Electrolux Oven Error Code FU17

FU17 indicates an open circuit has been detected in the outgoing phases of the upper inverter. This means the electrical circuit carrying power out of the inverter to connected oven components is broken or not completing properly. The oven stops operation when this fault is detected. The most common cause is a loose or unplugged connector at the inverter.

No. When FU17 is triggered, the oven stops operation automatically, and you should not attempt to bypass or ignore this fault. An open circuit in the inverter's outgoing phases can indicate a wiring or component failure that could pose a risk if the oven were forced to run. Keep the oven powered down until the fault is properly diagnosed and repaired.

If the fix is a reseated connector, there may be no parts cost, though a service call fee typically ranges from $75 to $150. If the wiring harness needs repair or replacement, expect parts and labor to fall in the $100 to $300 range. A failed inverter board is the most expensive scenario, with total repair costs potentially ranging from $200 to $500 or more depending on the specific board and local labor rates.

If the cause is simply a loose connector at the upper inverter, you may be able to resolve it by locating the inverter, checking that all outgoing phase connectors are fully seated, and restarting the oven. However, if the fault involves a damaged wiring harness or a failed inverter board, those repairs require more technical skill and replacement parts. Always disconnect power to the oven before inspecting any internal components.

Resetting the oven by cutting power may temporarily clear the fault display, but the code will return if the underlying issue has not been corrected. A reset is not a fix. The open circuit condition in the inverter's outgoing phases must be identified and resolved for the error to clear permanently.
