"Jdhawk6" hasn’t been on this forum for almost 7 years. He posted this thread in Jan. 2013, so I doubt you will get a response back from him as to the outcome of this problem.

Hi jdhawk6,

If you have a way to test in a working furnace measure the voltages on the control pins. That will get you in the right direction. Some motors use a varying DC voltage 0-5v to control the speed. As others have said good luck getting the exact info from Carrier, it's most likely proprietary.

o.k., you only have 6 post-they are all right here and you are wanting some details that are NOT going to delved into in an open forum.

might want to get that post count up or maybe start a thread in the introduction forum indicating any experience you have pertaining to the question you are asking.

oh, if you are in this industry, you may want to contact your carrier rep, they probably have the info you want, too.

About all I can tell you is that it is low voltage.

Carrier probably has that info locked up as proprietary.

this is just the motor portion of the inducer, you can see the plug.

Carrier 58MVB080 2-stage. It has an ECM blower and inducer with a 2 stage gas valve.

I have never seen an IDM with an 12 pin molex plug, what did this motor come off of?

I'm sorry it's a 12 pin connector, not an 8 pin.

Unsure. The motor has an 8 pin molex connector on it. Unsure if they were/are all used. I have only the motor on me at this time. Would like to figure out a way to be able to run it on the bench and control the command voltage to be able to adjust the motor RPM manually if possible. Will be used in a classroom setting.

how many wires and what colors are they?
