This thread is getting looong and many views off things that can go worng when under stress.
Most of these links I have been supplying are in the QT's links and some of them are old but most coach's will have the 12v motor driven slide.
Newmar does make changes with good old design's but find out things were just fine with the old design.
This thread is in
QT's # 3 in PROBLEM SOLVERS now and you will find it in the
Newmar irv2 search engine.
Sorry I have come up with another
old thread that has a living room stop rod broken weld on the extended slide.
I have read the whole thread and have added the many problems I have seen since being here if I find or remember any others they will be here.
Its hard to come up as to why these brakes occur, if the rods adjusting stop nuts are not placed correctly, they used the wrong nut not locking nut, brackets not mounted correctly or wrong size for operation but with the operation of slides the problem will eventually arrive.
A broken stop rod does not mean your slide may have a problem extending or retracting the slide control will sense the rise in voltage current when slide hits the fixed wall of coach.
Why broken brackets, gear housings, after rewriting the slide thread information, one thing I have notice the pots on controls older ones,
people have found turned up to high and high torque motors just keep operating and causing damage, the control senses the raise in current in a normal operating motor and will shut down motor, the
pot set to high only defeats the control shutting off motor.
I would check the settings of your pots on controls to only operate the motors with only what is needed for smooth operation of your slides.
The pots will not increase the speed of slides Newmar slides operate slowly as they are intended to.
Older coach LR Slides may need increase of pot to get the slide up its ramp.,
Members now reading, have a pretty good view with pictures, that you can check area's under slides when your under them to see something that may turn out to be a problem.
