I have a 2021 2800BH. We just purchased this so it is one year old and we are the second owners.
The the furrion thermostats, main cabin and bedroom, back light does not come on. I viewed many videos of its operation and they always light up as soon as a button is pressed.
I have had this to a Grand Design dealer twice and they just keep ordering new thermostats to install with no luck at all. I think the problem is in the wiring somewhere. The wire harness in the wall has 6 lines, only four are used on the back of the thermostat.
It operates, I can see the temp and menu but there is no back light so without getting my face right in front of it or shine a flashlight on it it is difficult to see.
Has anyone had this problem? What did you do to fix it?
Thanks
