What Cooling Fan Runs Constantly means on your Asko cooktop (asko cooktop fan running constantly)
This is a symptom guide rather than the decode of a display code, since fan behavior raises no dedicated code on either the F-series or the E/Er-series generator. A cooling fan continuing to run for a while after the hob is switched off is normal — it is dissipating residual heat from the generator, the same way the fan behind the F7 and E2 overheat problems is meant to work as designed. A fan that never stops, even hours after the last use, or that runs constantly during light cooking, suggests the generator is working harder than it should to stay cool, which is worth investigating before it escalates into one of the documented overheat problems.
Symptoms
The indicators below help confirm the problem on your Asko cooktop instead of a different issue that mimics it. Your cooktop might produce one symptom or a handful at once, whether they develop slowly or appear all at once after a power event, a demanding wash or cook, or recent installation.
- The fan continues running well beyond the typical cool-down period after the hob is switched off.
- The fan runs at high speed even during light, low-power cooking.
- The fan noise is louder or rougher-sounding than it used to be.
- No error code appears on the display despite the fan’s constant operation.
Common causes
Any one of the causes below can be behind what your Asko cooktop is doing, which is why they are ranked by likelihood. Checking them in that order helps you judge whether your cooktop needs a homeowner check or an experienced technician with genuine Asko components.
- Normal extended cool-down after heavy, high-power cooking — a fan running for a while after use is expected behavior, not a problem.
- Restricted airflow around the hob’s underside — a blocked vent forces the fan to work harder and longer to achieve the same cooling.
- A generator running warmer than normal due to a developing problem — the same underlying pattern behind the F7 and E2 overheat codes, showing up as fan behavior before a code appears.
- A worn fan bearing causing it to run at an inconsistent or elevated speed — a mechanical issue with the fan itself rather than the heat load.
Troubleshooting steps you can try
Work these checks on your Asko cooktop in the given order first — you may not need a technician at all. Stop wherever you are unsure on the cooktop, or where live electricity, gas, heat, water, or a sealed part is involved, and let a qualified professional carry on.
- Time how long the fan runs after switching the hob off and compare it against a typical light-use session.
- Check the ventilation clearance under the hob for any blockage from cabinetry or stored items.
- Note whether the fan runs constantly even during light, low-power cooking rather than only after heavy use.
- Listen for any change in the fan’s sound, such as a new roughness or inconsistent speed.
- Book a technician if the fan runs constantly during light cooking, stays on for hours with no heavy use beforehand, or sounds mechanically worn.
Parts a technician may replace
When your Asko cooktop shows this problem, a technician will inspect, test, or replace the cooling fan, induction generator, and ventilation clearance as needed. The part is pinned down from your cooktop’s model, serial, and Art. No., and only genuine or trusted-supplier parts go into the cooktop, so the repair lasts.
When to call a technician
A technician measures generator temperature at idle and under light load to determine whether constant fan operation reflects a genuine heat problem or a fan-bearing issue alone.
