Kwikee Step magnetic switch and magnet

Sorry I am late in getting back to what I found. My coach doesn't have any magnetic switches of magnets. On the door frame hinge side there are four 3/16" domed brass pins that have a slight spring load and have a 1/16" travel.. On the door there are a matching set of spring loaded domed brass pins that have about 1/4 inch travel. Doug pretty much nailed it in an earlier post. The top two pins are for the auto door lock and the bottom two are for the step. I downloaded a Kwikee manual and followed the troubleshooting steps. By unplugging the 4-way connector I was able to diagnose the problem. After 14 years of service the step controller died. I Googled every number I could find and didn't have any positive results. I called Kwikee now Lippert and spoke to a very knowledgeable woman. She researched to see if there was a replacement for the controller. After about five minutes of cross referencing she gave me a part number 379606 which was the replacement for the old controller. I was able to purchase it for $155.65 with Amazon Prime. The controller came with new wiring and two types of magnetic door switches that I didn't plan to use. I removed the old controller and installed the new one. Plugged in the cables and it worked like a charm. As an FYI my step model is 903809000. Thanks again for your input.
