[Error Code] 6501 c-0322

[Guest]

6501 is throwing (M67) fan abnormality detection signal code c-0322.
Is there a quick way to either bandaid the issue or to determine which of these two to replace?

"Conveyance drive board (CDB)
ADU fan /2 (M67)"


any assistance would be appreciated

First at all, you should check the adu fan itself, maybe it is blocked by paper debris or something. Then do an I/O check; the check code is 42, the multi code is 20 for m67. Third, remove the left adu cover and attach a meter to the wires of the fan, it needs 24v, are they there when fan is activated?
