Well you don't give us a lot of information to troubleshoot with but here's a couple of ideas. remove the inside air intake covers and find the wire that looks like a phone line connection, remove and plug back in firmly. The #2 daisy chains from #1 Do this for both airs and also at the thermostat. If this does not work you can do a reset on the thermostat. Just a thought but may work for you.
