BGas say our 5amp fuse feed has damaged boiler.

I don't think I've known a higher fuse rating wipe out a PCB. I would maybe engage with a local engineer or even perhaps a fixed price repair from Ideal, could be the BG engineer couldn't be bothered to fix, could be cop out or maybe just the hard sell of a new boiler. I've just looked at PCB prices and they vary in cost. Get rid of BG too.

Yes that's about right, don't know why their service man last year didn't know the 3A / 5A potential problem. Their excuse seems to be that our kitchen fitters had boxed it in restricting access. The Boiler is a combi Ideal approx 12 years old, not home so can't give model No.

If it is 12 years old it might be a Logic. I've just been looking at the manual for the Logic It mentions an internal fuse. I have no idea what it does or whether it should have prevented any damage from a short etc.

I've not got boiler cover myself but if they're willing to take your money for insuring it surely it's up to them to front the cost of a replacement if that's what's required?

Assuming the boiler is connected to a FCU you could try replacing the FCU fuse, unplug or disconnect the power cable at the the boiler (safety the exposed wires if you do the latter), then switch on the FCU and see if the fuse blows.

first part of bg service visit is electrical safety check part of which is to check it has 3 amp fuse fitted so just tell them its them that checked it and left the 5 amp fuse in . if you have a service contract regardless of how dear the parts are if they are still available then they should be fitting them under the contract ask to speak to lead engineer/patch manager dont be fobbed off

It's utter nonsense; perhaps they're asserting that the boiler happily normally runs, drawing less than 3A then "oh no" something has gone wrong in the boiler and it suddenly started drawing e.g 4A! Normally that would blow the 3A fuse (probably not, actually) and this external protection would stop the boiler damaging itself! (But because you fitted a 5, that let the boiler blow itself up with 4A)

What cobblers.

No manufacturer would make a device that is totally reliant on factors outside their control to prevent damage, not when they can take control by fitting protection inside the device (which they have, according to MNW67; a 4A internal fuse)

Unfortunately I suspect you'll find a succession of doylems right the way up the line as you argue this
