Grundig oven shows F5 and fan‑assisted modes do not heat correctly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed convection (circulation) fan motor, Open fan heating element, Obstructed fan blades, Faulty relay on control board

Safety first: Isolate from mains and allow the oven to cool before removing the rear inner panel.

Check fan operation: In a fan‑assisted mode, listen for the fan. If silent, the fan motor may be faulty.
Inspect for obstruction: Remove the rear inner panel (inside the oven) and check that nothing is jammed in the fan blades.
Test fan element: Use a multimeter to measure resistance of the circular fan element. Replace if open.

If both fan and element test good, the control board or wiring may be at fault and should be checked by a technician.
