Thor Kitchen Refrigerator Error Code E1

E1 indicates a fault with the temperature sensor located in the R-compartment, which is the main fresh food section. The control board has detected a sensor reading either below -50°C (-58°F), signaling an open circuit, or above 50°C (122°F), signaling a short circuit. Both conditions mean the board cannot receive valid temperature data. The sensor, its wiring, or the connector between them is the most likely source of the problem.

A power reset by unplugging the unit for a few minutes may temporarily clear the code if the fault was caused by a momentary glitch or a connector that reseats itself. However, if the underlying cause is a failed sensor, damaged wire, or corroded connector, the E1 code will return as soon as the board attempts to read the sensor again. A reset alone is not a fix for a hardware fault.

If only the R-compartment sensor needs replacement, parts typically fall in the range of $15 to $60 depending on the specific model, making it one of the lower-cost refrigerator repairs when done as a DIY project. If professional labor is required, total costs including parts and service time generally range from $100 to $250. A control board replacement, if needed, would increase costs significantly, typically ranging from $200 to $400 or more for parts and labor combined.

Some causes of E1 are DIY-friendly, particularly reseating a loose connector or cleaning corroded terminals. If the sensor wiring and connectors check out, replacing the R-compartment thermistor is a moderate repair that involves accessing the sensor inside the fridge compartment, disconnecting the harness, and installing a new sensor. If the control board is implicated, board replacement is more complex and may warrant professional service.

When E1 is active, the refrigerator cannot accurately monitor the temperature in the fresh food section, which means cooling may be unreliable or absent. Food safety could be compromised if temperatures rise into the danger zone above 40°F (4°C). It is advisable to check the actual compartment temperature with a separate thermometer and limit the time food remains in the unit until the error is resolved.
