As long as the small PCB is $40 it's fine. I had a central vacuum fail like that a couple of years ago, and the small PCB would have cost $350.
The PCB had already been replaced twice during the warranty period. Googled the major components and they were $3 - $5 a piece, just a couple of half bridge rectifiers, resistors and diodes.
Didn't want to risk a fire from a DIY job, which would have definitely voided my insurance, so I spent $400 on a new central vacuum unit (from a different brand).
Not a lawyer but I don't think home repairs void most home insurances in common law countries unless you are working with parts that are particularly dangerous, part of a safety system to protect others, and/or absolutely require a skilled professional.
I'm pretty sure that if a fire starts in my central vacuum unit, and my insurance company does an investigation that finds a DIY swap of power electronics components in that unit, I would at the very least be in a lengthy legal battle to get any money back.
That’s not true in the US, which is what the post above yours was trying to explain.
