    Does anyone know the Ohm ratings on a GE Variable speed blower motor.

    Carriers tech support in my area are in a meeting all day and contacting GE directly does no good. Any assistance would be apprecaited.

    Resistance varies with temperature. All readings between windings should be equal. Infinite resistance from winding to unpainted casing. Do not measure resistance through the module.

    Thanks. The reason I am asking is because I have one that runs fine at first and the amps keep creeping up till is shuts down.(1 hr)the bearings are good. I was just looking for a baseline for the ohm rating. When I take the ohm readings R-Bl 5.1 R-Gr vary 4.3-5.9 Gr-Bl 4.6-5.6 Inf to ground, I know its not what is should be. I Just like to know a little extra when something isn't working right.

    Bad stator. Change it. There should be no variance and they should be within 0.1 Ohms of each other.

    I've never seen a temperature-resistance chart for the stator. I just know that they should be equal with no variance.
