Product review (5 stars): back again
2/1/14
A previous replacement lasted for two years so I am trying out this particular supplier.  This looks promising as the item arrived promptly using regular shipping with packaging and instructions.

I repeat my tip below so you do not have to hunt for it:

[Be safe, unplug the dryer and] diagnose each sensor and the heating element by disconnecting one lead and checking for continuity with an ohm meter.
For us, the wires were all red and so it might behoove you to tag the wires to avoid mixing them up during reassembly.

For the particular model LC9480XWN1 Whirlpool dryer we have, there is a single screw at the top of the cover tube for the heating element that is accessible through a hole in the top back panel of the dryer.  The entire cover tube pops backward and then slides up.  [At the time, none of my search hits provided this tidbit of information on how to access and remove the heating element cover tube.]
