Purposely burning out the motor isn’t a good idea. Damage to harness wiring, possibly starting a fire, etc. Like you say the fuse-removal idea probably wouldn’t work. I think the first thing to do is remove the motor and see if there is any debris in that area which is interfering with the rotor blades. That’s not an unheard of complaint here. Might be something very simple in other words. Maybe oiling the bushings, etc.
If it is not simple, and you have the motor out, I suppose you could take the motor apart and disable the innards somehow. But that seems like a lot of work, and whatever you do might cause other unintended problems. Suggest to just replace it w/a new one.
