Product review (5 stars): Excellent buy!!!
I had a 14 years old Maytag gas dryer that would initially start OK, but after 5 minutes the flame would not kick in and the heat would not follow.  I changed the thermostats and fusible link after removing the back panel, but the problem persisted.  Figured it is with the sensors, igniter, solenoid coils or the solenoid valves.  Following guidance from youtube videos, I popped the cap on the front peep hole to notice that the igniter was still OK.  So decided to change the flame sensor ($11) and the coils ($3).  Both would have cost $20 each at a Sears parts store.  But Amazon had a very good price.  I requested expedited shipping ($15 charge) and received the parts in 4 days via. Express Mail.  The parts were exact match and work extremely well.  I am amazed at the range of appliance spare parts and the 3X-6X lower that Amazon offers.  Good Luck!
