Britannia CK2000 canopy hood start delay

[Eaglestef]

I have a fault on this CK2000 hood; on selecting a fan speed, instead of the fan starting up immediately, there is a 5 – 10 minute delay and finally the fan will start and then work as normal.
Any ideas which is the faulty component here?

can you hear the fan motor trying to start ?

look at the fan and see if its moving even very slowly

Hi, thanks for the reply. Neither of the fans move at all, on speed settings 1,2,3 or 4. The only thing that you can hear is a very quiet electrical buzz when fan is activated at the switch, but it is very faint. When it finally starts working minutes later, the fans turn as normal.

when you hear the buzz try giving the fan a push and see if it tries to go

Thanks Dave, I’ll try that this evening!

which means in my opinion your probably looking at a board problem as the motor is not energised for 8 minutes. if the motor had tried to start it may have been a capacitor

Thanks Dave, I have searched on line for a PCB, the only thing I can find, is on the ukwhitegoods site, and is the ‘Cooker hood switch module’ , described as the switch unit and PCB assembly. Does this sound like the part that I need?

if its this one then I dont think thats the main pcb. it looks like a control board only. there must be another power board in there somewhere

Thanks Dave, that’s a shame, I can’t find a main pcb for sale anywhere for this model. Do you have any recommendations of where else to try? Stefan

think the first thing to do is find it and see if any components look odd

look for capacitors with bulging tops

OK Dave, thanks for the tip. I’ll try that at the weekend.
