quickly check that the o heat stat under boiler hasnt tripped first
iv ghecked that was not tripped out
you could link it out but you can also check switch electrically without power on using multimeter. Check if you are getting continuity between common and normally open when you make switch by sucking and pinching
ok thanks i will test the aps if its working ok what else could it be
you can check for 240v on the pcb t4 orange from the aps and t2 is the black from the gas valve.
if yes pcb fault if no aps fault.
if yes pcb fault if no aps fault.
hi its running constantly
just running constantly
boiler fixed now new fan fitted thanks for your help
its funny you say that it worked all day now its doing the same thing again. Think the old fan was runing a bit slow as it fired when i sucked on the pipes on the aps. S0 i will fit a new aps next see if that works it also fires up if i pull the clear hose off the aps any ideas.
