Thor Kitchen Refrigerator Error Code E2

E2 on a Thor Kitchen refrigerator indicates a freezer compartment sensor error. The control board has detected that the sensor is reading below -50°C (-58°F), which points to an open circuit, or above 50°C (122°F), which points to a short circuit. Neither temperature is physically possible under normal freezer operation, so the error always indicates an electrical fault with the sensor or its wiring rather than an actual temperature problem.

It is not recommended to continue relying on the refrigerator for food storage while E2 is active. Without a functioning freezer sensor, the control board cannot accurately regulate the compressor, which means the freezer may not maintain safe temperatures. Food in the freezer could partially thaw or the unit could run continuously, risking further component damage.

If only the freezer temperature sensor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model. If you hire a technician to diagnose and replace the sensor, total repair costs including labor generally fall between $100 and $250. Control board replacement, if required, is a more expensive repair and can range from $200 to $400 or more for parts and labor combined.

In many cases, yes. Start by unplugging the refrigerator and inspecting the freezer sensor wiring and connector for loose connections, visible damage, or corrosion. If connections are secure and wiring looks intact, use a multimeter to test the sensor resistance. A sensor that reads open or near-zero ohms needs to be replaced, which is a straightforward repair for anyone comfortable working with appliance wiring and basic electrical testing.

A power reset by unplugging the unit for several minutes may temporarily clear the E2 display, but the error will return if the underlying sensor or wiring fault has not been repaired. A reset does not fix a failed sensor or a broken wire. The fault must be diagnosed and corrected for the error to stay cleared.
