I am replacing mine with a hunter 44860 progammable thermostat. My wire colors are Yellow,Green,Red,White,Blue, and Pink(appears to be just a lighter shade of red?) Turned unit on but no power or fan. A little confused because of wire color.

if done according to rule of thumb, the green wire should go to g post on a good tstat, red to r,, white to w, yellow to y,, blue is normally taged to the c=common post,, but its really according to how its wire in the furnace

with a hunter tstat, you will be lucky to get it working
