Samsung refrigerator defrost heater helps:

To test your defrost heater, you will need to unplug the refrigerator or freezer and disconnect the wires to the defrost heater.

Before you can test the defrost heater you will need to unplug the refrigerator freezer and disconnect the wires going to the defrost heater. To test the defrost heater you will need to use a multimeter to do an ohm test.

If you have an "auto-ranging" multimeter, then turn it to the home setting. If you have a "manual ranging" multimeter, then you will need to set it to the lowest ohm setting.

Place one of each of the probes on each of the heaters, wires or terminals.

You should get an approximate reading of 10 to 150 ohms, depending on the defrost heater.

If the display on the meter does not change or if your reading is far off from the 10 to 150 ohms, then you probably have a bad defrost heater.

Some defrost heaters have an defrost thermostat built into the wiring for the defrost heater. Example: Defrost Heater with Defrost Thermostat Picture. You will need to make sure the defrost thermostat is cold before you can test the defrost heater.
