I have a sliding french door that is becoming very hard to open and close. I guess there are some rollers under it that need lubrication, but I can't see how to remove the door so that I can get to them. Is there a common method for doing this?

Your sliding door is on rollers as you say - but maybe, before you get in there with some WD40, just check that the door isn't scraping along its track. If it is, you can lift the doors a fraction by putting a screwdriver in the access holes at the bottom of the door frame and turning the adjustment mechanism until the door slides free.
