Feeling the Heat
There a quite a few threads on this forum that deal with this problem, you may want to do a quick search.
You'll find people who have used penetrating oil, people who have drilled them out, people who have used high heat to break the corrosion.
Here's a recent one here:

Hello
I usually remove the 3 bolts holding the blower onto the stove and then get in on the back side with a long metal blade with my sawzall and cut the shaft. If you have a hacksaw you can do it by hand just not as fast.
Also Using a die Grinder on the impeller hub can save the motor shaft.

I used the sawzall, it took about 3 seconds to cut the shaft. This was the best way to remove the motor and fan blade, I'm replacing it all anyway. I'm awaiting the new Exhaust motor with fan blade and a new distribution blower. Stove has been used for ten seasons and I've decided to change the motors. I changed the feed motor a few months ago. I'll be starting all new next season for another 10.

Ahhhh...the 'brute force' method, leaving no survivors.
If you're concerned about getting the blade off anytime in the future you'll want to use some anti-seize compound on the replacement.
Amazon product ASIN B000LDDOXG
Amazon product ASIN B0006Q7H2M
Either of those should work.
Good work.
One more item I highly recommend!
I changed all the motors in my Harman Advance and then a few days later my auger jammed right up
No foreign objects and I was burning very good pellets. So I pulled the auger and 3/4 of it was black with pitch and the rest was dirty, stick and rusty! So I buffed it out with my wire wheel on my drill driver and sprayed it down with "Dry Moly" then I put it back it and it is working like brand new!PS - Make sure the auger bearing turns freely or you may need a new auger.
