Tip & How-To about Cfm 802 Ecofan Table

Clean the device

I used an air compresser at 50 psi to blow the dust out of the crevases and then through the back of the fan motor to return the 2 year old unit to like new operating condition.
Hold the blade while doing this so you do not over spin the fan.

I suspect the dust in the motor was sapping the low voltage electricity being generated by the device. House dust buildup causes faults in circuit boards p. Carbon will cause arcing; soot is pure carbon,

Try this before a rebuild.

Cheers,

Mike

aspire 5742 i3-370m overheating how do i fix it


Three things that will make a laptop overheat:

1. Dust - Dust inside the laptop, dust clogging the vents, dust around the fans, dust around the cpu and heatsink. To fix it, take the laptop apart, take a can of compressed air and blow out the dust.

2. A fan is not working. To fix it, you will have to take the laptop apart to replace the fan.

3. The Thermal Paste around the cpu and heatsink has dried up or is too thin to keep the unit cool. To fix, take the laptop apart and apply a fresh coat of Thermal Paste.

Another work around for a laptop that is overheating is to by a Laptop Cooling Pad that has fans on it and it plugs into the usb port of the laptop. The laptop sits on it and it keep the laptop cool. You can buy a laptop cooling pad for less than $20 from Tiger Direct.

When the site opens just type Laptop Cooling Pad in the search box at the top of the screen then press GO. Sort the returned results by Price Low to High.

This sounds like a thermal issue, meaning after the receiver has been on for a while it gets to warm and then fails. I suspect after 8 years the unit may have accumulated some dust that is not allowing the heat sinks to dissipate heat adequately. I would use compressed air and blow the unit out. Some computer stores have blow stuff in a can that work well. If you have and air compressor, dial it back to 10 psi or so. You will be amazed at how much dust will come out of that unit so you may want to unhook the unit and take it outside. Also be careful not to stack anything on top of your receiver. Make sure there are lots of openings around the unit. High temperatures kill electronics.
Hope this helps.

how to open tower fan to clean it


Use compressed air to blow the dust etc. out of the unit.  You can purchase a  can of compressed air from Home Depot or Lowes, or Google "compressed air in a can."  Just make sure you clean the unit outside to keep the dust etc. out of your home.

I have the answer for the fan issue on the KDSR50XBR1!!!!!

Ok, I think I have the answer for the BIG FAN failure. I recently did a similar fix on the spindle of an xbox 360 and it is identicle. Ok, this is an EXTREMELY EASY FIX...

Open the back of the tv, locate the large fan (on the lower left on the back of the set.) unscrew the screen and remove the fan.

Once the fan is removed, you will see the side with the model number and the other side is totally open.

On the open side, pull...

The fan will come off, into your hand, it is only held by magnets...

You will notice a spindle on the fan and the other side has the magnets and the hole where the spindle came from (this is the fan motor).

Clean both the spindle and the hole (motor) with a q-tip. The hole is smaller than the q-tip, but do the best you can to remove the old lubricant.

Get a bit of WD40 and lubricate the spindle and spray a touch in the hole.

Put them together, reconnect your fan, test it on startup and thank me...lol...

HOPE THIS HELPS!!!! IT WORKS, TRUST ME...

What do you think? Spread the word, lets save some folks from spending needlessly...
