Product review (5 stars): Hall Sensor 2002A/2002J Fixed LE Error Code on LG Washer
I purchased this because my LG WM2277HW was getting the LE error code just a few minutes into a cycle and it would not clear by unplugging the machine and pressing the Start/Pause button for 5 seconds as suggested. There are really only 4 things that can cause the LE error according to a web search:
1. Clogged up machine from too much soap or other residue.
2. Bad Rotor Position (Hall) Sensor.
3. Bad wiring harness.
4. Bad circuit board.

My LG uses the 2002A sensor. This looks slightly different in the picture in that it has 2 inner tabs instead of only one like the original 2002A on my LG (see attached photo - new 2002J on left, old 2002A on right). This sensor was factory packed in a bubble wrap package and the sticker on the package says 2002A, but the sticker on the sensor inside the package says 2002J. From doing some reading It appears the 2002J is a recent replacement for the 2002A. I installed it and no longer get the LE error code. Easy cheap fix.
