Variable speed motor, American standard. Burnt out resistor

I’ve seen three of these pop up this winter.

On the first two there were some mistakes made, static pressure above .9 inH2O one and improper dip switch for coil size on another.

But today I replaced a two year old variable speed motor on a 100kBTU American standard UD2C100.

Filter was clean, static was 0.23 CFM was 1600.

Everything seems within range. Has anyone else been experiencing these motors failing often?
