How to… Replace the Cooling Fan

Postby The Jolly Good Framer #1 » Fri Aug 21, 2009 11:09 am

Well, when I say ‘How To’ its more of a ‘What I Did’
How I replaced my noisy/dead cooling fan.

Ok, so the cooling fan in the control box of my Valiani mat pro was getting very noisy. But when it started to sound like a small diesel engine I thought it was time for a new one.

The tools I used were a posi-drive screwdriver and 7mm spanner or a small adjustable spanner. (I also used a soldering iron and a pair of pliers but that was for a little extra that I will explain about later)

I got a new cooling fan from an internet retailer for £12.47 (inc del and VAT)
The fan needs to be a 240v 120mm

First of all I switched everything off and unplugged the control box from the mains (safety first!) and opened the control box door. The cooling fan is attached to the inside of the door.

At the bottom left corner of the fan I unplugged the two spade connectors that supply the power to the fan. (I made a note of which connector went where)

Next I took off the vent cover and the filter from the front of the door (I also took the opportunity to give the filter a clean!)
This then revels the heads of the 4 bolts that fixes the fan to the door. I undid the nuts/bolts and the fan came off.

I then took off the finger guard from the old fan and fitted it to the new fan and then bolted the new fan to the door.
Last of all I plugged the power spade connectors back in place and replaced the filter and vent cover.
I closed the door and powered up… aaaahhhh sooooo quiet!

Job done. :clap:

Now, the business with the soldering iron. The fan that I got didn't have the spade connectors already fitted – it just had two loose wires.
So all I did was take the spade connectors off the old fan and solder the two wires from the new fan to it.
So its worth finding a fan that has the spade connectors already fitted. You can get them.

Just as a quick disclaimer – If you use this information as a guide to replace your fan and it all goes wrong please don’t blame me!

Fan from Maplin fits and has the correct spade fitting. You can buy them from Maplin on line for about £15. I can send you one for £70 and still undercut the most obvious way of getting one.

Just out of interest what is the wattage of the fan, I've often wondered what the power consumption of the cutter is when the machine is idle.

Thanks Keith

From the specs that I have the cooling fan is rated at 0.18 Amps.

does that help ?

If the machine is sitting idle for any length of time. Then just use the 'Emergency' Stop button to put the system into Standby mode. You are not using any electricity then.
