The thermostat would come on (no batteries needed) but the compressor wouldn't kick on. When it did after waiting for about 20 minutes the air was warm. It was switched out for the original with wiring as in photo above and the compressor and cool air came out within 10 minutes. I'm not sure but o think I miswired the new one just not sure how.

What I see in the picture is a jumper between y1 a/c and w1 heat. That is not good. remove the jumper and add the white to w1 the wire looks like it is hanging in space the picture.

That picture is the old picture (older thermostat) and the only way the ac works is in that picture. The new thermostat had no jumpers but wouldn't work.
Customer reply replied 11 months ago
the white one was in w2, the picture was taken after that was disconnected.
