We had a storm and lost power for about 6 hours, when power was restored my digital thermostat got hot and turned black in the readout window, so I replaced it, now my outside unit runs and you can hear the freon in the air handler A coil in side but the fan does not run no air at all. My air handler is a Trane XB80 and my outside unit is Trane XL1200.
Thank you for your time and assistance.

Bob.

Does your new stat have a fan switch marked ON/AUTO? If so move to ON and tell us what if anything changes.
