Blower motor replacement help, please!
Hey all, I am new here but can't seem to find exactly what we wanted in the searches, so I'll post. Our old HVAC blower motor (the one inside our furnace, not outside) has gone out on us, and we just bought a replacement for it. The old motor is a Friedrich 5KCP39KG that is 1/3 horse and 4 speed. The replacement motor is an AO Smith DL1036 that is 1/3 horse and 3 speed. When we got the unit, the supply technician said that we would not wire the orange wire because it has one less speed than our old one. Hubby hooked it all up, matching colors to colors like the service technician said. Fired it up, and within 10 minutes, the unit smelled hot and shut itself off. Did it again later, same result. There is a yellow wire that also appears to be extra on the new unit that he hooked up to the capacitor, and we're wondering if that could be the problem. (The cap is new, by the way). Any help will GREATLY be appreciated! Thank you so much! You might peak at this http://www.aosmithmotors.com/concert...1036drawCat=A Also match it up to the Friedrich wiring diagram, if you don't have it you can get it from Friedrich.com Yellow does not go to the capacitor. Here is the motor wiring schematic that is pasted on the inside of my unit. My husband says if the yellow line isn't connected to the capacitor, the motor doesn't run. He says looking at the diagrams (and thank you SO much, BTW), they all appear to be correctly wired except the yellow. Should he splice the yellow into the white (listed as Comm on the Friedrich schematic) and plug THAT into the cap? http://www.geocities.com/stormwarnfm...hschematic.jpg There is no yellow on the diagram you provided. So what is it? What is the Friedrich Unit model and serial number? Not what you posted from the motor (that was a GE number). Hmm...good eye. Here's the direct scan from the old motor. It IS a GE, BTW...my apologies for thinking it was Friedrich...the unit is, but apparently not the motor itself. http://www.geocities.com/stormwarnfm/gemotor.jpg ETA: The first picture is what was pasted on the inside of the Friedrich panel itself...not the motor, and it does, now that I've looked, indicate a GE motor. This picture above is off the motor itself (the OLD motor never had a yellow line, just the new motor)...neither of which list a yellow line.

Not what you posted from the motor (that was a GE number). Ok, from what I can see which ever lead is 115 to ground (common) goes to yellow. Neutral is used to excite the speed windings high, med, low. Wish you had posted friedrich info, be nice to check the unit diagram. http://www.friedrich.com/support/index.html Where would I check to find the information? The unit is quite old...I would wager at least 20 years. I've looked, but obviously, this isn't my line of work and I'm bound to be overlooking it.

Originally Posted by Jarredsdad Wish you had posted friedrich info, be nice to check the unit diagram. Ma'am could you in anyway explain which part of What are the Friedrich Model and Serial Numbers you are having such great difficulty understanding? I asked you where I could locate that information in my previous response because the unit is over 20 years old and I can't find the information anywhere on it, therefore, I would think it would be completely understandable that I haven't been able to provide you with it if I can't even find it! Not everyone is a professional that knows where to look for the information you asked for...please try to remember that in the future. That aside, thank you SO MUCH for your assistance, because your previous response (quote: Ok, from what I can see which ever lead is 115 to ground (common) goes to yellow. ) just fixed our situation. The motor has been running over an hour without any sign of overheat, whereas previously, it was running only 10 minutes before self shutting down. I am disappointed at the attitude I received in your last response...I don't appreciate you making me sound like an idiot...but you have saved the day again (by what I see in your history helping other folks here), so perhaps you just didn't catch my response explaining I couldn't find the information before you wrote your reply...so I'll just assume that was the reason for the response given (and I agree, I'd be frustrated too had I NOT explained I couldn't find it). If you still want me to supply the information, just tell me where to look...I've looked all over the unit and cannot find anything other than what I have posted to this thread, which is not what you want...because that is motor specific. Originally Posted by Jarredsdad Ma'am could you in anyway explain which part of What are the Friedrich Model and Serial Numbers you are having such great difficulty understanding? If it's still there, you should see a plate or sticker that has the model and serial number on it. Along with voltage, current, breaker size and other info. If the electric enclosure is removed the info may also be in there or duplicated there. The wiring info I provided was an educated guess, which I would rather not do if avoidable as I like to deal with facts. I did not mean to offend in my last post but when we ask for model and serial the person asking has a reason as they most likely can obtain the original manufacturer literature. While your literature may not be on the Friedrich web site, I know the warranty manager very well. Meaning if it exists I can get every page of literature that originally came with that unit and provide it to you. I in no way ment to make you feel like an idiot. I did not see anything in your posts indicating you could not find the model and serial. I just kept thinking the tag is right there, what are the numbers? And, come to think of it your are correct that your post about finding the numbers did post while I was making my last post. I started it, left, came back, etc.. before submitting. I, we, don't come here to make fun of people or make them feel less of themselves. We all stumbled on this site and found we can help people do things for themselves that would otherwise cost thousands of dollars in some cases. Again, I apologize Ma'am, I did not mean to insult you intellegence. Am I forgiven? Find the numbers, I'll get you the literature. Of course you're forgiven...I don't hold grudges...blame me being insulted on the woman in me. I completely understood why you were asking me for it...I just do not see it anywhere. The only sticker I am seeing is the one I copied that had the motor specs. After the house cools down (we've been living with a window a/c for the last 2 months waiting on a serviceman to be available, so that's why we finally went the DIY route) I'll have hubby shut it off and we'll see if that sticker has the rest of the information you are asking. As of right now though, the house has gone down from 87.6є to 82є...YAY!

If your happy, I'm happy.
