Product review (4 stars): "te" error fixer
If your LG Tromm washer has the "te" code, this is the fix. Don't pay big bucks for a repairman, this is a very easy fix, took me maybe 10 minutes. There is a video on youtube where a guy with a funny haircut shows you how to accomplish the repair. His way works, but involves a lot of dissassembly or the machine. I'm pretty good at taking things apart, not so good at putting things back together. My washer is on a pedastal, I just tipped it over sideways and laid the top of the washer on my garden hose reel and had easy access to the thermistor. Replacement was quick and easy, just had to clip a zip-tie to pull out old thermistor. The washer has worked flawlessly for over two weeks now, after several loads of laundry. This part came to me quickly as well.

Update 7/13/14: It's been three months now with the new thermistor, and everything still works great!
