Electrolux Professional FU13

What does Electrolux Professional FU13 mean?

FU13 means the SkyLine oven has a communication error with the upper cavity motor inverter, and the appliance stops. It corresponds to the N°201 upper-inverter communication problem. The control cannot talk to the inverter, typically because of a missing inverter power supply, an unplugged or damaged connector, or a blown fuse.

Symptoms

• FU13 displayed and the appliance stops
• No communication with the upper inverter
• Upper cavity motor not driven
• May follow a power or wiring disturbance

Common causes

• Inverter power supply (AC) missing
• Connector unplugged or damaged
• Fuse F2 blown

Diagnostic steps

1. 01

   Restart the oven

   Restart the oven, as the manual's first action.

2. 02

   Watch for recurrence

   If the causes persist, the error will appear again, pointing to a real wiring or power fault.

3. 03

   Note the likely causes

   A missing inverter AC supply, an unplugged/damaged connector, or a blown F2 fuse are the documented causes.

4. 04

   Call Service if it persists

   If the causes persist, call Service to inspect the inverter wiring and fuse.

When to call a professional

Restart once; if FU13 persists, call an Electrolux Professional engineer. A missing inverter supply, a damaged connector, or a blown F2 fuse are internal electrical faults requiring trained diagnosis and parts. Working inside the inverter and fuse area involves mains-level wiring, so do not attempt it as kitchen staff; a technician must restore communication with the upper motor inverter.
