The dryer would ignite once or twice then cut out. The motor worked & the sensor were testing correctly. A week of researching it, less if the sites were better organization like a flow chart (if this then that etc.) very frustrating. A multimeter is the only way to be sure, a part is malfunctioning both continuity and voltage & I did not want too test voltage but going slowly it worked fine. I then gave my findings to the "tech support" & she earnestly discussed my conclusions based on their data. By the time I made a purchase (a few minutes) I was certain of what I needed and it wasn't a repairman or person whatever. The parts ($40 worth) fit just right, note: use a screw driver to release any contacts not a pair of plyers. I pulled a contact wire off testing it & one of the edges of the dryer cut into all my fingers. Septic powder, couple of bandages, & a tight plastic glove for direct pressure stopped the bleeding, (lack of patience). There were no other problems other then my carelessness. Then dryer & my wife fired right up perfectly. Knowing that my purchase was refundable is a great help when working on something a week earlier I knew nothing about. I learned allot for the next home repair job. Thanks
