New Nest Install..AC works...Heat does not

[Scedarst]

New install and AC works great..when heat is turned on..the fan blows but does not light the gas.  I have a American Standard Gas Pack.   Here is a pic of the wires when attached to old thermostat

Did you wire it something like this?

Red - R to R

White - W1 to W (jumper toW2/X2 not needed)

Yellow Y to Y

Green - G to G

Brown - B to C

[Scedarst]

I did the following

Red - R

White - W

Yellow - y

Green  -G  (says it does not see connected on reset/resetup)

Brown - B not to C

Should Brown go to C and not B?

[Patrick_Caezza]

Yes, move the brown wire to the C terminal.

If you are still not sure, you can look at the terminal block on the control board in the furnace/air handler and see where the brown wire connects

Didnt work with my dual fuel/all in one gas pack...connected to my heat pump only upstairs unit and it works great

Hey there, 

Thanks for the update. I am glad to hear that it works now on your heat pump system. As for your dual fuel one, you will need to have a trained professional set it up. It’s important for a professional to assess the requirements for your specific dual fuel configuration since choosing incorrect options for a dual fuel system can result in damage to your system. We recommend to contact a local pro.

Best, 

Melba
