Refrigerator is clicking, won't run
Is this clicking happening about every three or four minutes?
It sounds like the klixon, which is a thermal/current sensing device which is under the electrics cover on the compressor. It is a metalic disc which if the current is too high, or the compressor case temperature too hot, will cause the disc to expand and will move from being convex to concave in shape. As it moves from one to the other, it makes a clicking sound. The usual cause of a cycling klixon is lack of refrigerant in the system which causes the compressor motor to cease which means when it tries to start the current rises too high and the klixon 'pops' which breaks the contact. It cools down, 'pops' again, makes the contact, tries to start, won't because it is seized, current rises, klixon pops out again, and so on. You need to get a qualified refrigeration engineer in to fix it, or if it is an old unit, bin it and buy a new one.
