Blower motor Question
The blower motor in my 1993 Lennox split unit went bad. It would work for a short time and then quit. I opened unit and found the squirrel fan not moving. I tried to "jump start" motor by hand thinking maybe a faulty capacitor. However it would not move. It was humming and very hot. I disconnected power and the motor would spin freely. I assume the motor itself is faulty. I have searched the web for a few days now trying to find a replacement motor.. I cannot find one that matches my numbers exactly. it is a GE motor and I think that it is a manufacterer specific number, I am aware of the frame number and found several that are similiar and look the same, I went to local hvac supply house and they would not help and I even carried the motor in with me,. below is the information that i have. I am hoping someone can give me a drop in replacement part number or point me in the right direction.
lennox gas heat/air unit
The following numbers are from the motor itself.
5kcp39gg n953 s
stamped on frame is n953vhv
any help would be greatly appreciated.

i want to add I have found out that this is a 48y frame. So can I just get any motor that is within the same specs and wire in myself. appears most motors have two capacitor wires, power wire and the rest of the wires are for motor speed.

It's most likely a capacitor run motor and not a capacitor start. It still could be a bad capacitor. Maybe check e-bay if you find that you need a motor.

Are there any other specs on the motor? HP, RPM, Voltage, etc?
This may help narrow the search a bit.

A web search for that motor shows a 1/3 HP, 230V 3 speed motor, 1075 RPM.
Based on that, found this item, that should work, if that info is correct:
PSC Motor #G1929961

Price is not bad, and free shipping as well.

You should also replace the capacitor at the same time. They list the suggested cap.
