I'm not sure of the model, I do know that it is pretty old. We just had the outside unit replaced and it worked fine for about 6 months, but now the AC won't turn on, but when we try the heat it comes on fine. Any suggestions?

Is it just the outside unit that's not coming on or both the outside unit and inside blower both don't come on when calling for cooling? Please let me know and we can try a few simple test to narrow down the problem. Lee.
