Frigidaire Refrigerator Error Code E2

The E2 code means the refrigerator has detected a failure in the freezer compartment temperature sensor, also called the F room sensor. The control board is either receiving a signal outside the expected range or no signal at all from this sensor. The fault is associated with the sensor terminals at connector CN1. The refrigerator may not regulate freezer temperature correctly while this code is active.

It is not recommended to rely on the refrigerator for food storage while E2 is active. Because the control board cannot accurately read freezer temperature, it may not run the compressor correctly, which can lead to inadequate cooling. Perishable foods in the freezer could thaw without any obvious warning. Address the fault as soon as possible to avoid food spoilage.

A reset may temporarily clear the E2 code by cutting power to the control board, but the code will return if the underlying issue with the F room sensor or CN1 connector has not been resolved. Unplugging the unit for a few minutes and restoring power is a reasonable first step to see if the fault was a temporary glitch, but a persistent E2 code requires physical inspection and testing of the sensor circuit.

In many cases, yes. Start by unplugging the refrigerator and locating the F room sensor connector at CN1. Inspect the connection for looseness, bent pins, or corrosion and reseat it firmly. If the connection is solid, use a multimeter to test the sensor resistance. A reading that is open or shorted confirms the thermistor needs to be replaced, which is a straightforward repair for someone comfortable working with appliance components.

If the fix is simply reseating a loose connector, there is no parts cost involved. Replacing the F room thermistor sensor typically runs between $15 and $50 for the part, depending on the model. If a technician is needed for diagnosis and repair, expect total costs in the range of $100 to $250, including labor. A control board replacement, if required, can push costs higher.
