roper dryer wont turn on,model#red444ovq1?

my dryer turned off mid cycle ,i restarted it twice ran for 5 minutes shut back off, now it wont run at all,i tested the thermal fuse it has continuity, i tested the start switch it has continuity when pushed,i tested the door switch,it had continuity when closed ,i tested the timer switch by pulling the power wire off the prong ,touching the power prong with one end and touching another prong with the other end using the meter, i had continuity, (i dont know if i checked the timer correctly),im searching for more stuff to test, but dont know what to test, any help would be greatly appreciated,thank you in advance.
