I need to find out what the film title this is... Help?

I remember watching a film before, few years ago... About some lift
thing... And the people went into this white room, and there was a
trolley with a dead person covered up on it, white sheet on top, one
arm hanging out... Not so much a horror, think it could be a family
kind of horror film. I can't really say much else, because the film
has only just come to mind... But suggestions of what the film could
be like would help. Oh another thing... I think there was a black man
in the film... not being racist... And he was going round this house
thing...
