WARNING: Be careful where you place your hands and arms when reconnecting plugs on the step. The step motor is likely bad and needs to be replaced. If a positive or negative voltage is present when the door switch is activated, then the step motor is getting power, but not working. The motor rotates in the reverse direction when the polarity is reversed (negative voltage). NOTE: It’s not important whether the voltage is positive or negative. Then use a multi-meter to check for a DC voltage reading of around 12 volts when the door switch is activated. Here’s a quick test for a bad motorĭisconnect the power cable from the motor. Then check if power is getting to the step motor. They should line up when the door is closed. If you don’t hear anything, determine if the step is getting powerįirst verify that the magnet in the door and door frame switch are aligned. The problem is likely the step motor, gear linkage or step frame getting stuck. The switches and cable connections are probably working. If you heard anything trying to move, you’ve got power to the step Start by listening for any noise when the door opens and closes. Symptom: Step does not move when triggered So continuing down that path, here is the approach I took to troubleshooting my step problems. In my experience the most common symptoms of a broken Kwikee step are either nothing happens when the door opens and closes, or the wrong thing happens (usually accompanied by an unwanted noise). It should take you the rest of the way towards diagnosing your step problem. I think you’ll find Lippert’s troubleshooting instructions to be pretty good. Then I’ll point you to a troubleshooting guide that Lippert published for the Kwikee RV Step. Let me start by sharing my approach to troubleshooting a step problem. The metal arm is connected to the metal bar with a pin and lock wire. It’s secured to the step frame with four nuts and lock washers. It’s just a gear, an arm and some grease. There is no power connected to the gear linkage. When the motor moves the gear, the gear moves the metal arm either in or out which, in turn, moves the step. The gear linkage has a metal arm that moves the step in and out. It will stop turning when it can’t move anymore (i.e. It drives the gear linkage in forward or reverse when activated by the controller. The motor is mounted on top of the gear linkage with three bolts. You can find the manual for your Kwikee step model here. Refer to the Lippert manuals for your specific Kwikee step model for the correct wiring. There should also be a power cable from the controller to the step motor. You’ll find several colored wires going into the controller. Step Controllerįollow the black wire bundle from the connector to the black box mounted to the step. The rest of the switching for the step occurs in the step controller board. NOTE: If you have Class A or Class C motorhome, the steps will typically retract when the engine is running (regardless of the override switch position). If the switch is on, the step should stay out. This toggle switch is typically located near the door and is used to keep the step extended when parked. If the magnet in the door is not perfectly aligned with the switch in the door frame when the door is closed the step won’t activate. The magnetic switch is located in the lower portion of the door frame and is triggered when a magnet in the door passes in front of it. It triggers the step to open when the door is opened and it closes the step when the door closes. There are two switches that control the expanding and retracting of the step. How does the automatic step work?Īutomatic steps are triggered by the opening and closing of your entry door (or screen door).
