Common Symptoms That Indicate Replacement Is Needed
-
Frost or ice build-up visible on the evaporator coil (behind freezer liner) despite the system running. Repair Clinic
-
Freezer is excessively cold while the fresh-food compartment is warm, or the refrigerator runs continuously without reaching proper temperature.
-
The defrost heater is energized but the coil remains icy long after the defrost cycle.
-
Water pooling under the freezer or refrigerator because melt water is not draining due to ice blockage.
-
Thermostat tests as open (no continuity) at ambient moderate temperature—should be closed at room temperature for this style.
Compatibility Notes
-
Confirm your refrigerator’s model number, existing thermostat part number and evaporator coil style to verify WR50X10010 is correct—this ensures correct temperature rating, clip size, and mount style. geappliances.com+1

While replacing the thermostat may eliminate defrost cycle failures, if other components (defrost heater, defrost timer/control board, drain system) are faulty the symptoms may persist. A technician check is advised.
-
Disconnect the appliance from power before servicing to avoid electrical hazard.
-
Because this part involves internal refrigerator components, professional/technician assistance is recommended for correct installation and safety.
