hi all.
the boiler is a glowworm swiftflow 100,around 12 years old and regularly serviced.
when on demand for either heating or hot water the pump and fan will run.You can hear the click at the air pressure swich but thats about as far as it goes,the main burner wont light.A few weeks ago the fan was jammed and wouldnt start.while I was up there, I sucked on the white tube from the fan to the A.P.S to make sure the A.P.S was operating anyway and the boiler lit up fine.I am wondering now if the A.P.S is faulty or if there is a problem with the P.C.B! grateful for any advice,thanx in advance!
