Furnace blowers have 2 fail conditions: 1) it will not run at all, test by hooking directly to power, 2) the run capacitor is bad and the blower runs slow.

Almost bought a new blower motor because the HVAC "pro" told me it was bad. My motor has 4 wires (3 for different speeds). I connected the white to white and (red, blue, yellow) and proved him wrong!! Thanks for the tip! add a comment
