Electric Slides Motor

If the slides are power gear there are several interlocks and other things that can stop them.. NOTE not all interlocks are present on all systems and then there is the controller....

Ignition interlock, Some want it on. some off
Parking break interlock Some insist on parking brake set
Transmission interlock, only in park
Turn key interlock (mine failed, it's a basic switch)

These can become... iffy

Next is the switch.. Sometimes switches get dirty and won't switch and/or have to be presseed "Just so"

Now the controller
Power gear controllers sense current. If anything causes the current to climb above the set point they shut down.

LOW BATTERY VOLTAGE on a motor causes higher current.
Binding, some obstruction. Higher current.

End of travel.. Well that's a given stalling the motor = Higher current.

I know one would think that as voltage goes down so would current but Motors are variable inductors (Inductance varies with speed) and because of this the slower they go (lower voltage) the higher the current.

The 120V breakers had nothing to do with it. You have a 12V auto-resetting breaker that is tripping for what ever reason and your problem is going to return.
I would find the 12V breaker and replace it (they're cheap). Otherwise you are going to get stuck someplace with the slide out.

The part will look something like these and you will need to get the amp rating off it: link

Good luck,

So i went back out there after letting it sit for several hours. Switched off all the breakers and back on and now all seems well. Not sure what happened there but oh well.

My slides have a thermal cutout that will stop everything if they overheat. They're in the basement. I just wait a sec and then things work again.

Breakers are for 120v, not 12.

Often the slides (and awning?) are powered directly from the battery, not from the DC fuse panel. Might be two positive red wires on the battery, one for the DC fuse panel (and converter) and the other for that.

The positive wire for the slides should have a fuse on it near the battery or maybe a DC circuit breaker that can be reset.
