Hello, my name is XXXXX XXXXX I will assist you today
Most times the color code is correct, but sometimes people just don't go by it.
The terminald are almost always the same though
The C stands for "common", this is the neutral from the transformer. It may or may not be needed at the thermostat and also goes to the outdoor a/c unit.
The Y terminal is for the air conditioning. You would have a wire coming back from the thermostat and could also have a wire going to the a/c unit attached.
Your a/c unit probably has a white from the C terminal and a red from the Y terminal going to it.
The R terminal is the 24 volt hot wire to the thermostat
The G terminal is the wire for the blower, usually a green wire
The W terminal is from the thermostat and is for heat
I am replacing the circuit board currently installed. A friend of mine diagnosed a bad circuit board and I ordered a replacement. I have the replacement and it doesn't look difficult to replace but I think he might have moved some wires around during his diagnosis.
He had jumped the R and W together.
You would need to check whaat wire color is going to each terminal. such as Red to R and so forth.
Then do the same at the thermostat.
R and W should not be jumpered
There is a red wire attached to the Y terminal.
Please give me all the wire colors and the terminal they go to
Just a moment...be right back.
C-white coming from a R+W combo...R-Red...W-White...G-Green...Y-Yellow and a Red wire from the same R+W combo attached to C.
The R+W combo had a brown wrap on it.
I am not sure what you mean by combo, is that a short jumper wire from one terminal to the other?
No...it's a brown wire with a red and white wire inside. It leaves the furnace and appears to be headed toward my a/c unit just outside.
I will list how it should be connected. You will not need any jumper wires
Red to the R
White to the W
Green to the G
Yellow to the Y
Then the Red and white wire in the brown jacket
The R goes to the Y and the white goes to the C
Got it...thank you. I will give it a go. I suppose the only way to tell if I did it properly is to start the furnace. I don't have testers.
any other words of wisdom for me?
You may want to check the thermostat end of this, color code should match
If the thermostat has a R terminal, you are good to go
ok...just pop the cover off, right? I have a digital thermostat.
If it has a Rc and a Rh terminal, you will see a jumper from the Rc to the Rh
Yes, the front should just pop off
Please let me know if you have any problem
I installed it a few years ago and have no problems with it.
I will be in and out this morning
Thank you...it shouldn't take me too long. I have everything ready.
Thermostat does have a Rc and a Rh and they are jumpered.
I am still here
