Electrolux Oven Error Code FU11

FU11 indicates an Upper Inverter Undervoltage AC fault. It means the oven's control system detected that the AC power supply voltage dropped below 155Vac at the upper inverter circuit. The oven shuts down automatically when this happens to protect internal components. The cause can be a blown F2 fuse inside the oven or an unstable external power supply.

Resetting the oven by cutting power at the breaker may temporarily clear the FU11 code, but the fault will return if the underlying cause has not been corrected. If the incoming voltage is still dropping below 155Vac or the F2 fuse is still blown, the oven will detect the condition again and shut down. A reset is only useful as a temporary step while diagnosing the root cause.

Repair costs vary depending on the cause. If only the F2 fuse needs replacement, parts and labor could range from roughly 75 to 150 dollars. If the inverter module itself has failed, parts alone can range from 150 to 400 dollars or more, plus labor. If the issue originates in your home's electrical supply, electrician fees add additional cost. Getting a diagnostic assessment from a certified technician is the best way to estimate the total repair cost.

Some steps, such as checking whether your home circuit is providing stable voltage or inspecting visible wiring connections, can be done by a knowledgeable homeowner. However, replacing the internal F2 fuse or the inverter module involves working inside a high-voltage appliance, which is best handled by a qualified appliance repair technician. If the issue is traced to home wiring or the electrical panel, a licensed electrician should be consulted.

No, the oven stops operation when FU11 is triggered, so cooking functions will not work in this state. Even if you find a way to momentarily reset it, operating the oven while the inverter is experiencing undervoltage could cause further damage to internal components. The fault condition should be fully diagnosed and corrected before returning the oven to regular use.
