What this part does - The WR9X355 is a refrigerator cold control thermostat used as a sensor in fridge units and freezers. - It senses temperature changes in the evaporator during the defrost cycle and turns off when ice has melted, helping regulate cooling. Replaces the following part numbers - 310779, AP2061636, PS310768, WR09X0223, WR09X0239, WR09X0245, WR09X0246, WR09X0248, WR09X0252, WR09X0257, WR09X0279, WR09X0286, WR09X0299, WR09X0333, WR09X0343, WR09X0353, WR09X0355, WR09X0357, WR09X0360, WR9X223. Product specifications - PART NUMBER: WR9X355 - Electrical ratings: 12/6 FLA; 60/30 LRA - Voltage: 120/240 VAC Symptoms this thermostat fixes - Fridge section is too cold - Freezer section is too warm - Freezer section is too cold - Will not start - Frost build up Use scenarios - Scenario 1: A GE refrigerator experiences frost build up and inconsistent freezing. Replacing the faulty thermostat with WR9X355 helps restore proper defrost control and temperature regulation. - Scenario 2: The freezer is running too warm or too cold due to a degraded sensor. Installing the WR9X355 can stabilize freezer temperatures and improve overall freezer performance. - Scenario 3: The appliance exhibits startup or cycling issues related to the evaporator sensor. Replacing with WR9X355 can resolve defrost cycle timing and restore normal operation.
