    Furnace Blower Motor
    I am replacing my blower motor. My question is when replacing it do I have to get exactly what the label has on it because I'm having trouble finding the exact numbers online? I am looking for 4HP, 115V, 60HZ, 6.3A, 1050/850RPM. It was made by Franklin Electric unfortunately it looks like they do not carry them anymore. Is there any number I can be flexible on as long as I am pretty close?

    Thanks,

    Nate

    The only number that isn't too important is 6.3A. You need 115v because that's what you have as a supply voltage. The RPM is important because it determines your volume of air. I'd stay close or on the money with the HP too. You should be able to get a motor on line without too much difficulty. Try this site for more info toad.net/~jsmeenen/motor.html

    Thanks that site is very informative. I have another question on the label it lists 4hp. Does that mean 4 horsepower? The highest I am finding is 1hp, 3/4, 1/2 and below?

    4 hp does mean 4 horsepower and that does not sound correct for a blower. Any chance a number has worn off, could it have been 1/4 and now only the 4 remains.

    Yeah, that 4 HP sounded suspecious to me. A 4 HP motor would draw a lot more 6.3 amps.

    I looked at it again and it does list 4hp. I don't think a number is missing because the label is in very good shape. I wish I could send a picture because I took one. Well I am debating whether to have a new furnace installed--bye bye income tax check.

    A new furnace will cost a lot more than having a pro replace your motor. Pro will have no difficulty installing the correct unit for your application. Good luck

    Thanks for the advise. I'm not getting a new furnace because of the motor I am getting a new furnace because it is way past its life expectancy and it needs a new motor. I know getting the motor replaced is well below the price of getting a new furnace but if I pay for a new motor and the furnace still goes out this winter I'll really be upset. I only entertained the idea of getting a new motor if I could find one under $150 and I could replace it myself.
