Noise from air conditioning

Over the last few weekends I've been getting this noise from the ac. Does not happen with blower only running, happens only when compressor is on heat or cool. If you listen closely you can hear it's like an insect buzz in the background. Any ideas? Link to see/hear below

    You may need to put rubber shims between the pan and the hull to dampen the noise. There is also a damper blade inside that large air grill that may cause the noise.

    Thanks guys - I'll play around this weekend. Is the damper blade inside the large grill on the unit itself? Like near the coils?

    Controls the air flow to the bathroom

    I just stuck a screw drive though the slot and touch the damper and the sound stopped. But I never fixed it but know what the sound is.

    My dampener was ok, PO had stuck a wine corn between the baffle and the wall to get good air flow to the head and to stop vibration. I opened up the compartment with the compressor and there was a plastic wire holder touching the compressor, moved it away and no more noise. All good.

    It might be due to faults in compressor, lose connection or malfunctioning. Check the connection and compressor is their any leak or fan problem and clean it.

    That compressor buzz you get is what keeps us awake at night, wish that could be dampened somehow. I'll look to see if I can put something under. But I also don't have any dampers or blades, just the R/A grill

    Regards,

    I used some rubber pads double on opposite end of drain to keep the pitch

    Like I posted back in October this was just wires pressed against the compressor, once moved away no more noise. When we had the 2001 310 the ac would indeed wake me up when it kicked on. Not sure what they changed but it does not wake me up on the 342.

    Well my new one is super quiet. Since its water cooled you could experiment by putting that blue panel insulation or something else around it
