I have been troubleshooting my Flat Floor Electric Slideout (FFES) for some time. It "amps out" about 3 times from full extension during retraction. I have inspected for roller operation and ramp clearance, temp., bypassed wiring with 8ga power and ground, adjusted Intellitec control to max. Still no answers. I was looking at 007's wonderful sticky's about slide motor operation in 2018MADPOG.pdf. My slide's single motor K900 has a rubber boot on it. With +12 disconnected, I tried to turn the 5/8 reduction gear nut, but would not move.

So... could this be the action of the motor brake, does this motor even have one?

Would the brake still hold the motor even after the power is removed?
Could a partially releasing brake (if so equipped) cause the slide to amp-out?
Does anyone have a thorough explanation of how this brake works?

I have searched the sticky's on this but unable to locate answers so far. Thanks to all in the forum for the untiring support to their fellow RVers.

That looks just like my motor, and there is indeed an electric brake under the boot - screwed to the end of the motor. It is pretty simple to test, as the wires are "plugged in" and can be disconnected. You then just need 12 volts to them to test. Brake simply clicks and you can see the tabs engage. Hope this helps.

The brake needs to be electrified to release. it is possible that it could amp out if not releasing.

Incidentally, mine had a loose connection and was causing intermittent issues.

Searching the Klauber model number online it appears yours does not have a brake.
This is what one with a brake would look like, you could easily remove yer rubber boot to check. I have no idea why yours is 'amping out', either the motor or controller.

Thanks for the input, I guess I will have to remove the boot and see for myself. After thinking awhile, I assume the brake shoe is spring-loaded so when power is applied to the motor and brake, a solenoid energizes, lifting the the brake. This way you would have a brake-on motor, even without power. If the brake was dragging a little it would add to friction loss at the beginning of the retraction. After a little movement up the ramp, friction may reduce below the amp-out threshold allowing normal travel. If my motor has a brake, I will disconnect it and test retraction. If it goes up ok, that was it!

p.s. It is not the controller, since I have two alike and just swapped them with no change.

Do you have this manual?

Thanks, yes I have it along with others gathered from the sticky's. They have been very helpful.

Just got in from checking on motor. It does have a brake (see pix). To test theory, I removed brake from motor, tried slide and no change, so not the brake dragging. However, when I went to reassemble the brake, I noticed the brake wires had no marked polarity. wires from motor are red/black but brake wires are black/black. Tried it both ways and it did not seem to matter, but I sure don't want slide coming out when traveling. I tried to use the 5/8" gear motor nut to manually move the slide. With wrench cw, could not turn nut. With wrenching ccw nut unscrewed (not just turning, but coming out of housing). Any idea about that?? If I can't get any ideas, I will try to track down Klabuer.

I am at a loss... But if you were turning the nut while the brake was engaged (de-energized) I would expect it to hold.
From the manual, it sounds like the slide would move in/out easily, disengage the gearbox and see if it is binding, the manual does mention adjustments.

Good luck!

I talked to Jim in Klauber engineering today. He said brake wires have no polarity since it must work going out and coming in. Manual override nut unscrewing is not right. It is held on shaft by lock ring that is probably missing. Otherwise, no idea on slide issues. If I get time, I will try to use manual override to retract slide using a torque wrench to see how much the effort varies to raise it the first few inches.
