Running a job today (about after an hour of other jobs) and the air intake fan (right side of the machine) started sounding like the fan blades were striking the case. I reached under and pressed against the honeycomb holes, and it seemed to stop the contact & noise (and this was during a job, so it was still running).
The last month or so it’s sometimes made a strange sound now & then, but this was the first time sounded like the blades were actually striking either the case or the fan’s own squirrel cage. So I’m worried that the bearing is failing, or perhaps a screw or pin holding it in position has loosened/slipped, and it can now shift within the case?
So before it fails completely, want to find out if I can replace the fan myself, or if this requires the unit to go back for repair by the GF team? Your advice is appreciated!
