Kwikee Stairs failure rate

Doubt whether it is a step issue. More apt to be installation.
Find n indipendant repair man. It is likely something to do with the wiring between the step and devices, such as magnetic switch, ground connection or power supply.
It is hard to find intermittant problems. Just takes some patience and time. Many dealers lack both.

Mine went 15 years before they failed and that was due to my own stupidity.

Std problems with older units are low battery and corroded ground ... but your rig seems to new for those to be the issue ... but they are easy to check and you should do so anyway. You have had more issues with your steps than 20 RV's combined - I would call the mfg and see what they have to say.

Our Kwikee steps are original to the 15 yr old motorhome.
Only problems we had were lubing the parts at the motor and step joints with a grease. It gathered a lot of dirt and froze things up. Since then nothing but silicone spry. They still get stuck from road dirt when it rains hard sometimes. I think there is a shield missing to keep road spray from hitting as you go down the road. I had to squirt the step swing points or joints the other day with silicone. We have kept them extended and it rained and snowed.
On the way out here at a RV park in Ark I opened the door to exit and get us in close and putting jacks dwwn position for utilities and the step hit a railroad tie around their plantings and broke the pot metal arm that operates the steps from the motor.
RV Park Mgr came to the rescue with a part.
There is another manufacture that produces a set of steps that look almost just, like the Kwikee but has sealed bearings and joints I don't remember the brand but it is something like Seakins.
Then there are the new extend only type steps, which are a step up in design, that are made t fit the same openings but about1400.00 but can be had for much less.
If you can mange to get under the step area, use some diaelectric compound on the plug or electrical splices.The plastic like kind is much better than the older petroleum based diaeltric grease.
One electric is secure wash the steps off with lots of water pressure before lubing with silicone. Heat shrinks on wire joints if need be should keep all moisture out. Wires to the switches may need looking at. And...did someone turn off the step in the closed position by accident. Our control panel is right in the entry way.You can turn them off with steps extended and that is okay as the safety interlock when you put in in gear will retract the steps but better still have the switch in the on position.

As mentioned a couple of common installation/maintenance problems can cause this. When the steps don't work, have you looked under the the RV to see if the light was on? When it doesn't extend, do you hear any quick movement coming from the motor/gears?

Note* while trying t find the other brrand of step similar to kwikee for my own information I saw on the Stromberg Carlson site that Lippert no longer makes the RV step but Stomberg Carlson makes or has the parts.

Any capable 19th Century engineer could've built a simple and dead reliable set of manually operated steps. But you'd have to pull a handle or something, God forbid.

Anyone who has had an RV for any length of time eventually has issues with their Kwikee electric stairs. At the age of your RV, you do seem to be unlucky. I try to minimize the number or times the stairs extend/retract, when possible. Hitting a fixed object with the stairs extended WILL easily bend/jamb them which leads to early failures of the drive mechanism. The stairs live in a hostile wet and dirty place and regularly get sprayed with road debris so keeping them clean and lubed is always a plus. If you can shield the electrical components/connectors from moisture, that can only help. Hopefully your luck is about to change.

I am just throwing this out there, always wait till the steps are fully extended before stepping on them otherwise you are putting strain on the motor, gears and arm when you add body weight to it. That won’t cause the failure of a control board, but could be the reason for the motor and gear failure.

My guess on your intermittent issue is a sensor, wire issue. Corroded (Broken) wire to the door sensor, or as was mentioned bad ground.

There is two grounds for the steps. one is for control and one for the motor circuit.
