I have 7 - 1 1/2 x 3/16 coil pins left over from a MH I sold several years ago. PM your mailing address and I'll send them to you. You can buy me a beer if we ever meet up in our travels !

Thanks Joe, that would be great. I have sent you a PM with my address.

I dropped it at the post office about 10:00 am ET Friday---- I saw one post that it takes 8 -14 calendar days-- since I'm about as far as you can get from BC, I'd guess it will be on the upper end of that range.

Diplomat_St_Poodles,

Sorry it took so long to respond. Between work and actually getting out to enjoy the RV the last couple of weekends, I haven't been on the forums much.

OK, so, I have the same slide out controller you do. I examined it physically and observed it's operation. It DOES NOT have a circuit built into it to cut power to the slide out motors when they reach the end of their travel. (There is a PIC chip (microprocessor) that's wearing a bogus part number so it can't be ID'd, but I really don't think that is working as a current limiter, just simple logic for the switches.) The relays on the board stay engaged until I release the IN/OUT button. That said, neither of my slides has ever broken a shear pin.

The slides will activate until the end of their travel, then slow down and ultimately stop. That's when I let go of the button. If I hold the button past that, the motor's apparently stall as I don't hear anything. When I release the IN/OUT button, I can hear the slide controller relays click to disconnect the power.

I did see in a pdf document I have on GBM slide operation where they specifically state to release the IN/OUT button once the slide reaches the end of it's travel to prevent damage to the wood molding. If you want me to send you the pdf, PM me with a real email address and I'll be happy to send it to you.

I'm guessing & hoping that installing the proper shear pins on your slide out should solve the problem.

If you continue to have this problem and everything appears to be in proper alignment, the only other thing I can think of is that the motor was changed for one with more torque than the original. The motor has a gear box built into it, and perhaps someone changed out an original one for one with a different gear ratio. When I bought my replacement motor, I believe I saw different gear ratios available.

My main front slideout and rear (queen bed) slideout use the same motor and my rear slide goes out noticeably quicker than my front slide due to the lighter weight. If you don't notice that difference in speed, perhaps that motor has a lower gear ratio and therefore is applying more torque once it reaches the end of the travel.

That's just a wild guess. I'm hoping for your sake it's just the shear pins.

Good Luck,

~Rick

I'm not an electrician so I don't know the part names, but odds are you have a bad electronic part that stops the slides. (maybe somebody knows the name) The part acts as a limiting switch, but it isn't a limiting switch. Is a self contained piece that senses a power surge when the slide is fully open or fully closed. Basically when the motor starts to draw more power when the slide hits the stops the device senses that power draw and cuts off the power stopping the slide. Your power steps have the same device that stops the steps when they are fully up or fully out. This device would also stop the slide if you opened the slide into a tree or wall.

Thanks for all the information. I will PM you my email addresse for the PDF.

The motor on all three slides are the same. I have owned the MH since basically new so they should be the original ones.

Hopefully the shear pins are the issue and the ones Joe is sending from Florida will solve the problem.

I would have thought there was a limit switch of some sort but it would appear that there isn’t one. We thought the controller would sense a higher power draw and stop the slide. According to the builder of the controller it does not do this.
