Product review (4 stars): Worked well.
Apparently the thermistor is a common problem with the LG washer I have.  The videos I used to replace it had it in the front of my machine and it took a far amount of work to open the front up.  One screw was badly placed and I had to find a special screwdriver to get a good angle on it.  After all that work, it turned out that the thermistor was in the back - 4 screws to take off the back plate, replaced the thermistor and the washer has been working ever since.  Definitely happy with the new part.
