Had a well noisy boiler for past 24hrs, so started to strip panels off and investigate. Noise was coming from fan. Well i need a service so i contacted my friendly corgi shop and booked for next Wednesday. Whilst i was on the phone i asked the lady to ask the fitters if it was ok to run the boiler with fan as i had a 3mth old grandasugher in house - she phoned me back later to say yes. Well tonight im now without heating/water - sods law. Can a fan go totally which would cause the boiler now to not ignite or run? If so im thinking of doing a collect and changing it myself. Why do boilers go at the most inconvenient time
