MyCandy fridge freezer seems to be cycling on and off continuously, either ?

MyCandy fridge freezer seems to be cycling on and off continuously, either the green light is on-off and a clicking sound is constant,or the the orange light is on permanently, either way the appliance still seems to be working. It is about 5 years old but I do not have the model No. I have a small manual for it but no mention of model, but the instruction on trouble shooting advises contacting Candy if the yellow light remains 'ON'
