Well,
As I figured the what the end result would be, I too did the "Spray it with Silicone" thing and, it didn't effect the shut down ONE BIT. I tried other sprays, lubes, teflon spray and more, NO DIFFERENCE, it still shuts down if it encounters too much resistance in the locked elbows of the awning. As stated, if I let it sit after one of its shut down fits, and manually kink both spring loaded elbows, many times it will then come in. The joints, and possible binding because of lack of lube or accumulated dirt/debris etc., are not the problem in my case.
But, as I stated earlier, there is some form of thermal reset in the circuit board or relay that runs that little awning. Below is a video of my awning when bench testing it. I supplied 12VDC from a motorcycle battery I have around just for these type of things. As you can see in the video, when direct 12V is applied to that little motor, there is no hesitation for opening or closing, no matter how many times I test ran/extended/retracted it, even when the elbows lock in the open position, that little awing just kept on working.
But, when it's on the coach, it will throw it's "I'm not going back in, you can't make me" fit. But, if and when it shuts down, and I break out the ladder and an alternate source of 12V, and tie it directly to the leads on that motor, that thing ZINGS right back in, no matter if the elbows are in the locked-open position or not. There is a small black control box, just inside our first compartment that says Dometic Weather Pro and, it houses tiny relays that click when opening and closing that door awning. I have tried numerous times to figure out how to find which circuit or relay shuts down for a time-out, when it won't come back in but, no luck yet. I'm not smart enough to know how to trouble shoot that kind of system. Just click on the picture to watch the video.
