Brian for Model Number RS2545SH Freezer side works fine. Fridge side hovers around 55 deg F. Ice all over the coils. Fan blows fine when I hold the door switch close to test it. Took a multimeter to the thermal fuse and temperature sensor. Thermal fuse read 4.26K ohms, and temperature sensor read 4.22K ohms (ambient temperature around 80 deg F). Took the multimeter to the defrost heater and it read open. That's my problem right? Any way to test it besides the plug (i.e. bare wires/metal along it?)? Any way to test the control board to ensure that's not also broken?
Answer Brian, With the heater not having continuity then it would be faulty and would need to be replaced. If you have a calrod heater in your unit then you would need part number DA47-00322H. If the heater is built into the evaporator then you will need a evaporator assembly DA59-00234H. Read More... Answered by AppliancePartsPros.com | Thursday, April 7, 2016
