Unhappy Steps quit

I have a 2004 DSDP model 3810 and the steps have suddenly quit. Is there a fuse I could check or what do you'all suggest. With all that wisdom out there I could certainly use some direction. Thanks Don

I was just reading about an RVer in Florida with the same problem on another forum. Someone suggested cleaning then using a good spray lubricant, lub all of the pivot points. It worked. Yours might be more but try this first.

Are you able to check for 12 volts at the step motor?

Hi s.j.sharks,

The power steps are considered part of the automotive 12 VDC. They are powered by the chassis battery(s). My coach is diesel powered. The automotive fuses are located in the most front basement compartment on the driver's side of the coach. The power step fuse is fuse #7. It is a 5 amp fuse. You may need a flash light and magnifying glass to read the fuse locater sheet inside the compartment.

I do not know if your coach is gas or diesel powered. Gas powered coaches have the automotive fuses located in a different location than diesel powered coaches.

If the fuse checks out good, the rest of the diagnostics will be on your back under the coach. Be careful when under the steps. If they activate, you can get hurt. Check the plug that connects the motor wires to the power source. Check for 12 VDC when opening the coach entry door. If there is 12 VDC, check for a good ground connection from the motor to chassis ground.If you have a good ground remove the gear that connects the motor to the steps. When the door is opened and closed, the motor should run. If it does not, a new motor is needed. If the motor runs, there may be a bind in the steps. With the gear removed operate the steps manually. Lube all gears and pivot points.

Some steps have two fuses, one for the switch and one for the motor. They will be in the dc distribution box or on some coaches, under the hood in a fuse compartment...

In addition to the step fuse in the front compartment on the drivers side, there is a fuse in the electric compartment. That is where the electric cord is and under a cover. The fuse is on a pigtail hanging down. One fuse supplies 12 volts to the steps when the engine in running and the other fuse supplies voltage when the engine is off.

I had step problems and it took me forever to find the second fuse.

..........Don, before you get too involved, lay on the ground away from the step movement and find the ground wire connection. Remove the bolt attaching it to the frame and clean really good with a wire brush ( I bought a wire brush to put in my cordless drill ) which does a great job, WALA, no more problems, JMHO, good luck and travel safe.

One quick check, best performed AFTER DARK

When you open the door, does the step light come on? IF yes fuses, door switch and 12 volt are all good to the controller.

If NO. Well it might be a burned out bulb.

My steps have a 20 AMP fuse that is inside a big black box in the inverter/charger compartment.
