Kwikee Steps acting in reverse

I have a 1999 Winnebago Grand Tour and the Kwickee steps broke a short time ago. I needed to replace the whole motor, controller, and gear assembly for moving the stairs. When I got all done the steps work in reverse. When the door is closed the stairs open. When the door opens the stairs close. What could be causing this and how do I fix it?

Hi and welcome to the forum.

Hopefully one of our experts will be along soon to help out but I'd bet it's something simple like having the 12v polarity reversed?

Best of luck.

Rick

Switch the two wires to the motor. My daughter did the same thing on a electric window. We switched the wires and everything was as it should be.

The older units work on different contact switches they are backwards from the new control units. One works on open contact and the other works off closed contacts.

It doesn't sound like an issue between different switching or control units, it still sounds like reversed polarity. As long as the motor doesn't use ground for one side of the circuit, switching the two wires to motor should make it operate properly.

Someone wrote on another forum to swap the wires to the magnetic switch on the door. Never had to try it, but it sounds easy to try it.

That does nothing... It will not change anything A switch just connects the two wires together.

Agreed. Switch connects 2 wires, but then what? Does it open or close at that point?

Reversing the polarity might work? Dunno. Never tried it that way.

Polarity to the motor is wrong, has to be. Reversing wires to the mag switch wont do anything at all.

The new unit would have come with a new door contact switch. Your old door contact switch MUST be installed. As mentioned above the differences being the switch either being normally open or normally closed. DO NOT REVERSE THE WIRES TO THE MOTOR to solve your problem otherwise the logic of automatically closing the step when the ignition is started is reversed.

A switch does not have polarity It is like touching two wires together! One side of the switch is ground, the other side of the switch goes to the controller unit brown wire. Reversing the wires does nothing!!! It still is grounding out the other wire

Yes, there are NO (Normally Open) and NC (Normally Closed) switches. The Kwikee controller uses a Normally Closed switch.

I disagree with your statement!!!

The door contact switch ONLY needs to be replaced if it is bad. I am 99.9% sure that ALL motorhomes that use the Kwikee steps come with the same switch which is a Normally Closed switch. One side of the switch is ground, the other side of the switch goes to the controller unit brown wire.

Reversing the wires to the motor will most likely solve the problem and if it does then the ignition wire will control the motor properly!

For anyone that needs the Kwikee manual... http://support.powergearus.com/techdocs/875.pdf
