Thanks JBarca and enblethen for your thoughts. JBarca, I didn't make a typo, but I wasn't very clear. Yes, no matter if the coach interior lights are on or not, the fault codes are the same. But only when I turn the dome light on does the clicking go away. So I like your idea that maybe the dome light drawing some power means that the 12V system isn't quite right..a short or something. But it does seem odd to me that when the sink light is drawing power is when the fridge stops it' cycling. And yes, you understood correctly that the interior fridge light blinks off with each clicking of the fridge. I'm not sure if I can post videos to this forum, but I'll try. Okay, this is going to make me sound like I've got no business trying to self-diagnose this, but I'm not 100% clear where to put the leads on my multi-meter to test the voltage coming into the refrigerator terminal block, but I'm going to do some googling and see if I can figure it out. (I did check the 5amp fuse for the reefer in the main fuse box.) I believe that where I need to test is outside the coach in the reefer panel where the power comes into the control board. And to your point that the clicking might in fact be the gas igniter, I am just not clear what that sounds like. The gas has been filled and the lines have been bled, (including running the gas stove-top for a few minutes.) The clicking definitely is still happening when in Gas Mode also, but again, it seems electrical in nature, because the interior reefer light is also going on and off with each click.) Thanks again for all of your help everyone, I'm still investigating!
