I have a LG model GR-L206CVQA fridge freezer and the display locks up and the dispenser that should provide crushed ice or chilled water or cube ice is stuck on crushed ice only. Sometimes there is a whiring sound and the display, dispenser and temp set point adjust works as it should but after 20 minutes or so it goes back to the locked position for a day or so.
