you shouldn't have to jump the door switch...just check it for continuity w/ the door shut. If that checks good, Test the Thermal Fuse. If its blown the machine will not work at all. The reason the Thermal Fuse blows is because of poor airflow which causes the machine to overheat and once the machine gets over a certian temp at that fuse it blows so you dont burn down your house.
(I change alot of them) If it is blown change the part, then clean your entire dryer duct. One other thing to check is to make sure you have 240 volts @ your cord. You could have a bad breaker, terminal block, cord, or recepticial.
