Frigidaire refrigerator constantly freezing and then thawing

I have a Frigidaire FFTR1821QB0 freezer on top refrigerator. A couple of weeks ago, it got extremely warm in both the refrigerator and the freezer. It looked like the evaporator froze over. Eventually it started cooling again but this has happened multiple times over the last week. I adjusted the controls so that it was on the recommended temperature in each compartment and I have now replaced the wire harness with the defrost sensor and the thermistor. It seemed to be working fine for a few days but it has started having problems again. Is there anything besides the control board that could be causing this problem?
