Looking for a little help with my Harman 52i-TC insert.

I've had the stove a little over 3 years now and have never had an issue. All of a sudden, the stove is taking hours (3+) to shut down. It will shut off with some fuel in the hopper (doesn't need to completely deplete the fuel) but it is burning for hours on end even after I hit shut down. I can hear the stove feeding pellets for a long time after I've shut it off.

I did a total clean, cleaned the ESP probe, nothing works. Even with the stove in shutdown mode, the flame goes back and forth from small to intense/large.

Aside from the long shutdown time, the stove is working fine.

Any ideas?
