By limit mechanism, are you refering to the circuit within the motor assembly?

Roll shades up and Velcro straps work good. We have had 4 rolled up at one time for extended periods

I can see where that would be a problem now. Some have only had a few motors go out (me) others, numerous motors. I talked to a 2013 Cornerstone owner while in ID. He originally had the green motors, with several failures. All were replaced with yellow motors and not a problem in over 2 years. I can see Entegra's reasoning, where do you draw the line? If I had numerous motor failures and the Red motors turn out to be problem free, then yes I would want all of mine replaced. If I continue to only have a few go out, I am happy with replacement motors and a couple of spares to carry. Traveling with clipped up shades is not cool for a $300,000 plus MH.

Besides, you can clip them up if they won't go up but if they won't go down you can't do that, you are stuck without any shade at all.

That's going to look cool....hanging my Batman towel in the windshield of a $300,000+ MH for everyone in the RV Park to see.

Noel said they can be unwound against the motor, hard but it can be done. I hope I don't have to try.

It is difficult for me to see these comments from Entegra about limiting response to shade outages with replacements, given what has be stated by Tadd Jenkins. My sense is they are starting to change their tune (not a surprise); with the switch to MCDs, makes me wonder how much of this is United Shade pushing back, as they just lost their biggest customer, with no hope of getting them back. I think that leaves United with Thor as their only user.

Not true. If one shade goes out the ones down stream on the same circuit are not affected.

FYI, Lost toll window night shade followed closely by front passenger night shade. Hope to get them both replaced in Bend at Beaver coach on Oct 29th. I took ownership July 20,2015.

That is correct. Each shade has its unique channel on a multiplex shade controller. If multiple shades are programmed to a common button they are still on their own unique channel and do not share any common wiring, except for the power source that supplies the 16 channel shade controller.

The programmable limit mechanism is built into each shade motor on a circuit board and is part of the motor assembly. The motor may be fine but if the PCB is bad it will not operate.

Thanks for that clarification. That was my conclusion after disassembling the one motor. Any idea what is zapping the PCB?

Voltage fluctuations, static electricity, heat, even interference from fluorescent or LED lighting can mess with some electronics.

I'm hoping a system sensitive to EMI/RFI/ESI is not the case. This stuff was solved in the 80s.
It must be something simpler.
Best wishes!

Cruzer · 10-07-2015, 06:16 AM

It depends on how "price sensitive" the motors were designed. Maybe the technology in China hasn't caught up yet.

It may have been solved/understood in the 80's, but it doesn't mean that everyone implements these solutions. It always comes down to cost when implementing a new design. The only thing downstream from a design is manufacturing and some/most engineers could give a rats a$$ about this.

When looking at putting something to market, EMI considerations do come into play, but it all depends on where the product will be used. New products, the FCC regulates Class A and Class B emissions. This is for home and commercial use. Going into a motorhome, well it MAY not require any of this testing.....Just a guess on my part....
