dryer jfrigidaireust stoped running

i have a combination washer dryer,appartment size, and the dryer was working just fine, then just stoped for no known reason to me. could any one give me some where to start checking. I am thinking it is the thermal limiter from what i have read but what is the best way to get it if it is in a sm. closets. or what would you check first. thanx wm.
