My furnace blower motor burned out. It's a 240 volt 1/3hp 1050rpm 4speed 3.1amp 60hz single phase motor. All the replacement motors I can find, including from the manufacturer, only have 4 wires. The original has 5 wires. Is it possible to wire the new motor up and how? Can I splice the two 120volt legs and run it into the 240 leg? I really need an answer. My Mom is 83 and lives with me and the heat index here is the 100's. We are desperate because a repairman will charge us untold money and we are both disabled and lived on fixed incomes. If you can help, please reply your soonest.
