I checked my defrost heater and found it has 21.8 ohms. I noticed that one of the wire terminals connecting to the heater burned out. Could it be the problem the heater although having coninuity is not working? Here is my problem: The entier evaporator is covered with ice. I have changed the two hermisters in the freezer and the main contorl board. The problem of warm refrigerator still exists. I have ordered the heater, but was wondering whether I also need to change the burned wire terminal.
ANSWER Hello Lillian. Yes, if the wire is burnt, you will need to repair the terminal on the wire as well.
