Thermador T36IT71FN/01 stopped making ice; changed filter, still no ice

[Luminary Crush]

The ice maker had been working normally for a long time but recently stopped making ice. I changed the filter, even though the "FILTER" change notice wasn't displayed it seemed like it had been a while. Still no ice. I reset the unit to factory defaults per the manual, still no ice.
Randomly I was near it when I heard an unfamiliar buzzing noise which sounded like an electric motor trying to turn but failing. This sort of reminded me of the noise the ice maker makes when it's dropping ice into the holding basket but as if it was under duress. So, I feel it may be 'jammed'.

What could be done to troubleshoot this further? Could a cube be jammed somehow to prevent the ice maker from rotating and dropped ice? I thought of taking a heat gun and trying to thaw the unit out while it's still installed (take out the top freezer tray and hold the gun on it for awhile...basically a high-temp hair dryer), or, perhaps better to remove it and thaw it out of the unit to see if it's just stuck/frozen (maybe something would be obvious upon inspection). However, I can't find any service manuals anywhere online for it so I'm hesitant to just start taking the torx screws out...
