Awesome vid. recently ran in to these motors and didnt jump the dc output to the ai which i could of now seeing the video but instead used a 9 volt battery lol
I want to learn HVAC, but there are those who say the learning period is 6 months, and there are those who say 2 years, and there are those who say 4 years, which is true?
Those ECM condenser fan motors are junk. So many of them fail, and its not just one brand....its all of them. We service a site that has 2 RTAF'S. Each chiller has 14 fans and between the 2 chillers we have replaced 12 motors already, same with RTAC's. Had it happen with dry coolers, chillers, fan walls etc etc. Give me a conventional synchronous motor and a VFD
