Help TRANE XE-80 furnace
 
I have a TRANE XE-80 furnace.

During general maintenance I accidentally broke the reverse flow switch on my blower assembly. I've ordered and received a replacement switch. For reference, the switch is TRANE part #SWT1696. This switch attaches to the blower assembly which is TRANE part #BLW00551.

The description of this switch is "Switch; Reverse Flow, Open at 140F, Close at 125, 1/2 In"

The part that I have to replace is #11 on this diagram.

There are 2 yellow wires that come out of the motor assembly and there are 2 places on the reverse flow switch to connect these wires.

My question is, does it matter what yellow wire goes where on this switch ?

No, it does not matter at all. It's just making and breaking. There is no "line" and "load" per se.

Are you sure ? It looks like the wiring diagram shows that there is a difference between the two terminals.

I've scanned the wiring diagram below. Look at the bottom to see the reverse flow switch. You can clearly see that it is marked 3 and 5 and each goes to a different place. Also the switch it self looks like it has some sort of polarity.

Again, my switch only has a 1 and a 3 on it, there is no marking of a 5.

What a slap in the face...

Do you know how much money I charge to repair furnaces? I told you your answer for free. Jeeze...

That is an ordinary break on temperature rise thermostatic switch. It has no polarity of any sort.

How many volts are going to the switch and how many volts are coming out of the switch after it is open?

squeed 10-08-2006 10:35 AM

mdshunk, No slap intended. I just wanted to make sure, it took 3 weeks to get this switch and I don't want to blow it out, especially since it is getting cold and I need to install it to use the heat.

Regarding redline's question. On the package it says this.

"Switch; Reverse Flow, Open 140F, Close 130F, 3/4 In., 120/240V"

So I think the answer is 120 in 240 out ?

Guys, I belong to a lot of forums and you never know who knows what they are talking about and who is just blowing hot air. As you can see from the number of my posts here, I'm new to this forum.

I didn't know that there were professionals who frequent this board to give advice. For a layman who doesn't know anything about HVAC, looking at a bunch of wires hooked into something that makes fire in your house is concerning. So I don't think that you can blame a guy for just wanting to be sure.

im new here too and also on other forums, you're right, cant tell a pro from a hole in the wall on these boards. Get as many opinions as possible, just remember, opinions are like a$$h***s, everyone has one. That guy should ask himself, yeah, why bother? and just go back to cleaning toliets at the rest stop on the highway.
Keep at it.

Hey, a guy signs up to type that especially for me as his first post. Both a profane comment and a disparaging remark all within a couple of sentences. I feel honored in some strange way. The fact remains that the man has his answer. (How'd you know that I clean toilets at highway rest stops?)
