Hi,
I have a Worcester Heatslave 15/19 Combi Oil fired boiler. When either the central heating or hot water is triggered, the pump kicks in, then when the burner starts a noise starts which sounds a bit 'worn bearing'-like. Removing the burner box cover on the boiler makes the sound louder, further suggesting the problem is more burner oriented than pump oriented (the pump is outside the burner box). This sound started a couple of days ago, and has been intermittent, but is getting more regular.
From searching the forum, it sounds as though this is possibly the fan. Here come the questions:
1. Assuming it is the fan/fan bearing, is this a seperately available part?
2. Assuming it is, should I be able to replace it? I'm reasonably competent (replaced diverter valve and flow switch - can do basic plumbing - got an OND electro/mechanical engineering). My main concern is that I'm removing and replacing the burner. Is this likely to upset any settings that would need re-calibration (such as oil pressure and air adjustment)?
3. If it's not likely to be the fan, any ideas on what it may be?
I would call in my heat engineer, but cannot remember his name or phone number, and have been stung by other incompetant ones.
Thanks for your help, and if I can give any more info, please let me know.
Thanks,
Crispin
