Dryer does not work on medium heat setting

My Whirlpool electric dryer heats on high heat setting but not on medium. We cleaned the vents out, which were not clogged but still not working. What else can we check?

ok, I will get it tonight and post it tomorrow. someone told me it is probably the timer and if that is the case they are about $200 and would be better off to just buy a new dryer. do not really want to do that.

I do have the mod and ser #'s. DWSR483EB0WW DF712663A
