After calling a repair person and after two visits, he was unable to fix the problem. Not to mention we paid over $120 for his expertise. How disappointing. We will never call them again. We went online and after a couple of utube videos my husband figured out what was needed. We ordered the parts from appliance parts pros and they arrived within 24 hours. My husband installed the parts and our refrigerator is working better than before. We thank you because you saved us from spending money on a new refrigerator. The parts we ordered was evaporator coil heater and a thermostat.
