Perhaps I misunderstand but never heard of AC adjusting fan speed on its own.
Ours is as follows.
High constant
Low constant
Auto high
Auto low.

the time delay starts when the uni has been TURNED OFF. it will not try to cycle it's self in just 3 min. if you turn it off or the power goes out it will not restart for ten min. not 3.

When it "seeks" between high and low fan, it's the fan shutting down - not the compressor. If you listen, you should be able to hear that. It's irritating but shouldn't do any damage. When those conditions occurred in our previous rig, I would just put the fan on high full-time and let the compressor cycle on and off as needed. The Coleman Machs in our new rig are set up differently, though.

The high and low speeds are different windings in the fan motor and one needs to be off before the other is energized.
A hot day mine usually will jump to high and stay the rest of the day. After sundown it may cycle up and down a few times as OP indicates until it settles for low for the rest of the night. I have no concerns.
