Frigidaire Refrigerator Error Code t1

The T1 code means the freezer temperature sensor has been detected as open or shorted by the control board. This sensor, called a thermistor, monitors the freezer compartment temperature so the refrigerator can regulate compressor and fan operation. When the sensor's resistance is out of range, the board flags the T1 fault. The issue can be a failed sensor, a loose connector, or damaged wiring.

The T1 error means the control board cannot accurately read the freezer temperature, which can cause irregular compressor cycling and potentially inadequate cooling. You should use a standalone freezer thermometer to verify that the freezer temperature is staying at or below 0 degrees Fahrenheit. If temperatures are rising above safe levels, transfer frozen food to another freezer until the repair is completed.

If only the freezer thermistor needs replacement, the part typically costs between $10 and $40 depending on the specific model. If professional labor is involved, total repair costs can range from $100 to $250 including the part and service call. A control board replacement, if ultimately needed, will cost significantly more and should only be pursued after confirming the sensor and wiring are not the source of the fault.

A knowledgeable DIYer can often resolve this error by inspecting and reseating the thermistor connector or replacing the thermistor itself. The sensor is typically accessible inside the freezer compartment and replacement involves disconnecting the old sensor and plugging in a new one. Testing the sensor with a multimeter before purchasing parts can help confirm whether replacement is needed.

Unplugging the refrigerator for a few minutes and restoring power may temporarily clear the code, but the T1 error will return if the underlying sensor or wiring issue has not been repaired. A reset alone does not fix a failed thermistor or a wiring fault. The code will clear permanently only after the defective component is repaired or replaced.
