Im having trouble with this boiler as in that when calling for heat and hot water the fan and pump work ok but no spark at the burner then the boiler trips out.
Looking at the pcb i see burn marks on it and assume it is knacked as this is a common fault on these boilers.
if i wanted to test the air flow switch how do i do this, could some one tell me in detail how to carry out this test.
thanks in advance.
