    Santa fe advance noises -Early warning ?

    My Santa Fe Advance has been working beautifully for @ 4 years in my crawllspace This summer it started making a "wup-wup-wup-wup" kind of pulsing / buzzing / vibration noise ( sorry for the cheezy description). I don't hear it with fan only turned on but when unit is dehumidifying we can hear it all over the house. 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.

    Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"

    Thanks teddy bear. I appreciate you taking the time to reply. Hate to see any issues with this unit, I have to say it's done an amazing job so far.
