slide intermittently won't retract

I have a 2020 E-pro E20BHS. I've had a problem with the slide for quite some time. The slide has never failed to extend, but intermittently, the slide won't retract. When I push the retract button, the interior lights will all flash (assuming they are turned on) and the slide does nothing.

If I connect the extend wire to the retract terminal on the slide controller and then press the "extend" switch, the slide will retract every time.

To make things more confusing, the E20BHS has the Lippert Once connect box that connects to my phone. (I don't have the fancy version with the "tablet"). It just has standard switches, or use the phone.

The issue is the same whether I use the switch or my phone.

So the question is, is there a trouble-shooting guide for the one-connect? What is the expected "output" from the one connect?

Any wiring diagrams for the slide controller? What does the controller expect on the retract and extend terminals?

thanks

I think I would check the wire connection it may be that the wire that causes the slide to move in the retract direction may have a bad connection somewhere or is shorting against something. JMHO

^^^^X 2^^^^

The fact that it retracts smoothly when you switch the wires makes me suspect the same thing.

I'm taking it to a dealer to have it fixed under warranty. I would probably not do that, except there is also an issue with a chafed wire on the motor, so I'm hoping I get a new motor under warranty as well. (this is a totally separate problem).

Assuming I would replace the wire, any hints on running new wires in an RV? I'm a first time time RV owner, so this is a bit intimidating.

I don't think so.
I'm wondering if it's the switch.

It's definitely not the switch. I swapped the slide to the awning switch and it behaved the same way.

I would really like to figure out what the signal looks like out of the one connect. I'm pretty sure it's the wire, but would like to verify the signal. I don't think it's a constant 12V.

Those old analog multimeters were good for this, but you can still use your digital one. On the 20V DC scale, watch and see if the meter jumps around. On the lowest AC scale, you can see the amplitude of the voltage swing.

So the signal to the slide controller is pulsing, I did notice that using a test light. So the signal pulses the whole time that you are holding the button?

Ok, thanks. This will be great for future reference.

I guess this also means I can't just bypass the "once connect" and wire the switch up to the slide controller and send it a constant 12v to tell it to extend or retract?

Ok, I just answered my own question. I just found the installation manual and I can just send 12 volts to the controller to whichever terminal I need to operate and it will extend/retract.

figured it out...

It turns out that the wires for the slide and a few other things were run between the floor and frame so they were chafing bad, so. The wires were re-run under warranty and it seems to be working fine now.

thanks for keeping us informed.
