CARRIER WITH PURON
MODEL : 38YXA036300

THE WHOLE MACHINE VIBRATES ... IT IS INSTALLED ON THE HOUSE WALL WITH 2 ALUMINUM TRIANGLES ... AND 2 SCREWS ARE HOLDING THE MACHINE ON THE STAND ... I DID EVERYTHING TO MAKE SURE THERE IS NO LOOSES PARTS OR PIECES ... THAT NOISE REALLY GETS TO YOU ... IT DOESN'T LOOK LIKE ITS COMING FROM INSIDE ... TRIED TO PUT RUBBER BETWEEN THE MACHINE BASE AND THE TRIANGLE = NO CHANGE ... WHAT CAN CAUSE THE VIBRATION ???

Often it is loose parts. However if you are sure that is not the case, it is either the compressor or fan. In my experience, a low vibration is often caused by an unbalanced fan. This could be a fan bearing problem or something else on the fan. Sometimes a technician can use a stroboscope to check how the fan is rotating.

Before going too far....be absolutely sure that nothing is impeding the fan operation.
