I had my Keystone electronic board fail on me twice.
Once on delivery and a second time at the start of our second season camping. Both times the boards were changed with no cost to myself. (I have a great dealer who fights for his customers.)
The second & final failed board was replaced with a toggle switch model vs. the touch screen system that came with the 2014 trailer.
It works great, however one draw back is that the remote no longer operates the landing gear which for me had been a real plus when hooking up.
NOTE:
Some have discussed changing the board themselves. You should know that it is not only the board that needs changing but also the remote control electronic panel which is situated inside the front storage compartment and mounted on the wall just above the battery. The dealer brought in an electronic technician who managed the switch over. It was about a 3 hour job.
