I have a two-year-old LG LFX25991ST french door refrigerator. The door flap for the ice chute no longer opens all the way when activated, causing ice to clog in the chute. I presume a gear is worn or perhaps the motor is tired, but I cannot figure out how to remove the dispenser control panel in order to assess the problem or replace parts. Anybody know how to get inside the thing? Thanks in advance for any advice.
