If you have Kwikee steps, the following is normal;
Normal operation is ignition off, step switch off, when you open the door after turning off the ignition the last out feature causes the steps to extend and they are suppose to stay out. Open and close the door as often as you like they should stay out.
Turn on the step switch and the steps will actuate with opening and closing the door.
If you are sitting still and the ignition is off and the doors are closed and the step switch is off, turning on the ignition will cause the steps to retract.
To exit your rig and have the steps close after shutting the door, you must have the switch on.
At that point there is a small current draw that will eventually drain your batteries.
If your steps are not operating in this manner, something is wrong. The tech may have screwed up and messed with stuff. If your steps are Kwikee, there is one on/off switch, one ignition sensor in the control module and a magnetic switch on the door. I believe if your rig is like mine you'll find the magnetic switch magnet on the screendoor frame.
There are three fuses in the circuit if it is installed properly.
Look in your manual or Google, #888 Manual. There you'll find everything you need to know about your steps. Do not expect any help from Lippert. If you need parts, Google the part you need and buy from the cheapest source available.
They are very easy to trouble shoot and repair and there are hundreds of threads about all of this but the manual is the best source of how the steps should be installed and tested.
If you need to leave the steps extended to exit before storage, I have the step switch on shut the screen door and then reach through the hand hole and turn off the switch and activate the battery disconnect. At that time "ALL" power to the system is disconnected.
