The E3 error code your Furrion Chill FACC10SA-BL is referring to a loss of communication between the control box and the thermostat.

What you're going to need to do is check your wiring and ensure that no wires have been damaged or pinched and are making a full connection in the thermostat as well as the unit itself.

You're going to need to also verify that the A and B wires are going to their respective slots. It's not entirely uncommon to hear about these connections being flipped in production by mistake.

If you're still having trouble after checking this out, feel free to come back and we'd be happy to take care of you.
