I have an LG refrigerator model number LRSC26940SB few years ago. Recently, he tapped (about 8 of them, evenly PACE), which occurs every 15 minutes or so. . There must be some kind of mechanical failure or reset, or a change of the indicator, someone can help me?

I’m having trouble finding seats, refrigerator Samsung HTE with ice and water in the door. I know Lowes, and best buy, they can order, but they are not available within 100 miles, and they say that it will take several weeks to get in. I need this Friday. Anyone know of any retailers that Carrie this, please let me know.
