Electrolux Oven Error Code FU6

FU6 indicates that the upper inverter, the electronic module that drives the convection motor, has been detected at a temperature above 100 degrees Celsius by its onboard sensor. The oven triggers this code to protect the inverter from heat damage. Root causes include blocked air filters, motor fan friction, or an incorrectly configured motor parameter (parameter 198).

No, you should not continue using the oven while FU6 is active. The code indicates the inverter has reached a temperature that exceeds its safe limit, and continued operation risks permanent damage to the inverter module and potentially the motor. Stop using the appliance and allow it to cool completely before beginning any diagnosis.

Repair cost depends heavily on the root cause. A filter cleaning costs nothing beyond your time, while a service call to diagnose and correct parameter settings typically runs in the range of $100 to $200 for labor. Replacing a faulty convection motor fan assembly can add $50 to $150 in parts, and an inverter board replacement, if required, generally costs between $150 and $400 or more depending on the model. Getting a diagnostic estimate before authorizing repairs is recommended.

Some causes of FU6 are DIY-friendly. Cleaning the air inlet filter and visually inspecting the convection fan for obstructions or binding are reasonable first steps that do not require special tools. However, checking or adjusting parameter 198 requires service-level access to the oven control system, and replacing an inverter board involves working with electronic components at potentially hazardous voltage levels, so those steps are best handled by a qualified technician.

A power reset may temporarily clear the FU6 code if the inverter has cooled back below the threshold, but the error will return if the underlying cause is not corrected. If the filter is clogged, the fan is binding, or parameter 198 is wrong, the inverter will overheat again during operation and re-trigger the fault. Always address the root cause rather than relying on resets.
