If you set a house rule setting the expectation of him keeping his bedroom tidy, Goodtimer can stay on and he can earn Good Time when he makes good choices for cleaning up his room.  If your child refuses to clean up his room, an appropriate consequence would be to tell him to flip his Goodtimer over and tell him he is unable to earn Good Time until the job is done.  Once the room is clean, tell him the Goodtimer can be flipped back over and he can continue to earn Good Time.  It is very impactful if a child realizes that making the good choice is linked to incentives he wants.
