Question
Good afternoon,
I purchased this motor to replace an old westinghouse hole house attic fan, the old motor is common sense wiring red low, white common,black high-speed, which is what comes from the switch.the new motor only has 2 connections 1 yellow & 1 blue which I assume are where the black & red connect but no place for the neutral white . There was no wiring instructions with the motor.
I hope you can direct me in the right direction.
Rob

Answer
This motor is only 115V so the incoming power wires should be black for hot and white neutral.

On the new motor the connect it the same way. usually black and red power leads are 230Volts. use a voltmeter to measure the voltage coming in.
green should be ground anywhere on the motor frame.
