Preston Microforce Knobpot


Recommended Posts

Hi all,

 

Do any of you have experience with the older Microforce v+f? Mine has the old style knobpot from bourns with the "clockface readout". The arms on the dial stopped working. Have you ever been able to fix one of these yourself?

 

Thanks,

 

Andre

I haven't worked on one for about 15 years, but from memory it's a sealed unit. You might be able to pry the window off and see if you can access the arms but I suspect your best bet is simply to replace the whole knobpot. That's what I used to do if one stopped working.
