Is there a reason you set freezer to -8*f? Since nothing happens when you push and hold the reset button, I’d check the I/m connection that is behind the little access panel left of I/m. Also, make sure you have that ice maker turned on at the user interface. I have not seen an I/R sensor on this style I/m.
From what you’ve described, I would do what i suggested, plus, I’d set freezer temp to the manufacturers suggested 0*f. Allow the box 24 hours to adjust to the changes. This ice maker doesn’t dump ice like the one in the freezer. This one has the gas tube loop in it. It takes it a while to defrost itself before ice maker will dump ice. Since you removed it, it would have filled with water. I’d check to see if it filled.
10*f is not 9*f. These I/m sensors can fail. You need an accurate thermometer.
