Getting ready to go on a trip. I wash the RV roof with a brush and then rinse the sides to get soap, dirt etc off the RV. I noticed that there was something cycling within the furnace box. I cut the power, batter, etc to stop the cycling. Waited a couple of hours, turned the power on, still doing it. This winter, the furnace would not ignite after a rain storm. Apparently, something is going on with water affecting the furnace. It did the same thing this summer when I wash and waxed the RV. Pop the outside furnace cover, did not see any water? I'll post a couple of short videos and you can hear the cycling. Also, I can't find the breaker for the furnace. Only seen AC circuits? I guess I'll have to wait another day for it too stop.
Here is dropbox link to video, having trouble attaching to forum:
