I have a worcester 350 boiler and occasionally the heating does not switch off when the timer is set and the fan continues to run after the burner switches off ( which is normal for a few seconds) but this just continues to run. as this is not a constant fault i suspect there is a sticky switch or relay has any one had experience of this or could point me in what direction to look??
