ECM FAN MOTOR
I need to test a G.E. ECM 2 speed condenser fan motor. It's out of a American Standard M# XL1800. What voltage goes to the blue and yellow leads ?
TIA

Hopefully you can distiginguish the high voltage leads. The other leads are 24v

Blue and Yellow - 24v
Brown and Black - 220V
Green - ground
Send me and email with the model number and I will forward the service facts, and info on these ecm motors.

Thanks SKBold,
Yes brown & black are my high voltage leads. 24v for yellow and blue makes sense too.

Thanks rundawg,
My understanding is that these motors are 3 phase DC. The motor control converts the high voltage. Are the low voltage leads for the speeds with blue being ground. American Standard
Model # TTZ036A100A2
Serial # Z2926591F
Thank again for any info.
P.S.
motor is a GE 5SME39HLHY02
looks like a GE ECM 142

Blue is common.
The low voltage leads send the signal to the motors module telling it what speed to operate at.
