Asko Range F5 Error: Oven convection fan fault
Asko range F5 error is a common issue reported by Asko appliance owners. What Does Asko Range Error Code F5 Mean? F5 means the convection fan motor in the oven section has stopped or dropped below its minimum speed threshold. Asko ranges use a rear-mounted fan with a dedicated heating element for fan-forced cooking; when […]

Answer to continue safely
Is it safe to keep using?
Maybe. Conventional bake, broil, and the induction cooktop surface all remain functional. Fan-forced modes must not be used while F5 is active as the motor may overheat.
Can I reset the code?
Yes. A breaker reset clears the F5 display. The code will return immediately when a fan-forced mode is selected if the motor fault has not been fixed.
When to stop immediately?
Stop if you notice: Stop all oven use immediately if a burning electrical smell is detected during any cooking mode., Do not attempt to run fan-forced modes repeatedly hoping to free a seized motor — this risks burning out the windings..
Symptoms You May Notice
No airflow noise from the oven back wall
When a fan-forced programme is running the back of the oven cavity is silent — the fan that normally produces a steady hum is not turning.
F5 displayed when fan-forced mode is selected
Selecting fan bake or fan roast causes the oven display to immediately show F5 and the programme to abort without heating.
Food cooking unevenly across oven trays
If the fan is intermittently slow rather than stopped, items on upper and lower racks cook at very different rates due to poor heat circulation.
Burning electrical smell from oven back area
A seized fan motor drawing excess current overheats its windings and produces a faint electrical smell from the rear of the oven cavity during use.
Possible Causes
Seized fan motor bearings
Years of high-temperature operation degrade the fan motor bearings until the shaft seizes, triggering the under-speed detection that logs F5.
DIY PossibleFan blade obstruction
An oven rack, tray, or dropped utensil contacting the fan blade cover prevents the blades from turning and stalls the motor.
DIY PossibleSupply relay or wiring fault
If the fan motor spins freely by hand but will not run when powered, the relay on the control board or the motor supply wiring has failed.
Requires ProfessionalSafe Checks You Can Do
-
1
Check for physical obstruction
With power off and the oven fully cool, remove all oven racks and look at the circular fan cover at the centre of the oven back wall. Check for any object lodged against it. Try to spin the visible fan blades through the cover holes — they should turn freely with light resistance.
If the blade is stiff or completely locked when turned by hand, the motor bearings have seized and a motor replacement is needed.

Test conventional bake modes
Select conventional (non-fan) bake at 180 °C and verify the oven heats to temperature normally. If conventional modes work, the oven is partially functional — you can continue using it with adjusted timings until repair.
When cooking with conventional modes instead of fan-forced, increase temperature by 10–20 °C and add 10–15 minutes to cooking time as a starting point.

Inspect fan motor connector
With power fully off, the fan motor connector is accessible by removing the fan cover (typically two screws inside the oven cavity). Carefully disconnect and re-seat the connector, checking for heat damage or corrosion on the pins before reconnecting.
Photograph the connector before removal to ensure correct polarity on reassembly.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Fan blade is free to spin manually but the motor will not run when powered — relay or wiring fault.
- Motor shows signs of winding damage (discolouration, burning smell) from repeated attempts on a seized motor.
- F5 persists after motor replacement — possible control board relay fault.
