AC reverts to heat pump (follow up)
My Dometic Penquin 13500 AC, 2006, would cool for 2 minutes and then revert to heat pump. Several suggested the reversing solenoid (coil). No other ideas so I cut off the coil from the front unit, installed it, and it solved the problem. Now trying to find one. It fits over a post and has to be exactly right. It is 120 Volt although a 24v might work with a transformer.
