The level up controller on our 2014 38RSB3 wont turn on. There is plenty of 12V power to the rest of the trailer but nothing happens when I press the on button on the controller., Unit has been in storage for 10Moi. But hooked to 30Amp power and new batteries about 2 moths ago that have been on a maintenance charge since installation. The battery disconnect switch has been engaged to disconnect the batteries. Any suggestions on what might be causing the controller to be inoperative?
