Success...its off. Did a search of the website which I should have done first! Usually the problem starts with the set screw but mine came right out. The fan was frozen on the shaft so sprayed some WD-40, tapped it with a big screw driver and off she came. Only two seasons of burn but she was nasty underneath. Blower fans behind unit were fine, just vacuumed, put some duct tape over the chimney inlet and closed it up. Put duck tape on my cord plug as a reminder. Wire brushed all the removable panels, will spray with PAM and add some Damp Rid.
Good work!
You were lucky my set screw stripped.
Here are pics of what I did.

I spray my blades and shaft with "Dry Moly" and remove it once a year, then after cleaning behind the blades, I spray that area with dry moly also.
If you want to get fancy, you can also clean the area behind the blades with Acetone and wire wheel any rust off, then spray with high temp stove bright Satin Black stove paint or Ultra High Temp Flame Proof Flat Black 2,000 Deg spray paint from the auto store used for headers.
WD-40 works and sometimes PB Blaster works a little better.

Great - thanks! Actually, the thread you post is one of the threads I read - thanks again!
Why not Scott? As many Harman owners know when it comes time to take that fan off to replace the combustion motor, it can be a bear of a job with the end result having to use a cutoff wheel and cut the shaft. It would seem prudent to remove it every couple of years so it will come off when you want it to....
X2 Why not?
I take mine off every year so it will not get frozen. Also it is much easier to clean behind there with the blade off. Then I can easily upgrade to the new double paddle blade that has each petal riveted.
Sorry' don't know the size as I used from a set. I will tell you, it was not metric and the screw was exactly the one size (not this one or another). It was also easier to take the wrench off the ring to use.
mine is 1/8", 2010 pc 45, should be the same but not guarantees.
And i pull my fan 2-3 times a year, reinstall includes a dab of antiseize on both the screw and shaft. No problems with fan sliding right off but it might be the frequency rather than the antiseize.
Going to add as far as fan removal, the fan itself wasn't in too bad a shape (only 2 burn seasons). But I was using the stove about 2 weeks ago, power grid shutoff and I was left with a sooty diesel like goo mess. Now thinking that although I have experienced outages (never had this mess) before during cold winter, the difference in temp created natural draft. Two weeks ago, it was in the low 60's, cold in the house, but inside/outside temp wasn't sufficient for natural draft. I really had a mess. I hit the entire inside stove with Simple Green ( not to be confused with Green Supreme ((which sux)) and I went through 4 undershirt rags that were completly black when done.
Gotta have those upgrades.X2 Why not?

When ya pick up a stove like this it needs a few upgrades
Golden-fire brown with tarnished gold trim

X2 on the anti-seize compound. Great stuff for many things where regular grease can't be used (high heat).
I had the same issue on the used Accentra II that I bought a few years ago. I had to use heat on both the set screw and the shaft to get the impeller off when the motor finally failed and had to be replaced.
Congrats on your fix!
