Magnetic Door Switch Works Opposite Of What It Is Supposed To

Question

Question:

I have a 2011 Newmar Bay Star RV with electric steps. The label on the step frame says Coach Step DBL-STANDARD and LCI Model # 171317. The control module is LCI-164889 and motor LCI-163669 was replaced with 300-1406. I have found conflicting info on how the magnetic door switch operates. Door open = switch closed and door open = switch closed. According to Newmar, the magnetic door switch replacement is #72851, or vendor part #165041. I just replaced the control module and motor, and steps are still not working. I ordered switch #369299, but it works opposite of my current switch. I have tested all wiring, and this is my last item. Can you tell me which one I need, 369299 or 301694? Thank you

If you ordered and tested the Replacement Magnetic Door Sensor for Kwikee Electric RV Steps # LC369299 and they work backwards, then you need the Replacement Door Switch for Lippert for Lippert Electric Coach Step # LC301694.

Lippert makes two switches that work opposite of each other, one completes the circuit when they are connected, and the other opens when they are connected.

For some reason Lippert uses two different magnet setups for their steps and the only difference is that they operate in reverse of each other. So in your situation the solution is to go with the opposite magnet switch so that it operates properly.…

Answer 6

The Lippert Components Kwikee Step Switch Magnet #LC369299 is a normally open circuit setup that completes the circuit when the door magnet is closed. Because of that there isn't a positive or negative designation that you need to worry about.

I spoke to my contact at Lippert about the issue you are having with your steps. The first thing they told me to have you check is that your screen door is secure because if there was too much movement on the screen door, that could then cause the…

Answer 10

The difference between the color sensors does matter. You have to match the colors you have now otherwise the steps will operate backwards. Since you have the black ones you'd want the part #LC369299 that you referenced.

Answer 12

It sounds like you switched the two wires when reinstalling the motor. I contacted Kwikee and there are only two reasons they would work in reverse, the switch is wrong or the wires were switched. If you recently upgraded the motor in your Kwikee…
