Recently had to have my dead boiler repaired. and was set to have the main PCB replaced with a (self-sourced) reconditioned one rather than a brand new one at an eye-watering price.
In the end the problem turned out to be something else; however my point in posting is that the engineer tried to warn me off using the reconditioned part because he says that he's heard of somebody having had a house fire caused by one, followed by the resulting insurance claim being turned down due to the boiler not having been properly repaired by a standard manufacturer-supplied part.
A fire is plausible I suppose, but as to the last bit I smell bullshit. Could it be any way legit for an insurer to reject a claim on the above basis (unless presumably they had highly specific and restrictive small print in their policy wording?)
