Furnace Blower Makes Humming Sounds at Low Speeds

Question

When my house is warm enough so that my furnace runs at one of the lower speeds and the burner isn’t on, the blower motor makes a humming noise and seems to slow to a crawl. Might the problem be a bad capacitor, or what else could be the problem?
