2016 R-179 Slide Totally Dead

First, thanks Stephen H. for your great visuals of the controller box & always trusty tech help. We had our slider go out 18 months ago, and I’ll tell you our experience: first thing I did is use my smartphone to video the specific error blink-pattern that the controller flashed upon the failure of our slider to push out. I also set the phone on slo-mo to record the pattern that way since the error blink pattern flashes such a quick pattern. That info went to our trusted RV repair shop. The result was that one of the little upper (horizontally-mounted) slider motors had corroded with moisture over time - it was basically barely turning the gear in the L worm track. The other side motor was just about worn out and weak but not corroded. The dealer ordered them in and did the somewhat labor-intensive job of replacing both of the quite-buried drive motors. Unfortunately it was close to $1k for the whole operation but comforting we can go on a long trek with virtually new slider drive motors. Since we live in Western NC mountains there are heavy rain downpour days during a storage summer, and we think eventually moisture intrusion and rust got in behind the rubber gasket and deteriorated the cylindrical slider drive motors. To protect our investment we upgraded our off-season Rpod storage to a slot with an aluminum roofed shelter. We can now skip “stressing out” for a long time about any slider functional issues on a long camping excursion. And, should we ever decide to sell & upgrade, (no current plans) the documentation of new slider drive motors would be a big plus in selling the unit. (‘17 Hood River 179). Hope this helps & sorry about facing this “possibly” 1k maintenance repair. Hope your actual repair is far less!

I have a 2019 179 and the slide controller is mounted under the fridge behind a wooden sight screen held in place by 3 screws.  Meaning that the controller is accessible whether the slide is extended or retracted. Hope this helps    

Update:   I finished making harnesses going to the two motors and put the slide out and got to the storage in the ottoman.  The power wire going to the controller had broken off and I have a feeling it might have zapped the controller by touching the negative.  I moved the controller to the wall under the refrigerator and connected everything and slide only tries to move in one direction and code is motor 1 (one blink) and Power drop out (2 blinks).  I believe my motors are good since they are working when I go to them directly, reversed the motor 1 and 2 wires to the controller and the controller keeps saying motor one power drop out, if there was wiring problem I would have expected the problem to move to motor 2 but the code does not change.  Right now suspecting the controller which I know do not go bad that often but again if connector which broke and was hot touched the ground on the controller then I can see a zapping issue.  Will do some more testing.  Tempted to tap into the original motor wires and connect some wires to them so I can manually put the slide in and out bypassing the system but using original wires.  It is easily doable.  Putting the controller in manual mode does not let me move the slide.
