Expert Reply:
E3 is a communication error code between the unit and the thermostat. Check to make sure your wires have no kinks or damage and are making a full connection in the thermostat and in the ac unit.
You'll also need to make sure the "A" and "B" wires that make the connection are in the correct ports. Some times in production the "A" and "B" wires can get flipped, or in your case you may have accidentally flipped them during your swap out to the Replacement Premium Wall Thermostat for Furrion Chill RV Air Conditioner - Single Zone # FACW12PA-BL
