Oven display shows E7, fan may run intermittently, heating disabled

Safety first: Disconnect mains power. Ensure the oven is cool before accessing the fan area.

• Access cooling fan: Remove the top cover or rear panel to reach the cooling fan assembly (not the convection fan inside the cavity).
• Check for obstruction: Inspect the fan blades for insulation, wiring, or debris preventing rotation. Remove any obstruction and ensure the blades spin freely by hand.
• Test motor: With power off, disconnect the fan motor leads and measure resistance. An open circuit indicates a failed motor.
• Inspect thermal fuse (if fitted): Some Severin models include a thermal fuse in series with the fan. Test continuity; replace if open with the correct temperature-rated fuse.
• Check wiring and connectors: Tighten any loose terminals and inspect for heat damage near the fan.
• Replace fan motor: If the motor is seized or open, remove mounting screws, note the orientation, and install a new Severin cooling fan motor. Ensure the blades do not touch any panels.
• Test: Reassemble, restore power, and run the oven. The cooling fan should start automatically when the oven heats and E7 should not reappear.
