I have a LG fridge, it's been running erratic at times. I had noticed a clicking like a car's directional. I unplugged it and it's been running OK all day freezer is at 11 deg and the box is at 36 deg. the compressor is not hot at all. I took the cover off the back and notice a green light blinking on the PCB board. It's running fine now but concerned about it quitting and loosing my food. It's not clicking now and seems fine but the green light is flashing. any ideas.
