    Bryant Furnace problems
    Hello everyone, I have a Bryant 80v furnace. Everything works fine till it is time for the blower fan to come on. I have opened it up, and the fan wheel turns freely. Checked the fuse on the circuit board no problems there. I been doing some reading about it all day long. The furance lights and ignites, and runs with the furnace fan for a few minutes, after I think about 5 minutes it must time out because the blower motor is not coming on. I believe I am getting error code #33 on the circuit board. Any suggestions?

    Will the blower motor run if you turn the fan switch to on at the thermostat? If it will check to make sure you have a good connection on the wire marked heat on the control board on the furnace.

    No it does not. Fan does not come on no matter what I do. Times out after about 5 minutes of the furance fan running, and getting up to tempture.

    The only thing to do now is to see if you have voltage going to the blower motor. Its prosses of elimination. If the blower is not getting voltage it's the control board if it is it's the blower motor or run capacitor bad.

    Okay... I am not very experienced with using a meter. But I do have one. How would I check? Is there a webiste that has pictures someplace on how to do it? Id the control panel was bad, would the furance still fire up, and ignite? Going to have to figure it out quick... getting chilly... :(

    Okay I did some reading, and more reading. Went out to radioshack and picked up a meter. I tested the connection going to the motor and there is 120 volts there. There is 120 volts there all the time far as I can tell. Where is the run capacitor located?

    I did quite a bit of looking there, and don't see what part this is. I will post a picture of it. But it does the same with or without thisd piece hooked up. The furance goes through all the ignition lighting, and it burns for awhile, then it quits because the blower does not come on. There is voltage at the termnals to the motor... anything else I can check besides the motor itself?

    You may have a bad motor capacitor , it's a cheap part about $5 and worth a try , you can purchase it at any a/c supply house.Good luck ,Mike
    P.S. your picture is of a transformer and supplys the control voltage.

    Where is this part located at? Is it inside the motor itself? Thanks for your valuable input.

    It will be at the end of a wire from the motor. There are pictures of capacitors in the sticky.

    I agree your picture looks like the 24 volts AC transformer. It looks like it says 12ADC. If it has a third secondary lead, perhaps it could be rectified to 12 amps DC.

    The capacitor is usually mounted on the blower housing, it is a oval shaped metal part with two wires attached.

    If you are getting voltage but the blower motor is not coming on then I would check the capacitor first. If it is reading within range then I would check the motor's amp draw. If the cap is bad or the motor winding has failed the unit will over amp. Most motors are thermally protected and will actually open up the thermal overload. If the capacitor is OK I would simply switch the blower to another speed.

    I have looked on the housing, and I can't find anything like you describe. Is it possible it doesn't have one?

    Can't seem to find the capacitor on this. I have looked on the housing, and there is nothing there. Could it be mounted someplace else?
