Dryer wouldn't heat

I attempted to take the back panel off the dryer only to discover all I had to do (after removing 10 or so screws) is remove the lower base plate in the front of the dryer. I also had removed the door which turned out to be unnecessary. After removing a guard in front of the heating element (2 screws) I yanked the the element housing that contained the heating element and then disconnected the 6 wires. Using my first ever, newly bought multi meter for only $9.99 from Radio Shack, I turned the dial to the infinity section and check the element for continuency. I did this by touching the meter's two probes to the element's terminals were the wires connect. The element was fine. Then I checked the two sensors the same way. The sensor furtherest away from the element's terminals didn't have a constant signal so I assumed that that sensor was bad. Well, come to find out, one sensor is open and the other in closed... only when the temp. changes do they operate by opening and closing the current. By this time I had already ordered the part so it was too late. Surprisingly, the part came in 2 days. I ordered it Sunday night and i figured it would be sent out Monday but it was already in the air Monday morning... Great service! I replaced both sensors and the dryer works like it did when I first got it.
