Only makes noise in A/C mode ??
Does that mean it's ok when just the blower is running ?

Yes, ok in blower only mode. Makes high whining noise in AC mode, one I associate with something caught around a fan rotor or similar. No instructions in manual for internal maintenance or cleaning - do I have to remove back panel to clear it? Sometimes just cycling the machine on and off will clear the noise but this time, no. Any help very appreciated! thx, scott

A high whining noise in the A/C mode sounds like a compressor problem.
The same blower runs in blower only or cooling mode.
