The refrigerator had the above code and when I check on YouTube, it explained that the defrosting was not working properly. It was taking more than 80 minutes to defrost. I ordered the Temperature Sensor first and it was not the issue. I also ordered the Defrost Temperature fuse or the Thermistor. I had to defrost the refrigerator first by using a portable heater to get it done quickly. (See Youtube on how to get to the Defrosting Unit inside the freezer). The Thermistor was the wrong part. I called the Partselect and explained that the part with the heating element is one piece. (Heating Coil Thermistor or Heating Coil). By replacing that piece solved the Error Code issue. I listened to Youtube for the instructions on how to replace the Heater Coil. So if you see the Error Code dH F, you need to replace the Heating Coil, which comes in
one piece and sits on the bottom of the Defrost Element.
