Jason for Model Number RS264ABSH/XAA My evaporator coil on the fridge keeps freezing up. The evaporator fan is running fine. The refrigerator holds a constant 34° as set. Does this unit have a defrost heater and timer on the refrigerator side? If so do you carry those parts?
Answer Jason, the refrigerator evaporator is not going to have a defrost heater. The refrigerator side is going to only have two sensors that are responsible for sensing when the evaporator needs to be in a defrost state. However, they appear to only be available with the evaporator assembly itself [DA96-00020Q]. You may want to test the voltage going to the sensors as well as the resistance of the sensors. If the defrost sensor from cn30 pin 8 to pin 6 reads 0 ohms or 0L, then the sensor is bad. The resistance level of the sensor also depends on the temperature of the sensor itself. The defrost sensor should read more than 25.65 k ohms at normal temperatures of the evaporator. Read More... Answered by AppliancePartsPros.com | Monday, February 25, 2019
