Blower motor help

Hey everyone,

I am pretty handy, but have never worked on a furnace so I am seeking assistance and knowledge.

I have a pretty old furnace and I am having difficulty with the blower motor. The motor will not turn on. It makes a humming noise and heats up when it is turned on. So by this it tells me the unit is getting power but is defective. Is that right?

Secondly, if I am going to replace it, where can I go to replace just the motor. It is a GE model # 3J522GXG 115v, 5.2a, 1/4HP, 1725 RPM. But I believe it was discontinued. Also to note this motor works on a belt system and is seperated from the main blower unlike most others I have seen.

Any suggestions or thoughts are greatly appreciated.

Residential belt drive motors aren't PSC motors so they don't have a capacitor.

But good thinking in general though. I hate making 2 trips to a supply house.

I have two motors available to me now.
115 Volt, 5.6 Amp, 1725 RPM, 1/3 HorsePower for $50 (NEW)
115 Volt, 5.4 Amp, 1725 RPM, 1/4 HorsePower for $25 (USED)

My only concerns I had was my previous motor was 1/4HP and 5.2 amps. Thank you Kenmac for the HP question. I assume a 0.2 or a 0.4 amp difference is not a big deal aswell.
