Earlier I had no blower on my York split system, you all advised I change t'stat. I installed new t'stat and blower came on as advertised. But now it doesn't get cold. Outside fan is running. I had to put sides back on unit as it got to raining so I couldn't tell if compressor is coming on. But unit got cold yesterday before t'stat went down. I did a recheck to make sure all the wires on new t'stat were in the right place. What I'd like to know is what things I should check for come daylight. I figure I'm overlooking something connected to changing out the thermostat that is preventing it from cooling. Thanks for your help yesterday. Ed
