I just had a service man out to see about the load noise the condenser fan made when turning on. They looked and said it was a bad fan and replaced it. However, now the fan runs constantly. I can leave the refrigerator closed for 12 hours and the fan will still be running. I called sub-zero and they said the unit has 2 condensers. so the fan will run a lot. This seems abnormal because for the first 3 years of having the unit, I did not hear the fan noise all the time. Thanks, Kirk
