It still seems to be working well and water is flowing to the drain ( crawl is dry and comfortable). but the buzzing/ pulsing noise is slowly getting worse. Do dehu components start to "complain" when under load and failing? I'm trying to figure out if I should package and ship the unit for repair now,based on the noise alone, or wait until the unit dies? I read a recent post here about a good service experience for the same unit ( santa fe) but I don't have any formal diagnosis or opinion fom an hvac person. Any thoughts?
Guessing that the sound you hear is the fan and compressor are going in and out of phase with each other. Ordinarily, this sound should not be noticed. Possible that components are touching the case amplifying the sound. Remove the shroud, try to locate scource of the vibration. Copper tube should be moved to eliminate the vibration. I am not aware of any damage that will occur by operating until a component fails. I would operate the unit for the rest of the season. Fan motors are shorter lifed than compressors. At the end of the season contact the service dept. at 800 533 7533 and tell them of your concerns.
