“I received it. I had another service co out here this morning and somehow the system is working ok now. They initially diagnosed the board in the air handler as needing replacement because the thermostat was not communicating with the the board while they spoke with Trane and then the system started to work. Two different evaluations with yours needing replacement of the thermostat and their replacement of the board on the air handler. At this time instead of replacing either one or both I will wait until it breaks again and then most probably replace both items. Because the system is working ok now I don't know what else to do other then wait till it breaks again. Do you have any other suggestions ?”
