Central air cond air handler doesn't come on but compressor does.
If I don't turn the central air on in the morning, when the attic is cooler, the air handler won't come on but the compressor outside fires up. At night when the attic cools down, the air handler will work. I have replaced the T-Stat but that didn't help. Today, I put the fan on first, and it came on. I then hit the cool button and the compressor outside came on and all is fine. Previously, with the fan on auto, I hit the cool button and the compressor outside came on but no blower in the attic. Is there something in the air handler that senses heat?
