Samsung Refrigerator Error Code Freezer 2nd digit g

This code indicates a freezer defrost system error. It is triggered when the defrost heater runs for more than 80 minutes without being shut down by the thermistor, or when the control board detects a fault such as a short circuit, open circuit, cut wire, or disconnected connector in the defrost circuit. The first diagnostic step is to measure resistance across the purple and white wire terminals of the defrost heater: 0 ohms indicates a heater short, and infinite resistance points to a cut wire or blown thermistor.

Continuing to use the refrigerator with this error active is not recommended for the long term. Without a functioning defrost cycle, frost will accumulate on the evaporator coils and block airflow, causing the freezer to lose cooling capacity and potentially damaging stored food. Addressing the fault promptly prevents further problems.

Repair costs depend on which component has failed. A defrost thermistor typically costs between $10 and $40 for the part, while a defrost heater assembly may range from $30 to $90. If professional labor is required, total repair costs including parts and service can range from $100 to $300 or more depending on your location and the specific components involved.

A knowledgeable DIYer can diagnose this fault using a multimeter to check resistance at the defrost heater terminals. Reconnecting a loose connector or replacing an accessible defrost heater or thermistor is within reach for someone comfortable working with appliance wiring. However, if the fault involves damaged wiring inside the freezer walls or a control board issue, professional service is recommended.

A reset may temporarily clear the error code from the display, but the code will return if the underlying defrost circuit fault has not been repaired. The 80-minute defrost timeout or the electrical fault condition will simply trigger the code again during the next defrost cycle. Repair the root cause before relying on a reset.
