RV owner stymied by stuck-out step

Dear Chris,
I have a 2011 Newmar Gas Class A. The steps automatically retract when the engine is started. They didn’t retract yesterday. The only thing that happened prior to this is the engine battery went dead and I started it from the house batteries. Any suggestions, since I can’t drive it with the steps open? —MaryAnn

Dear MaryAnn,
The step controller has several inputs: the ignition, the magnetic or mechanical switch, and the power switch on the wall by the door. When the ignition is turned on, the default is that it is supposed to retract the steps. With it not doing that, I am concerned that there is either a connection problem, a blown fuse or a controller issue.

Try using the power switch by the door. Cycle it to ON and open and close the door. When the door is closed the step should retract. If it doesn’t, that’s two inputs that aren’t working, so I would then try testing the incoming power to the step using a test light or multimeter.

The owner’s manual for the step should be in the owner’s packet in the coach, which will show which wires to test. If not, the manual may be available online at the manufacturer’s website. If there is no power to the step, then testing the circuit back is the next thing, starting with the fuse or circuit breaker for the step.

If there is power to the step, then it is possible that the controller or motor has failed and must be tested. The only way to get rolling with the step retracted is to go underneath and jump the motor to 12 VDC and try to move it, or disconnect the mechanism so the step can be manually retracted and tied up until permanent repairs can be made.

Hope this helps!

    A freind’s motor home had a similar problem and he found loose connections to be the problem. One was so loose he was able to turn the nut several revolutions before it became finger tight.

    You did not mention checking the ground wires. There are two ground wires if either fail to ground to the frame the steps will not work. It is one of the first things I check after experiencing the steps not going out on my rig.

    Be certain that you be extremely careful if you’re under the coach working on your steps. If they suddenly move you could lose body parts becaus they aren’t going to stop when they get to you.

    On the step issue, I have twice had the magnetic switch to come loose, after the second time I siliconed around it, step has not given me another problem in the three years since.

      Same iIssue happened in our 1 year old Mercedes chassis Class C. Stair extended but wouldn’t retract. On the door frame, I found a small magnet had come loose. There was also a small square of double faced tape with nothing attached as well. Putting 2 and 2 together, I reatached the magnet and presto, problem solved. At home, I replaced the factory tape with a much stronger 3M product. If this happens to you, be careful to replace the sensor in exactly the right position. I suspect the folks who assembled my RV didn’t position the sensor correctly and had to move it which likely ruined the tapes holding power.

        MaryAnn, I’m not sure about your coach but my Entegra had three fuses for the steps. There were two in the outside bay under the drivers seat and one inside with the house fuses.
