Help! I'm in trouble - The Management's away and if I don't get the boiler fixed by her return on Friday I shall really be in the .. er, .. you know!
Old (guessing 15 years +) Potterton Kingfisher CF60 boiler was smelling a bit, so I thought it was due for a clean. Wasn't too worried about the smell, 'cos it's in a little closed room with its own air vent, but I haven't done anything to it for a couple of years, so decided to do a "service" ...
Took the front off the combustion chamber and found a big sooty lump - sort of cone-shaped, about 2" dia at the base x about 2 1/2" high - hanging down (pointy bit towards the floor) from the left hand end of the heat exchanger. I removed it and generally brushed and vacuumed everything clean, fitted a new thermocouple and re-assembled. Unfortunately, the burner flame is very yellow, and the fumes are worse than before.
I did kinda expect to have to replace the boiler before long, but with the cost of Christmas and a big bill from the car menders last week and (pout, whinge, self-pity etc.) I really can't afford to do so right now. Any instant fix??
