My ferolli boiler, has been making a loud noise, the fan, when the heatings on. Now I have turnt on, and the fans not turning on, and going round, so its not fireing up.
Please how can I fix it ???
Sounds silly but it needs a new fan. Fan not running, air pressure switch not detecting the fan removing products of combustion so it won't allow gas or ignition.
Hope this helps?
