The heat or the blower runs?

JoshDta

When I disconect all the wires and turn on the furnes on the on/off switch it still turns on and runns

The blowe runns right now, I don't feel any heat

Still runns no heat yet

Go down look in the bottom door and see if your unit is flashing a fault code. There should be a sight glass

I don't see a glass door everything is metal and it's enclosed, the only door I can open is where you can light up the gass

Well the control board shold be in the lower door with the blower inless you have a down flow furnace. Then the blower will be on top.

Well I am in a condo so I have a small room, the furness is on the bottom and the blower is on the bottom too, I know that because I took the filter off and I can see the blower.

OK no control board there?

How does a control board look like ? I see the blower through the filter opening on the wall.

No id don't see anything, the blower is exposed nothing around it has some wires connected to it that is all.

Mounted to the front of the blower.

Turn off furnace.
Take all wires off the stat.
Tape the blue wire.

Connect two wires at a time.

Connect yel to red; Turn on furnace. What happens; turn off furnace

Connect yel to white; what happens; turn off furnace

Connect yellow to Green; what happens; turn off furnace.

Keep filling out the table with the number corresponding to what happens.

I don't see that in the fron of the blower

Here is what I see

What's the "jump rope" for?

Are you referring to the white bcable that hangs? That is my cable for TV TV cable

I connected Yel to Red- turned the furness on - Furnes turned on - I turned the furnes off.

The same sequance happened whan I connected yell to Green, Yellow to White

It doesn't matter if I have anything connected if I turn the furness on it turnes on and blows.

I was.

I think the rest of the guys are trying to see where the tstat wires connect to. If you go that route, you have to follow the wires.

If your confident that blue wasn't used, then filling out the table will work.

There may be up to a 5 minute delay on the AC unit, but I doubt it.

When I took the old tstat off the blue ire was taped with electric tape. Im not sure if the furness should turn on when all the wires are disconectted?
