You need to help us to help you.

What brand and model of thermostat was originally installed and what brand and model did you replace it with?

Do you have a heat pump or separate air conditioner and furnace? What are the brands and model numbers of each piece of equipment?

Did you turn off the circuit breakers for the air conditioning AND furnace BEFORE changing the thermostat?

Several pictures of the air conditioning unit (outside) and the furnace may help to identify the problems. Pictures of the two thermostats also please.

Pictures need to be uploaded to a photo hosting site (www.villagephotos.com is one that I use) and then the public URLs for the pictures posted here.

i know what ur going tơo say blank blank blank blank ;-p

This is how it should be.

R = 24 volts ac
Y = Cooling
W = Heating
G = Indoor blower

It looks as if you have R, Y, B, and G colored wires. You may have to go to the airhandler and confirm where each wire lands there. Have you jumpered out R+G to confirm you have 24 volts ? The indoor blower should come on when you do this.

all i have too do it
R is the red wire
Y is the yellow wire
W is the white wire
G is the blue wire

or

R is the red wire
Y is the blue wire
W is the black wire
G is the yellow wire

i think it 24v
when i test it it give me 26v
when i hook it all on then test it some wire drop down too 12v

and 1 time i got it all 26v i think but i don't know which is the cooling and which is the heating now u just give me the heating wire and cooling wire i should got it

thank alot they keeping on yelling at me about the heating n a/c none stop it working fine y don't u just leave it alone gotta fix stuff then broke it hahahah thank again

The reason I wrote R=24volts etc... is that somewhere along the line someone may have chnged things and since you don't recall where they were hooked up on the original stat then you should go to the airhandler and see where they land in there.

i try jump from r to g like u say the blower come on but it like is short somewhere only goes on half way does blow air in too the vent when i turn thr thermo on off the power on the therm telling the temp but when i turn it too ac or heating the themo temp when off like no power but when i turn it off again it went back on

r=red
g=yellow
y=green in my case it blue
w=black

currenly like that only goes on half way

damn i hate that damn pplace
