    Blower not working
    I have a Carrier Weathermaker 8000 furnace and recently the blower does not run. I noticed that when I set the Thermostat from AUTO to Run the Fan does not come on a faint click can be heard.

    What is the best way to troubleshoot this issue?

    I suspect the issue is with the cirucit board or blower motor.

    Does anyone know how I can manually test the blower motor?

    Thanks

    If you set the tstat on fan instead of automatic does the blower work then?

    The blower does not work regadless if the thermastate is set to Heat, Cool, and the fan is set to Auto or RUN. I do hear a click when FAN is set to RUN.

    Is a chance you might just need a capiciter for the fan motor,for a guess it's the cheapest way to go, most are attached to the blower housing itself,and only cost a few bucks. Be sure to take old one loose or with you to get an exact match

    Do you know of any test that I can perform on the Motor Run Capacitor? Some of the research that I've done points to the circuit board. Is there a way to jumper around the circuit board to force the Blower ON, just for testing purposes.

    Thanks
