Perfect. I am doing exactly that. It only
makes sense, less components, same
function and easy.
Here's the component and at the bottom,
the mounting fixture:
I'm bypassing the wiper and selecting the
maximum and minimum speeds. To try that
out I connected a 12V DC thermostat
bypassing the wiper. I set it for 120F
(49C), the same as the Thermal switch has
and gave it a run.
The result: Far better than High speed's
volume level and it works perfectly as far
as I can tell. I should have done this
Thanks for the suggestion!
