Why Intermittent Probe Failure Should Be Split Between Connector Wear and Interface Service Risk
A probe that behaves intermittently often needs a cleaner split between connector-side wear and interface-side service risk before parts are chosen.

An intermittent probe problem sounds simple until the team starts buying parts. The real cost usually comes from failing to separate connector-side wear from a broader interface service issue early enough.
What this failure pattern usually looks like
The probe may connect, drop, recover, and then fail again under slightly different handling. That pattern often invites vague language like unstable, sensitive, or temperamental instead of a real failure split.
Why the visible symptom can mislead engineers
Intermittent behavior tempts teams to treat all connector-path problems as interchangeable. They are not. A service decision changes depending on whether the failure follows seating, cable handling, or the interface path behind the connection.
What to inspect first
Check whether reseating changes behavior, whether movement at the interface reproduces the problem, and whether the instability follows one connector path more than another. That tells you whether you are narrowing a wear issue or a deeper service path.
Why earlier correction matters
If the path is not narrowed early, teams replace what is easiest instead of what is right. That adds cost and slows the real repair.
