hold it together. my top fan cage was broken and loose. I glued it back together and the next day I just reassembled it and it works fine.. just look at what you are doing and dont FORCE anything common sense should allow you to do this... I am a retired auto mechanic 80+ years old and it did not give me any trouble until the e-clip jumped off, but I found it and all is well.. the screws are shiny and the case is black, so take them all out and lay in a pattern so you can reverse the pieces for reassembly..
Let's figure this out. Broken or otherwise disconnected wires usually cause an open circuit preventing adequate current to a componant. Two wire switches act as light switches do. they either close or open a circuit.In this case, the warning lamp or fan relay is ativated when the temp rises. Cold, the circuit is open/ broken preventing any controlled componant from activating.
First check for any power/voltageat the disconnected wire and the connected wire. Which ever wire that is powered is the supply wire. The one without is your controlled componant wire. Touch the two wires together, bypassing the switch. The fan should come on and turn off when disconnected again. Ignition switch needs to be on.Because of the load the fan pulls, a relay is between the fan and switch.
The switch closes powering the relay, then relay close contacts closing a secondary circuit which in turn permits power to the fan. The fan circuit is powered by the battery and controlled only by the relay.
Yuup, two circuits. Switching and fan drive circuits. Yes, Hook the wire back onto the switch after testing as outlined here. Good Luck and remember to always verify power (fusec ondition). _Ned_
If thisis two fans, the first one check the starter capacitor to the motor. it canbe weak or defective or the coil winding of the motor is open. check the switched power tothe coils.
The second motor can get hot due to friction or loose bush/bearings or faulty capacitors or faulty windings.you must check all these one by one.

i have 1 as well and it broke too. this is http://computers.pricegrabber.com/laptop-accessories/m/1754767/
if its the cord's thats broken, its most likely the switch, more specifically the soldering where the wire connects to the switch is prolly broken. i just sawed my switch open w/ a knife, and took a look. now if a wire is loose in the switch, u can either solder it back on, or (in my case i always have the fan on anyway cuz of my **** dell computer overheating) rip the wire off the switch completely and just connected it w/ aluminum foil.
