Do not guess. Look.
The machine and the last change beat a story about the machine.
How I use it
When something is wrong, I look at the unit, the last change, and what actually moved. I do not diagnose from memory. Speculation is expensive. Checking is cheap. I do not claim a thing is fixed until I have seen the live behavior.
What I refuse
I think it is the sensor. It is usually the sensor. It should be fine now.
