2016 Thor Miramar 34.1 - Furnace Ignite Cycle after rinsing RV Sides

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:

Use a hair drier on the circuit board to dry it. Don't melt it, just medium warm and keep it moving. Later seal the trim where it meets the body. That is typically where water will accumulate and drip inside.
