Refrigerator runs for about 3 minutes than starts ticking constant for the rest of time till it shuts off. Also it runs for 15 minutes and is off for 20. Is that normal? I bought it 3 years ago it had been sitting for about 6 months. Lady said it never ticked when she used it. It is a GE model TBX14SAZBRWH. Ticking notice comes from freezer portion upper part of frigerator.
