Question about Heating & Cooling
Sounds like you have a loose/broken 24volt wire. I would look at the wires comming off the transformer, the board, and the thermostat connections first.
Somewhere you are losing 24 volts. Obviosly the transformer is working, so you are just losing control voltage somewhere.
Check all connections at wirenuts, stackons, etc.
