Order part at appliancepartspros.com *( Heater and Thermal Assy. ) and with that I watch a video on how to repair my fridge. It took me about 15 minutes to replace the parts. I think it took me longer than that to watch the video itself because I want to make sure that I will do it right. Replacing a part is very easy, now after two weeks my refrigerator is running good so far !!!!
