I posted two questions a couple of days ago about our blower motor in the air handling unit being stuck on "on". This has been going on for quite a while. We have a Trane XL1200 Weathertron unit that is 17 years old. What is causing the blower to be stuck?
Second question. I salvaged what turned out to be an almost new squirrel cage blower and have turned it into an exhaust system for my shop. I am trying to learn a little about welding and my wife ruled this had to be installed. It is a GE 1/3HP 115V 5.80A CIS B INS-Cont air over. It should have 3 speeds but when I hook up the wires of each speed lead I get the same speed over all of them.
WHY?
Thanks...Bo Whalen

You'll find that a lot of questions that don't get answered on any HVAC site are because there aren't enough details to give an adequate answer, so we move on to one that can be addressed. I'd say your fan running continuous is probably a bad fan relay. As far as your do it to yourself exhaust fan, you need to partially block off one side of the opening to the blower to achieve proper amperage or you will burn the motor up and your wife will be even more upset with you.

First one. Yep, just about has to be a relay stuck somewhere. Maybe a bad thermostat.
Second one. I thought the consensus was that you burnt the motor. After review of the posts, I would tend to agree.

yeah, I looked back at previous post after I replied and I'd say he let the smoke out of it...that's why I call them " do it to your selfers", instead of "do it your selfers"

If you have so much experience then answer my question. I AM NOT trying to do HVAC repair. I figured the three speed wires were connected to a different winding on the motor and when one was energized it would run at that speed. Appears that is not the case. The first time I tried it it didn't work. Maybe the motor was already burnt up when I got it, I don't know. It's funny how ya'll get hopped up when someone appears to be trying to do something on their own. To me it looks like there are a lot of posts that come from individuals and they are answered. Just forget I asked

Motor still runs fine which I also said in an earlier post. Just can't get more than one speed out of it. If it were "burnt" up would it still run at all?
I've got two more motors to "burnt" up. I was just hoping for an answer to my question. Just assume the motor is fine. How do you get it to run at the 3 speeds, or at least the other 2 since IT IS RUNNING fine at one.?
That is all I want to know. Can someone help?

You get it to run at a different speed by hooking up a different speed wire to 120v hot. One speed at a time. If it's not getting the right input voltage, it won't matter what you do. If changing speeds doesn't change speeds and the correct voltage is being supplied, the motor and / or capacitor is shot. Lol, that's all there is to it. Yes occasionally you'll get one that still runs after letting the smoke out, if you didn't smoke it too bad.
