Product review (4 stars): Works well, saved me over 200 dollars
Local service person wanted 240 to replace part,  With the help of youtube and the wiring diagram (usaually under top panel) was able to switch part and 155 deg sensor in 20 minutes with everything.  Very simple repair.  Dryer essentially a larger toaster with a fan and turning drum.  This is the heater coil (toaster part).  Some units have four screws some have two.  Swap out one module from old to new (does not come with it) and you are ready to go.  Received in 3 days with expedited, was not available for Prime.
