Question:
I have a 1988 National Dolphin class a model 3400 that I just bought. The Kwikee step was stuck in the open position. I removed the clevis pin and lubed the movable areas and was able to push the step back in. I removed the motor and hooked up a 12 volt battery to it and it makes a clicking noise but does not turn. I reversed the polarity and still just clicks. Can you tell me what the part number is for the replacement motor and the gear box also. Not sure yet if I need the gear box or a new control module.

Expert Reply:
The issue you are having with your Kwikee 28 Series Step is a bad motor. I do have an option for you but the cutoff date for replacement parts on Kwikee Steps is 1999. Therefore, they do not make a replacement motor that will work with your Kwikee Step due to its age. The only option you have is a full replacement, the Kwikee 28 Series Electric Step part # LC3747451.
If you want to switch to a more cost effective manual pull-out step you can use the Lippert Manual Pull-Out Step part # LC432678 instead which fits a 25-3/4" wide mounting bracket.

I have a 2006 Winnebago Outlook Class C with the kwikee 28 series step. It is currently having problems. The step extends normally but when the step is fully retracted the motor continues to run with a chattering sound for exactly 5 seconds and then stops. Also, the step will not retract when the motorhome is started with the step extended. Lastly, my understanding is that there is a safety feature that the step will stop extending if it encounters an obstacle. This feature is also not working. Do you have an idea if a bad control unit would be causing these symptoms? Would the Lippert LC432678 manual step be a direct replacement for the series 28 with the same bolt hole pattern. Thanks for your advice. Peter Anderson
