Jeff for Model Number RM255LASH I have a Samsung Refrigerator Model: RM255LASH. There is a loud fan noise coming from the freezer side in back of the Ice maker. It stops when you open either the main freezer door or refrigerator door. The freezer does not seem to be freezing like normal. Food at the top was starting to get soft and the water in the ice tray is not freezing completely. The noise is loudest when freezer door is open and you hold the door button in. I can hear it in back of ice maker. Was looking at the following part: Motor Part Number: AP4136543. Is this what I need? If so do I access it from inside the refrigerator in back of Ice maker assembly?
Answer Hi Jeff. Your fan part # DA31-00020E may not be the issue. From the sounds of all, you have a defrost issue. The evaporator coils heave completely blocked w/ice and the fan is overworking to keep cavity temperatures satisfied. The defrost thermostat sensor part # DA32-10105G should remain normally closed in the frozen temperatures so it can pass the 120 vac to the defrost heater part # DA97-03153W. It only comes w/ the evaporator assy. It will be available on Mar. 5-15th. You can use the new heater and place it on the original coils so you do not need a complete sealed system repair just to use the new heater. Use a volt/ohm meter part # MA-DM1 to assist yourself in diagnostics. Make sure the inside cover styrofoam seals perfectly so the air flow will be normal. It needs to completely seal against the back wall the full circumference. Thank You. Read More... Answered by AppliancePartsPros.com | Monday, March 5, 2012
