The steps have 2 modes - (1) auto open and close whenever the screen door opens and closes; and (2) stay open ignoring the door opening or closing. But when in this mode, starting the engine causes the steps to retract. At least they USED TO work that way.
Starting the engine no longer causes them to retract when in mode 2. So mode 1 works as it always has, but mode 2 only partially works. The steps stay open no matter what.
I've had the rig 6 years, and this is the first time I've seen this behavior. I'm pretty sure they worked properly when I dropped the RV off at the shop (2 months ago!), I almost always have the steps set to mode 2, and I think I remember the steps sliding out when I arrived at the shop to drop it off. But to be honest I can't swear to that.
When I picked it up, the door was closed and the steps were out, so it was definitely in mode 2. They just didn't close when I started the engine and drove away.
Anyone ever see this type of behavior, or can hazard a guess as to what might be causing this problem?
Thanks!

Hello, on my 2016 class A the steps ignition override quit working recently after multiple interference hitting my leg still loading for a trip while the engine was running. Found # 23 fuse burnt by the brake pedal. It said "Cluster/run accessory" in the book. I didn't notice anything else not working but didn't look either, so with the key on and screen door closed replacing the fuse engaged the steps and fixed it.

I figured the most logical thing would be an upstream fuse/breaker, even though it seemed kind of silly to have 2 breaks on one line.
Started looking at the fuses under the hood, but they were all heavy duty. I figured the fuse I was looking for would likely be 5 or 10 amps, not the 30+ amp fuses/breakers I saw under the hood.
Then I remembered that there is a fuse panel in the coach - in a VERY inconvenient location - at the floor, to the left of the steering wheel! I had to lie down on my side, chest facing the brake pedal, butt up on the transmission hump between the driver and passenger seats - oh my back!
There are 27 mini fuses on that panel. And Doug, you're totally right - I looked up the fuse panel layout in the Ford F53 chassis owners manual, hoping I could determine which fuse to check. But the figure in the manual didn't look ANYTHING like the panel in the vehicle! I checked them all - the bad one was the 26th that I checked, of course - 10 amp.
Anyway, I replaced that fuse and all is well.
Thanks to all for the help and advice - it's very much appreciated.

I don't see how to make the IMG tag work ... so here's a link instead:

I've never this type of breaker trip, but I assume that when one trips, the white plastic piece pops out.
Well, tracing the cable did not work out well. The loom for the cable leading to the vehicle side of the 4-wire connector leads right away into a larger loom containing many other wires. I followed that larger loom; it snaked under the floor to the opposite (drivers) side of the RV. It then lead into one of the basement compartments. Unfortunately, that area of the basement is boxed out with metal. So, looking at it from the inside of that compartment, the loom is behind a metal plate.
This is directly under the galley area, so I'm going to dig around behind panels in the galley lower cabinets. Maybe I can find that loom and continue my search for the source of this mysteriously missing 12 volts.
But now it's time to cook a Memorial Day steak! Enjoy the rest of the Holiday!
Thanks again all.

But the vehicle side has 3 yellow wires and one white! So if I follow the loom and find the source of the bundle, it'll be a bit harder to determine which of the 3 yellow wires connects to the yellow ignition override wire on the control module. I'll have to use a continuity tester ... likely with a very long lead! :B

Ground the clip and touch the tip to both windows.
For this test the ignition will need to be in the ON position (Engine need not be running but ignition in ON)
Bright Bright - Fuse good
Dark Dark - No test (With the ignition ON this should not happen)
Bright/Dark or Dark/Bright Fuse blown.
if you do not have an Intelletec Battery Control Center check every fuse block/box/holder you got.

I checked all the fuses and breakers I could find, but all were intact.
Not sure where to go from here. I figured once I get daylight back tomorrow (Sunday), I'll crawl under the rig, and follow the split loom cover for that cable back to its source. Maybe there's a bad connection somewhere, or perhaps an inline fuse blown - ok, an inline fuse is not likely ... I'm just grasping at straws 🙂
Hmm, I wonder if the service guys did something to cause this - maybe they disconnected something and forgot to reconnect it? I'm pretty sure this problem was not present when I dropped the rig off. Well, following the wire might have me discover that, if that's what happened.
Thanks for all the suggestions and help!
