Check for krausen. You might not even need to open the fermenter. A strong light on the backside should show through enough to see the level of the wort and any krausen above that line. If not, sure, open it up to see. If there is no krausen, add yeast. If you have evidence of krausen, take a gravity sample while you have the fermenter open.
