hello all I have the tool to easily open the case in this CW 80 and have a replacement cooling fan but the seller provided no particular way to remove the circuit board to gain access to the factory fan circuit the seller says add it without removing the existing so where do you power it from and or how do you get the fragile circuit board out? any input appreciated
Clip the leads on the old one and splice them to the new one.
thanks for the reply John but I almost cannot even see the fan wire leads to disconnect and splice to another fan
Remove the handle and potentiometer. This allows access to both screws holding the circuit board on. Remove the circuit board. Then you will have full access to the fan wires.
thanks much but I did all that and it seems something is still holding this board back
Sometimes boards stick to standoffs just like plastic.
Is this some kinda really thin or ultra brittle board? A small sharp rap near the holes, on an edge, or a careful pry would loosen every board I've ever come across. They can be brittle, but not usually THAT brittle. And if traces are intact, you can glue and/or back it up if cracked. Traces and components are all that really matters really.
You have to work a bit to crack a fiberglass PCB.
