The following has also been posted in the HVAC Forum so if I am breaking Forum rules please advise and I will remove one.

A company was replacing a HVAC system near me recently and I was able to harvest the Squirrel Cage fan which they said was still good. I want to wire it to use as a patio "fan" to simply move air when the temp is hot. The fan has 2 brown wires and 1 each red,blue, black, orange and white. I am assuming the fan is 110 volt ac. Which three wires should I use for power?

Thanks

There should be a wiring diagram on the motor. Upload a pic of it. If not, what’s the model number on it?

First you need a run capacitor for the brown wire connections. Then black and white will normally give you top fan speed. The run cap value should be printed on the motor spec tag. It can vary from 7.5 to 15 MFD @ 370 volts, depending on motor size. The typical 1/5 hp motor will use the 7.5 MFD capacitor.

Nut off all unused wires separately... if they short together, it will fry the motor windings.
