I have a semi operating step cover.. I know I have to work on it, but for the life of me cannot find where the mechanism is! Newell told me it was under the sink cabinet false bottom. I removed the bottom and all that is there is the heat exhanger and fan... I have a feeling it's leaking as well....

My coach is "backwards" the kitchen is on the Driver's side....

I have a similar layout as you.  I checked under the false panel under the kitchen sink and also have a heater.  Did you ever find the mechanism, and how do you get to it?  I here a solenoid click, but the slide does not move.  By hand, the slide moves easily.  Thanks
