AC OFF code keeps coming on. Is this the thermostat or a more expensive problem


If you are seeing this AC code on your thermostat screen that usually means that the thermostat is losing power. If a furnace is overheating the limit switch will shut the burner off cutting power to the thermostat. Check your air filter and make sure all your supply and return registers are open.;
