Frigidaire Refrigerator Error Code 41

Error code 41 on a Frigidaire refrigerator means the freezer temperature sensor (thermistor) has an open circuit. The control board is not receiving a resistance signal from the sensor, so it cannot monitor the freezer temperature. This can affect cooling performance and will need to be diagnosed by checking the sensor, wiring, and connectors.

Running the refrigerator with an active error code 41 means the control board is operating without accurate freezer temperature data, which can result in inconsistent cooling or temperature swings. Food safety could be compromised if the freezer fails to maintain proper temperatures. It is best to address the issue promptly rather than continue using the appliance in this condition.

A reset may temporarily clear the error code from the display, but if the underlying cause, such as a failed thermistor or broken wire, is still present, the code will return. Resetting alone does not repair the open circuit condition. The fault must be diagnosed and corrected for the error to clear permanently.

A knowledgeable DIYer can inspect the wiring and connectors for obvious disconnections or damage, which sometimes resolves the code without part replacement. If the thermistor itself has failed, replacing it is a moderately straightforward repair that involves removing the freezer interior panels to access the sensor. Testing the thermistor with a multimeter is the best way to confirm whether the sensor or wiring is at fault before purchasing parts.

If only the freezer thermistor needs replacement, parts typically cost between $15 and $50, and the total repair with labor can range from $100 to $200. If the main control board is the cause, parts alone can range from $100 to $300, with total repair costs potentially reaching $250 to $450 depending on labor rates in your area.
