Customer Questions and Answers for Refrigerator Door Switch by Lg

Blaine, there are several factors that can cause a door switch 6600JB1010A to fail. If there is a loose terminal connection, it can create arcing and cause the switch connection to not be able to pass voltage through properly. If a refrigerator door is opened and closed frequently throughout the day, it can cause more wear to occur on the contacts inside of the switch. Another possibility would be if the door does not fully press the switch in, which can cause arcing between the contacts and stop them from operating properly.
