I have a 2005 GB cruise air with 3 slides. Livingroom, kitchen and bedroom.

When bringing in the slides I hold down two switches. When the slide is completely in or out it stops automatically and I let go of the switches. All three slides operate in this manner.

Awhile ago I brought in the bedroom slide and when it reached its limit instead of stopping it sheared the pin. First time in 10 years. Thinking it was an obstruction I had it checked, all good. Replaced the pin (not an easy task as it’s behind the motor). This worked for approx 10 in and outs and once again I sheared the pin. My dad watch the motor that drives the rod and gears as it came in and when it gets to the full out or in position he could actually see it torque.

If I carefully bring in the slid and stop it just prior to it reaching its limit I save the shear pin. But if I don’t stop it quickly enough I break the pin.

This is a picture of the slide out controller. There are two. I’m assuming 1 operates 2 slides the other 1 slide. (There was a 4 slide option on this MH)

I contacted the company who makes this part and they say it does not control the stopping of the slide. That the motor does using a thermal break.

Now I’m really confused because my RV person said this module controls the stopping using current.

Any ideas?
Doug Rainer?

Some of the wires looked to have been over heated or are they just discolored.

My system has a torque adjustment also. I do not have your system. Sorry I was no help. Doug might jump in later.

This is a picture of the 2nd control module. It appeared to run two of the slides. The other 1 just the single slide.

[image]

It has wires in R1R, R1E, AND R2E. in the signal spot. On the wiring diagram these go to the wall switches.
The wires labeled SWITCH go to the ignition lockout. Keeping you from moving the slides out while the MH is running.

A bit more info from America Technology. This is their reply to my inquiry.

Hi
I spoke with the engineer who designed this (AT-RLM-024). He assures me that it is not a current sensing module. It has been replaced with the AT-RLM-044, but it is not a current sensing unit either. If your tech would like to call and speak with one of our techs, he is more than welcome to. He can call 800-238-2687 and just ask for tech services. Please let me know if you have any other questions. Thank you and have a good day!

Thank you,

I would look to see if the slide(s) are not adjusted correctly. When they get nearly closed the systems jambs up and breaks the shear pins.
You need to locate the make and model of the slide mechanism.

Might look for a limit switch

I have done emergency repairs on a couple of these in campgrounds over the years. In all three cases someone had used garden variety screws as replacement shear pins. Not saying that is your problem but ensuring you have a shear pin with adequate metallurgy might something to look at

Thanks for the response. I’m assuming they are the correct hardness of shear pins. My local RV repair shop sold them to me.

We have looked everywhere for one. There is nothing in the area of the motors or the controllers. My documentation seems pretty good and they show nothing on the schematics in my manual.
