I left it out and plugged it in and ran it a few minutes and it seemed OK. Wiped it off again, replaced and we will see how it goes but it is working.

Note, never never shoot WD 40 in to a hot /live electrical device as the propellant is flammable. I am sure the WD 40 itself is flammable too so that is why I wiped off as much as I could.

That's great that lubricating it helped. For future reference WD40 should not be used on anything plastic. You should use a silicone lubricant when plastic is involved.
