I haven't been able to create a useful search, so I have to ask. What are the most likely causes that the ice door would only snap open part way (3/8")? I can raise it open fully with no trouble while holding the switch in, and it stays up until I release the switch, then it returns not opening fully again. Is this the solenoid, and can it be replaced from the front without removing the interior liner? Also, what is the current part number, for the actuator? Thanks.
