    Why does my Carrier Network Hardware have a heating/cooling mode conflict?
    • E
      Elizabeth WashingtonAug 26, 2025
      If your Carrier Network Hardware system is experiencing a heating/cooling mode conflict, it means there's a disagreement in the operation modes of the units. This can happen if the system is set to cooling or fan mode, but a unit is sending a heating signal, or vice versa. To resolve this, ensure all units are set to the same mode. Specifically, all units should be in cooling mode for the system to stay in cooling mode, or all units should be in heating mode.
