I had a similar problem. Never knew if the steps would come out when I opened the door. Sometimes I'd be outside nearby and suddenly they came out on their own without even opening the door. One time they went in while I was on them!!
The problem was solved when an RV tech changed the door magnet and connecting wires.
Same here. This is easy to test to see if that's the issue though. Just get a magnet and place it on the sensor. If the steps extend and retract when the magnet is moved towards and away from the sensor, then there's either too much of a gap between the magnet in the door and the sensor in the door frame when the door is closed and/or the magnet has gotten weak.
My simple fix was to install a shim under the magnet in the door frame. I found a garden hose rubber washer made a perfect shim.
