I can't think of anything it would do then. It does just seem a waste of energy.  Does anyone else know of a reason to keep it on?

The ones I've dealt with aren't even that useful for grease - the fans appear too weak & don't suck in the exhaust, so every time I fry meat I end up with droplets of grease all over my stove - and me (as I can tell from my glasses).
