Interior Stairway Cover

We have a 2002 Holiday Rambler Ambassador and the Stairway cover was working fine and seams to have a mind of it own

It is not retracting as it should, the switch on the dash does not light up as it should

Once the air is dumped you can push it in and it will stay in

Any thoughts?

Interior Stairway Cover

If itís air operated vs electric there should be a air solenoid, possibly on the firewall, that controls the extend/ retract operation. Ours failed and was acting erratic or not working at all. Make sure that you locate it before ordering so you get the correct one. Iím not familiar with the electrical units, so no help there.

You indicate it is powered by air pressure, mine is also. When it stopped working properly I finally discovered the cause was the air cylinder that moves the cover. The seals inside the cylinder were so dry they had trouble moving. I removed the air line to the cylinder and added several drops of special air tool oil, reattached the air line and began moving the cover in/out. After several moves it began moving with only air pressure.

Three years later it still works as designed.
FWIW, Winnebago told me the proper air pressure to my cover is 45 psi.; that's assuming your air pressure regulator for the step cover is working properly. I replaced my minature regulator with one off ebay, cost- less than $10; as recommended by Winnebago. It even came with a small pressure gauge to set my pressure accurately.
UPDATE: My double-acting air/electric(12V) solenoid was also sticky, a few drop of air tool oil solved that too. BTW, it is obsolete, so a replacement must be cross-referenced to a current one, if required.

Good morning Doug; On both my previous 2000 Windsor and my current 2001 Windsor I have had the same problems you have had. As Ray mentioned the seals in the air cylinder can get dry and if that is the case I would follow his advice. The problem I was having was dirt, crud or rust getting into the Mac valve the controls the air to the step cover. That, should be blue in color, valve is mounted to the firewall in the gen. compartment. I have written a procedure here before that works for me to get the, whatever, out of the Mac Valve. As for your switch not lighting a possibility that the light has burned out or you lost 12V power to the switch.
As to clearing the Mac Valve/solenoid. On the side of the valve are 2 small screws that control how much air goes through the valve to the air cylinder. Crud and etc. get stuck at those adjustment screws. To clear the valve make sure your step switch is in the retract position. With a very small screwdriver, I use a jewelers screwdriver, back those screws all the way out. There should be a stop on the screws so they do not come all the way out of the valve body.
Now have the coach up to full air pressure, tanks full. Have some at the step cover because when you select extend on the cover switch the step will rocket out at full speed and someone should be there to slow the step down before it hits the stops! Next hit retract. Do this a number of times and the crud should be out of the valve. Now run those 2 adjustment screws into the valve until they bottom out. Now back those screws 2 full turns out and see how the step cover works. You can adjust those screws in and out for how fast or slow you want the step cover to operate.
Sorry for the long post, but this has worked for me for years. Never have had to replace the Mac Valve/solenoid. Hope this works for you and good luck!

What poster above said , I had to disassemble mac valve give a coat of air tool oil to spool and some in both lines to cylinder, the threaded portion of cylinder is broke off as well. I plan to drill and tap if not too hardened. At least now it doesn't stay out and have to climb over it. You can bench test with 120 psi air and 12V source.
Some air tool or marvel mystery oil in inlet may get both the valve and cylinder working with removing anything but source air line. 1/4 a thimble full/ 1ml.
