Agree with all. Sometimes, a mechanical problem causes the shaft to "bump" the rotor part just enough to cause a problem. A tiny drop of WD40 allowed to soak into the junction of the shaft with the body and a few dozen gentle back and forth min to max twists can help rule this out. I have not killed a control yet with Deoxit 5, but there's always a first time.
