Electrolux Oven Error Code EtUC

EtUC indicates that the oven's cavity temperature exceeded the over-temperature limit detected by the TCAV sensor, causing the control board to stop the active cycle. This is a protective shutdown to prevent damage to the oven or its components. The most common causes are a dirty oven cavity or a cavity over-temperature parameter (COT) that is set too low. Addressing either of those issues typically resolves the error.

Yes, EtUC is a safety-related code because it signals that the oven cavity reached a temperature beyond its acceptable limit. The oven stops the cycle automatically to protect itself and its surroundings. You should not attempt to restart and continue cooking until the underlying cause, such as a dirty cavity or an incorrect temperature threshold, has been identified and corrected.

If the fix is simply cleaning the oven cavity or adjusting a configuration parameter, costs may be minimal or limited to a service call fee, typically in the range of $75 to $150. If the TCAV sensor requires replacement, parts and labor combined could run between $150 and $350 depending on the technician and part availability. Control board replacement, if needed, is the most expensive scenario and can range from $300 to $600 or more.

Start by opening the oven door or running a cooling cycle to bring the cavity temperature down. Once the oven is cool, clean the interior thoroughly to remove any grease or food residue. After cleaning, check that the TCAV sensor is properly positioned and producing accurate readings. If the error continues, a technician should review the COT parameter setting in the service configuration and adjust it to the correct value.

Resetting the oven may clear the error code temporarily, but if the root cause is not addressed, the code will return. A dirty cavity or a misconfigured COT parameter will continue to trigger EtUC on subsequent cycles. Always resolve the underlying issue before relying on a reset to restore normal operation.
