What to do if my SpeedComfort Fan doesn't switch on?
- LLisa StevensAug 15, 2025
If your SpeedComfort (A) fan doesn't switch on after connecting it to the wall socket, ensure the radiator's temperature is at least 33°C. Check that the temperature sensor (E) is correctly attached to the warm water supply pipe or nearby on the radiator where it gets warm and makes proper contact. If the radiator isn't heating up well, bleed the central heating system and consider hydronic balancing. Also, verify the wall socket is functional and the power adapter (D) is properly inserted.
