Frigidaire Refrigerator Error Code 2

Error code 2 on a Frigidaire refrigerator means the control board detected an open circuit on a thermistor, either the freezer thermistor or the food compartment thermistor, during startup self-test or service diagnostics. An open thermistor means the temperature sensor is not sending any resistance signal to the control board. This is typically caused by a broken wire, loose connector, or a failed sensor.

The error code itself does not represent a safety hazard, but it does mean the refrigerator may not be accurately monitoring or maintaining the correct temperature in the affected compartment. Food safety can become a concern if the fridge or freezer is not holding proper temperatures as a result of the fault. Address the code promptly to ensure the appliance is operating correctly.

If only the thermistor sensor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model. If a wiring harness repair or connector replacement is also needed, that may add to parts costs. Professional labor for this type of repair generally runs in the range of $100 to $200 total, though costs vary by region and service provider.

In many cases, yes. Start by unplugging the refrigerator and inspecting the thermistor wiring harness and connectors for loose, corroded, or broken connections. If the wiring checks out, use a multimeter to test the thermistor resistance. If the sensor reads open, replacing the thermistor is a straightforward repair that most technicians and experienced DIYers can perform without specialized tools.

A power reset may temporarily clear the error code from the display, but if the underlying cause, such as a failed thermistor or broken wire, is not repaired, the code will return during the next self-test or diagnostic cycle. A reset should be used only as a diagnostic step to confirm whether the fault is intermittent, not as a permanent fix.
