The dreaded buzzing problem Empty The dreaded buzzing problem

All
It appears a lot has been written on this subject. I think I have just replaced the timer delay PCB uneccessarily. I think the buzzing is comming from the pump drive PCB. Some have suggested that the basic problem relates to a failure of the on-board smoothing capacitors. What I do not understand is why should my buzzing occur for about 2 seconds about every couple of hours when I understand the sole purpose of the pump drive is to swith the CH pump on every 40 hours.

The Delay PCB
And the pump PCB are common faults.
I always recommend changing both at the same time.
More so if they are the same age.
And also they are located in a very hot place.
