Hi Alan, with your introduction post, you posted to your wall which goes unseen. To get some help, please copy your message and go to the Home page of the forum. Open "New Discussion" and begin a new thread.
In the meantime, please give us some more detail. Are you at a full hook up site? Were you heating the cabin or just hot water or both? Can you check the outlet that the Alde plugs into for current? Is the Alde display visible? Besides the 2 fuses on the top of the Alde, did you check the 12v fuse in the breaker/fuse box? Is there anything else that is not working - fan, lights, A/C?
