I've had this RV since new. Yesterday, I was putting it away after a trip and as is my standard practice, I removed all power from the rig via a knife switch. I then noticed a chipping sound. Further investigation revealed the chipping is coming from somewhere in the ceiling near the fan over the island. But here is the weird part: both Dometic thermostats are illuminated. At 10 second intervals, both thermostats blank and I hear the chirp. Keep in mind ALL power is removed from the rig. Where are the thermostats getting its power? Ghosts?
