Need help diagnosing power step malfunction
When my power step extends or retracts the motor continues to run.
This is intermittent and, so far, I can get it to stop by causing it to partially extend and retract a couple of times. Is there a sensor that needs replacing, perhaps a connection that needs cleaning, or do I need to replace the motor?

If your steps are ; Kwikee ; brand, the end of cycle is a function of the control module . The module monitors the amp draw of the motor and when the mechanism gets to the end of travel the amps spike and the module cuts power .
However if there is any grinding when the steps come to the end of travel , then you probably have a broken tooth somewhere in the gear reduction mechanism that will require removal and dis-assembly to locate the broken part.

I had a similar issue with my steps. In my case the gear mechanism was loose at the motor so the steps never got pushed out far enough to hit the limit switch. Bolting it all back together fixed the issue.
One thing I've learned about my older coach (98'). When something stops working, take a breath, step back and look at the issue. I've been able to fix every single issue myself. Good luck with your issue.

Replace the motor assembly
We just had the same issue. Ended up replacing the whole motor assembly. Bought the replacement on Amazon for $70.00. three bolts and a pain of a wiring connection to get off and it is fixed.
Here's the link for Amazon https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Well, our Kwikee steps just started doing the same thing today.
I placed an order with Amazon for the motor assembly and it should arrive in a couple of days, but what about the Gear Linkage assembly from Amazon. Do I need it too?

There is plastic worm drive between the motor and gear set that can strip. There are also metal gears inside the gear case that can lose a tooth.

You'll need to open the gearboxes up to determine which is the problem. Most of the time if the steps are having problems at the end of the travel the final drive has damaged teeth. If the problem is between the two end points the motor drive is the most likely suspect.
Just had to replace the motor drive on my steps and here is what the damaged drive gear looked like -

My linkage seemed to be fine, just the Motor assembly was all that I needed. There is one plastic gear in that assembly that strips all the time apparently.
When you lower the Motor assembly you will find two washers, a metal gear and a short metal shaft. Those few items may stick up inside do to grease, so watch for them.

Just a note: important to NOT stand on steps until they are fully extended, this can harm the plastic gear.

I change the motor assembly on our stairs like I change the oil. I'm up to 5 replacements so far.
At least twice a year, we travel with friends/family and someone steps on the stairs while they are moving...the gear is gone in a nano-second.
Getting really good at swapping the motors...and I always have a spare with me.
Did anyone ever find a source for the gear alone, it would easy enough to replace if I could find it.

I called the motor manufacturer the last time the steps went out. They do not sell parts individually, and the gear is not available anywhere (made in China). Unfortunately you have to buy the entire motor assembly.

There is no "customer service" at Kwikee. My steps on a 2016 Bounder failed with 15,000 miles on the rig. E-mailed Kwikee asking why so soon...they never replied.
I don't deal with companies that treat customers like that...
