Product review (5 stars): Replaced is less time than waiting on service guy.. assuming service guy fixes it. Solves LG Tromm "tE" error message.
I called an appliance service company, waited five days for them to come out, $95 for the call and the first 30 min of labor. I got scheduled for the first call of the day so there would be no delays. Of course, the guy calls 20 minutes late to tell me he's going to be late.  Shows up 45 minutes late, takes the washing machine apart, says I need a wiring harness.  Makes a call to the parts company, says he'll call me in a couple hours with the repair cost.  Tomorrow will be a week, still no call.  And laundry is piling up.  Anyway, diagnosed the problem via internet, had this overnighted from Amazon, and 45 minutes later the machine is working again.  This was for an LG Tromm front loading machine.  I would rate my fix-it skill at advanced, and this repair easy to moderately difficult.  The only real challenge is having to remove the front of the machine to get to the bottom of the drum.  That itself is simple, but re-installing the door seal isn't easy. There is a large spring mechanism that holds it in place and this isn't easy to manipulate back into place. My recommendation would be to spend 30 minutes or so online and reviewing the steps to get there, and the screws that need to be removed. Save your parts in order that they came off and don't let your wife/dog/kids near the job until you're done.  Note that I was getting the "tE" error message on my LG machine, which corresponded to bad thermistor though many with the same error message reported a broken lead wire to the thermistor.
