Rad fan bought last year and only used for a few weeks is not working and the green light on the plug is flashing anyone have the same problem

Mine too all of a sudden, did you work out cause?

I have low surface temperature radiators, will the heat sensor still activate the fans or can it be bypassed

So long as the surface temperature reaches a minimum of 40˚C then the fans will activate.

Which of the fans are more effective in heating up the room? The ones that clip on the top or the bottom of the radiator?

Hi, not sure about the ones that clip on top as our radiator is in a cabinet and the one that goes on top wouldn't have fitted. I can say that i originally got the slim small and didn't notice much of a difference so sent it back and got the medium with the 4 fans which made a noticeable difference and the room heats up quicker now.

i tried attaching it to the radiator, but its not magnetic so wont attach? what am i missing?

The fan is a sort of L Shape with a lip that comes up the front of the radiator. The magnets are in that lip and that should sit on the front of the radiator.
