Suffolk Omni Step

My OmniStep will extend every time, but retraction requires many operations of the single button before the step is retracted enough to stop the buzzer. It will not retract when the engine is started. I have checked and lubricated the pivot points and the step is quite loose enough so I suspect an electrical problem. Could it be the control relay? I am not sure where this might be located as my AS Suffolk Manual does not give this detail and in any case the manual appears to be generic as some of the references in it Di not apply.

Could be a micro switch which has become slightly stuck.  Should be a wire leading to it

Welcome to the forum. Not sure if it’s the same as the step on our Rienza but as Gef said the micro switch on ours is the biggest source of problems. I moved it from the back of the step bracket to the front because it was directly in line with the rear wheel. It still plays up occasionally so I spray it with contact cleaner and then WD40. 
The relay to retract the step when the ignition is turned on is at the back of the fridge accessible via the vents on the outside. Not the best place being open to damp weather. 
As I said not quite the same generation of motorhome but it might help.

Our step is single and swings out and down. The step switch is mounted through the frame from within the motor cover so I think different to yours. I only have a single push button to operate which suggests there is a step relay..the fact that it works perfectly extending every time suggests that the step relay has a fault, especially as the engine start does not retract. However if the relay is located at the back of the fridge like yours, I am at least one step (sic) forward,!,

Hello Trunkles
We are having exactly the same problem on 2011 Suffolk, so I'd be interested to know if you find a solution.
I have no idea what a micro switch looks like, so, if someone could explain, describe it, I'll have a look at that.
thanks

Hi. I am a 2011 County Suffolk owner in Sussex and Warwickshire reaching out to Suffolk owners for our own forum and perhaps a meet up at some time. I am Gary, single, living in Sussex relocating soon to Warwickshire. My CountySuffolk is named 'Solly Moho' and enjoying ownership

I used to have a 61 plate Suffolk - great van.

However, you’ve tagged onto someone else's thread about a step problem so you may not get many responses to your request for social interaction.

Not sure what you mean by having your own forum. There are several one-model groups on Facebook, perhaps you could start a Suffolk group there but not sure how many members you'd get.
