Steven R Amarillo , TX May 08, 2018 Appliance: Model WM2487HRM (ACREEUS) Te error code. The problem could be the thermistor or the heating element so I replaced both. One thing I learned was that the thermistor was the correct part number, but the heating element wasn’t. LG upgraded the heating element and I had to confirm they were comparable through LG.
