What is the procedure for testing a refrigerator’s thermistor?

Testing a refrigerator’s thermistor involves a few steps. First, unplug the refrigerator to ensure safety. Then, locate the thermistor, which is typically found inside the refrigerator or freezer compartment. Disconnect the thermistor and use a multimeter to measure its resistance. The reading should align with the normal range for the refrigerator’s model. If the reading is outside this range, it indicates a malfunction, and the thermistor likely needs replacement. Conducting this test is a critical step in troubleshooting the H1 code issue.
