Just got a Monaco Spa from a friend. Blower works, blower sw/circuit does not. Couple of components on p/c board are blown. I think it's the blower circuit, since everything else works.
I want to run a new 240v circuit off of the power, for the blower, and wire in a w/p switch. I have heard reference to an 'air-switch'. Is this what I need?

Any ideas/recomendations?

You could use a double pole air switch to control the blower. Most likely the
$2.30 triac is what fried on the circuit board. They usualy fry when the blower overloads, so you might want to be aware of a possible problem with the blower even still.
