Heat and ac troubleshooting?
I am trying to install a new thermostate. I have a Red wire a Blue a Yellow a Green and a White. I have hooked the red into the heat power and blue to the ac power and the green in the green for fan and the white to white for the stage 1 heat. Nothing works. Please help. When I decided to replace mine it was only working for the ac unless you switched the red and blue wire then the heat would work but it wouldn't kick on and off. So I thought it was the thermostate.
