Replacing furnace blower motor

[CBHvac]

I think you havea different version of cute... you know whats gonna happen if he hugs me, and God help if his lips pucker up..

Well if it's like the one the other day.......... .........someone put in a 1/3 hp in place of a 3/4 hp motor........Ooops.

And to the OP, call a competent, Licensed, Insured, Trained HVAC Tech to resolve your problem!!

If it was soooooooo easy, you wouldn't be asking all the questions now would you??

Ha. Ha. By this reasoning only professionals should change wheels on cars-- someone might put the wheel on backward and with power the vehicle would just spin around. Seriously, anyone that doesn't know what they are doing, should hire someone who does, but reading a few books can often provide all the knowledge anyone needs. Anyone that doesn't have enough sense to check motor direction before installing, shouldn't. There are damn few thing I can't do or fix around my house and I'll do it better and a lot cheaper than a professional. Those things I don't do because I don't have the tools or the desire to learn are ac stuff and complicated electronics in a gas furnace.

The problem for most people is, if you don't have the sense to know something, how do you tell that you don't have it? :-)

My previous house had an old (like, 40 years) Williams 5-in-one furnace. Me being too cheap to actually replace the unit, I chose to fix things as they broke. After removing the non-functioning electronic aircleaner, replacing the already removed by the previous owner humidifier, replacing the thermostat, blower motor and gas valve (which failed open one night!), the electronics failed. So, unable to find replacement parts that I was willing to pay for, I replaced the electronics with some generic off-the-shelf components. I also learned a lot about how HVAC systems work :-) After a day or two of fiddling with adjustments, it worked fine for for several years, and was still there when I sold the house. The new owner will probably replace the whole system... he seems like that kind of guy .

Humm...no....since a WHEEL, unless its a true directional, in the sense of pattern, not function, could care less. A blower wheel, however, DOES care what direction it is turning in.

[George E. Cawthon]

Yeah, I know that was lame, and yes I know that put the wheel on backwards won't change the direction it turns and the car won't spin. Hey, it was like all analogies... imperfect.

[CBHvac]

Good deal.

Like I think we all said..:)

Not from the two HVAC guys you heard from..or was it 3? No matter... A little advice for you, file it back...

The guys behind the counter, they dont work in the field. Most could not install a motor...thats MOST..not all, if you stood over them and told them what to do. A 3 speed units fine, but as I think I said before, it MIGHT NOT be what you need, particularly if the speed that you need is missing. This is why a real tech, will replace the unit, with that is supposed to be there. It might be possible to replace it with a 2 speed, but unless you know what the TD and TR will be after you do this, you can create issues you didnt have before. I say real tech...sheesh..who am I kidding? We all know that if you take

2000 so called real techs, you got about 100 in the bunch..

Not being an ass, but that you know of. A three speed GE 1/3 HP motor for

60? Good...hope they gave you that cap... Glad to hear its right, but at some point, you might really want to have a tech (when he services the unit for winter) run a TR check on it..thats temp rise btw....nothing fancy...but it can keep you from cracking your heat exchanger.

[George E. Cawthon]

Didn't mean to imply you were either, just a generalization to identify someone who shouldn't be allowed near a kitchen knife. But I disagree with you analysis of success. If you are either stupid or incompetent, it is unlikely you will succeed. If you are really stupid, you won't take advice, you can't learn, think you already know it, and you will fail. If you are incompetent you just plain can't use the knowledge you already supposedly have and won't get it right (at least most of the time it won't be right). Don't equate stupid with uneducated. The person that doesn't know much and is willing to learn, particularly if they have a gift for problem solving and an intuitive understanding will likely succeed.

Hi D, hope you are having a nice day

The questions you are asking are very basic and that is why we are trying to get you to understand that it isn't quite as easy as you are thinking it is. it is very easy to burn a relay or even easier to burn up that circuit board that most of the new ones have nowadays. all it takes is one wire in the wrong place and you have a nicely toasted mess.
