Step won’t shut till 10 minutes down the road

April 06, 2020, 08:41:00 pm

Need some suggestions.

-Step goes down a little slow but not bad
-Step will not close immediately, it usually takes between 10-20 minutes, sometimes longer, I've only seen it close with the engine running.
-applied magnet to door and solenoid is clicking each time I apply it with the key turned on but won't close
-not sure how to check 12v since power is screwed onto one end of valve and no way to get to the leads on the female end with the power (should I cut wires to check voltage?) see picture
-took apart norgren valve, cleaned and greased and reinstalled. Same issue

Don't know much about valves so specific suggestions with simple instructions would be much appreciated

Thanks for suggestions in advance

Thanks Barry and Cindy and Pamela & Mike for your prior posts

mine is set at 60 psi then you can fine tune it through the norgren exhaust.

check the regulator and make sure its getting pressure.. sounds like something is stuck until it bounces enough to pop it loose and do its thing

Valve is probably worn out if the cleaning and lube didnt help?

how was the inside?

Mine are both pegged at 60psi, step and step slide.

Wasn't dirty or anything, not sure what I should be looking for?

I tried rebuilding mine originally.. they were full of cocaine .. ok maybe not but it was white and taste funny..

Just bought new replacements and I havnt had to worry about it.. Id rather spend on new than rebuild most of the time.. .. Most.

Mine too, do you remember what replacement you used. Was there any modifications needed?

how much pressure is showing on the regulator?

If you have about 60 psi then turn the regulator down to "0" and remove the air lines from the valve to the cylinders, turn regulator back up to about 60 psi and you should have air escaping on the N.C. port. Try actuating the valve again with your door or magnet and see if the air switches from the N.C. port to the N.O. port. If not then the valve is stuck or has an obstruction. If it does and you have plenty of air flow on the N.O. port, try connecting just the N.O. port back up (this port should retract the step) and check for "blow by" through the cylinders.

Disclaimer........... I have a U280 GV and this worked on mine......... yours may be different.

Good Luck!

60 psi,
What do N.O. Port and N.C. port mean. Sorry haven't fooled with these before.

Normally open and normally closed.

Ill see if I can find the norgren as they changed since I ordered and only difference was the mounting.. Nothing a zip didnt fix

Step and step cover cylinders

I would replace both.. I ended up doing the other a year later and the part number was discontinued but this should give you a jump

Lol to much stuff going on at my house.. posted the wrong part.. or maybe I didnt.. time will tell. Check the throw and the overall measurements to what you have if you decide to replace the cylinders

Try this one

they are the same.. this is what I have in my notes

Don't know how. What do you suggest Chuck? One thing I have now is time. Honey do list is getting shorter.

Will do what Foretraveler suggested today.
Anything else I'm all ears.

The exhaust ports on the norgren.. they are the ones with the little filters on them.. IN and OUT .Back the nut off and take a flat head screw driver and move it in or out ... that will slow the air down from exiting or allow more so that the step is able to come up or down. Maybe the filter is clogged or the exhaust is needing of adjustment.

Foretravelers switched the lines between the valve and cylinder and the step closed fine.

So looks like the valve is stuck?? Air is only flowing out the bottom port. Nothing is flowing out the top port when I actuate the valve.

Removed the valve and will try to clean the exhaust ports and all fittings on the valve.

If all else fails, I know of one guy (Francis) who got fed up with the air leaks, disconnected all air from the door cylinders, capped off the air supply, and installed a 12v electric actuator with a switch. He loves it.

Bear with me I'm a rookie.

Can't get the air fittings off after soaking with wd40.

What do you recommend? Anything other than wd40?

Are you trying to remove the adjustment fittings, not the supply? If you use a 6 point socket you should be able to get the fittings out. If necessary a heat gun could be used but not a torch as there is rubber in there.

I was trying to remove all fittings to clean. I assume if that doesn't work I will have to use these fittings on the new valve.

The supply fittings are a standard item that can be bought many places.

It'll take a bit of torque to break the sealant but then they'll come out pretty easily using either a socket or tubing wrench or even an open end wrench if it will fit. Better not to use an open end or crescent wrench since the brass is pretty soft and easy to round off. Use a wire brush to clean off the old sealant, reapply new ptfe sealant when re-installing.

Tommy,
The valve sounds like it's just gummed up. Try freeing it up with some light weight oil down each port opening. These are piloted valves so it needs pressure for the spindle inside to actually move.
Here's an old link to a similar post:

What about that kind of relief valve? What is that style relief valve called? In case I break one like I already did😳

Is this a suitable replacement

Or is there a source for the same one?
