Manufacturers make it difficult to repair things these days for a variety of reasons, a culture that must change as we move towards net zero.  My Q350 fan motor repair was no different.  It turns out that it was just two tiny bearings on the fan shaft which had failed and a local ‘Armature Winders’ R.W.Wilson replaced then for £150, avoiding scrapping the whole unit at £460 and the inevitable waste of materials and carbon.  It took quite a bit of effort, but it should have been a standard repair.  As a culture we have to design for longevity and easy repair.
