Help! K1 Max says Error Key 109 Fan Feedback Exception

The printer nozzle heats fine. The Extrude function works fine. The fans seem to be operating fine when I turn them on and off with the Settings control sliders.

But I can’t print anything because it says Error Key 109 Fan Feedback Exception.

When I look for a solution I find the Creality site that says the throat fan might need to be replaced, or the nozzle board might need to be replaced. I DO NOT KNOW what either of those things are.

Please help. This printer is only four months old.
