Red face Door step help

Any one know if there is a fuse that runs the door step motor?
If so, where it could be located?

Leaving for a trip in the morning and while loading the MH,
opened the door and as the step was coming out, it stopped half way.
Light still works as it should with the door switch so I am guessing
that's not the issue.
I can however see a small wire hanging with what looks like a round
glass fuse but it holds no fuse that I can tell.
One end is open and it looks like a small pin just inside.
I can not find a location that it would plug into.

The step has dropped down as it does about an inch and started
out about 1/2 way.

Guess I can travel with it like it is but I don't have the road clearance
I would like. The step now will work in and out about 1 inch by hand.

Any assistance is appreciated.
Thanks.

We have a Hurricane 29M which protects the steps with a buss fuse located inside the coach on the firewall left of the brake pedal. If you have steps made by Kwikee you can go on line to download the product service training manual which includes the wiring schematics.

If your step is made by Kwikee try this website

This manual has trouble shooting sections.

Mine stopped working once and I just unplugged the wires going to the motor for a few seconds and plugged it back up and it worked again? Donít know if this will work but worth a try.

Know that our motorhome may not operate with the steps not securely locked in the closed position.

Update:
I had to disconnect the motor link to the step and wire it in
the up position to make this trip.
After reading the reply post here I took a look under the dash.
Did locate a fuse box with 3 or 4 fuses labeled for the step.
All fuses in this box are good. So, I am guessing the issue
is not as simple as a fuse unless there are others elsewhere.
So, once I get home I will need to turn this over to the shop
for eval and estimate.
If there is more info out there I should check please continue to
let me know.
Thanks again.

You might be able to disconnect the activator arm from the step and then push your steps in. You could then try to extent and retract the steps by hand. That could tell you that the problem is lack of lubrication, a broken weld, or broken shaft, rivet, or bolt.

Looks like you have a 2018 ACE and I don't think they use the older BCC (Battery Control Cabinet) from RV Custom Products. The BCC box was mounted in the engine bay in front on Driver's side and it did have a 25 amp fuse inside for the step motor (fed off chassis battery). I am not sure what the new ACE's use for latching and battery interconnect relays now though. If you still have one in your ACE I can provide more details.

UPDATE:
I did check all fuses I could locate under the dash and found them
to all be good. Note: There is one or 2 located in the same fuse box
identified for the door step that are not available from any parts store
or from the Ford dealership. I ran all over looking for this fuse and
was told it is a THOR fuse box (and it is) and fuse added by THOR and
I would have to contact
them with my MH ID information to have one shipped out.

The door step motor died.
Replaced it and all is working again.


Thanks again to everyone for your input.

Glad to hear you got it working. Im still working on mine. LCI is sending me another motor Hope it works.

The wire you saw hanging down that wasnt connected to anything. Was it purple?? If it was its an extra wire to attach a second light You can leave it or cut it off. GOt this info from LCI

The knowledge here is priceless! It's like walking in a nursing home and asking all the sweet little old ladies working on their puzzles..."anybody here got a good recipe for mac-n-cheese?"

Step finally working. I checked the gear box and found two broken teeth at the end of the gear. Replaced the gear box and all is good now

I think we all should buy a Prevost, towing a DRV and hit the road as mobile mechanics. People would cheerfully wait for us with open arms.

Gritz, that's high dollar with all the same issues. LOL
But your correct, people would love to see the help wagon pull up and would pay to play.

Good. I replaced mine. New motor. Hope it last longer that 1 year.
If not, I hope I can get a big discount on them at an even dozen.

Did you get the rec for the mac-N-cheese?

I was in my buddies new ram truck last week with an automatic step bar that was so smooth solid and quiet compared to these poorly designed stairs on class a rigs. How much is the difference in price for this?
