What do furnaces use anyways? 15amp 20?
12 gauge wire or 14?

Thanks

There is no such thing as a voltage leak. They were giving you a line because they don't know what they are doing.
Did you try to jump the R to W? You can remove the T-stat and do it there if you feel more comfortable. We need to start with the basics before we go any deeper.

Hey ya John
I agree with ya on that.

I will jump the wires tonight,see if i can get a spark or click or anything atleast.

I will update later tomorrow

Thanks again for your help.

There is a phenomena called voltage leakage. And in a overtly technical examination of the furnace fault, it could be used to describe the furnace fault.

However it does go above and beyond the normal tech jargon one would use when explaining a furnace problem to a HO.

I guess the repair guys could have been electronics experts.

But since they walked away with a basicly Uhh I duno I dout they were. Now I myself couldent walk away. I have to figure it out or it will keep me awake at night. It would make me nuts not to figure something out! I guess that why some of us find our way to thes sites. We just have to keep thinking and figuring things out. It feels good to solve problems.

you should only as a test. 15 amp 14ga is fine

Not to rule out the "Leak" but if you dropped neutral or reversed polarity

OKay

Here is what i had done.
I ran a direct line from the circuit box to the furnace wire.

I had jumped the thermostat Red and white wire.

After powering the unit back on and having the t-stat set to auto.
Nothing happened.
The only thing i had seen,which i dont know if it has shown up before, on the t-stat. When i switch to auto" error" comes up.
But when i set the furnace to the " on" position, it blows out cold air and no error comes up.

I had even reset the t-stat and when i set it from off to auto, it took a few seconds then error came back up.
Just says " error "

I did not see or hear anything come on or light , not even a click, which i thought normally would happen.

Anyone know what the next step would be to try?

Thanks

Let me know what you think i can do next Guys.
Its cold out here in the North east.

=)

I would take the thermostat out of the equation. Disconect it compleatly from the furnace and jump only the r & w at the furnace. Also make sure you have hot and ground correct if they are reversed it may not operate.

adman77 · 01-30-2009, 07:12 PM

HI
Okay, i had disconnected all thermostat wires from the furnaces circuit board.
A red,white and green wire.

Am i jumping the red and white thermostat wires itself?
If so, that is what i had done before.

If you are refering to another red and white wire somewhere on the furnace, i may need some more help on choosing which ones.

Thanks

JohnH1 · 01-30-2009, 07:20 PM

The r and w termemols on the furnace itself were the thermostat connects to the furnace

adman77 · 01-30-2009, 07:47 PM

OKay,this is what i tried.

I had jumped the t-stat wires on the circuit board.
The furnace blower came on for about 2 seconds then stopped and that was that.i could not get it to repeat that again.even unplugged power and all that.

hvaclover · 01-30-2009, 07:52 PM

If you didn't disconnect the white and red wire at the board you blew the stat.

adman77 · 01-30-2009, 08:10 PM

Yikes.I blew my stat?
I just checked it, it has a little fuse in it,looks okay.
I have one of those electronic t-stats

I had put the cover back on and reconnected the red and white wires back to the circuit board.

What can i do next?

hvaclover · 01-30-2009, 08:21 PM

Be the first stat I ever saw with a fuse.

What kind do you have?

adman77 · 01-30-2009, 08:25 PM

its a robertshaw 9600 digital tstat
