Welcome Back Light has stopped coming on when door is opened. Aisle switch is properly in off position. No fuses or circuits tripped or blown. This is a 2012 Bighorn 3070RL. I understand that Heartland changed this light operation after model year 2011, so I need help with the post-2011 operation and repair. I do notice what i think is a magnet attached to exterior door, under and parallel to the threshold and near the hinge side of door. Antone have similar problem and how was it solved?
