How to Troubleshoot & Replace Whirlpool AP6007561 / WP306604 Thermal Fuse

Just buying more stuff from appliancepartspros.com 

I went through the machine testing for continuity until I located and could confirm that the gas igniter was faulty. I then replaced it with a 1/4 inch box wrench not completely removing the screw but just getting it to the point I could take it off and put it back on. I then went about replacing the coils which seemed to be tired and the blower thermostat. I didn't replace the fuse or the flame sensor because they were still working. Now the dryer does a better job faster than before. I bought all these parts for at least half the price of a visit from a tech and got the job done in a timely fashion. The hardest part was figuring out how to take the front of the dryer off so I could get to the parts. This involed two srcews at the bottom and 4 inside. 

Research showed me four main parts that can wear out over time or start malfunctioning. First replaced the Igniter - still got same problem. Then ordered three other most likely parts from AppliancePartsProscom - i ordered the Thermal Fuse, Cycling Thermostat, and the Gas Solenoid coils (its a set of two round parts). The parts avg bout 15 bucks on this website so rather than test i figured i would just replace them because of their age so that I could bring my machine to a newer state. Success ! I dont know which of the three did the trick but my dryer is running like new and it runs better than before, it has better heat and everything is coming out completely dry just like a new dryer. Thanks AppliancePartsPros for the parts which are sold at a very reasonable price and also the tech videos are very helpful as well. Btw the igniter was from a local distributor and that alone cost 35 bucks, not sure if APP could have provided the part for less cost.
