I saw reference to this a couple years ago and even though I didn't have an LG then, the concept stuck. I recently got an LG to use as a hatcher and now I know why so many complain about getting the temperature just right- that dinky stick knob is useless. Here's the fix- it's the cap from a 16 oz. juice bottle with a 7/32" hole drilled in it. That is a bit small so I carved a little more with my pocketknife, until it fit snugly. Credit to DH for the bottle cap, I was thinking of wood when he spotted the cap! It makes it much easier to adjust in tiny increments.
