  If your Carrier Air Conditioner is acting erratically, unpredictably, or not responding, it might be due to interference from cell phone towers or remote boosters. Try disconnecting the power and then reconnecting it. You can also try pressing the ON/OFF button on the remote controller to restart operation.
