Status Light issues

So Iv been noticing my status light is not functioning properly. Not a huge deal but thought I’d post. When green the top to parts of the triangle are green and bottom is blue. When idle after cut believe it is all orange but again bottom is one color two upper portions are another. Iv had two random IHC or THC warnings come up within a couple weeks. I took cover off and cleaned out z axis so not sure if it was hanging up or if there is something else going on. But the lights are acting weird.
