Somebody else asked me about this issue today. This is what I wrote: "This morning I found a dealer who carries Blauberg parts. They calculated the faulty fan might cost about $250-300 plus shipping from Alberta to here, BC. The dealer is Master Group/Soper's Vancouver. 604-566-9370
BTW, I am assuming the part is faulty as it is seems the motor is wearing out based on my auto mechanic background. I am no HVAC expert. It is hard to find technicians and when you do, they charge a lot, plus the supply chain is still not back to what it was before the pandemic.
Anyways, provided I find the part, I am not sure if I could replace the part myself as I believe this fan is computer-controlled. I have contacted a few HVAC experts and they haven't called me back.
