An E3 code on a Furrion Chill Replacement RV Air Conditioner for Dometic Brisk Setup - 15,000 Btu # FR42PV means a loss of communication between the thermostat and control box. 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.
