Real world,,,,,, replacing a 1/8th HP condenser fan motor with a 5HP condenser fan motor,,,, will be toast in a short period of time.
I have been watching this thread and believe that "all" has realized that there is more to a motor then amps and volts alone, there is the design of the motor with its power factors, break horse powers, service factors, etc, etc. That on occasion need to be considered when having issues on a newly installed/problematic system.
I also stated that on a newly installed/problematic system that sometimes the only thing that can truly help you diagnosis and repair the system is to know and understand the total design of the system. The "system" meaning all of it, the dampers, the coils, the duct work, etc.
My point, you need know more then amps and volts. A static reading and someone locating the specs on this unit, would have helped us to diagnosis this/ rule out design.
My problem with this thread and in the real world, is how often the design, the instructions, is ignored. I get several phone calls daily from techs stating that they have done this or that, replaced blah blah blah and now it does not work? when I ask if they have read the instructions and checked the other pieces to the puzzle, the answer is almost always no?
When I ask them to check "all" the pieces to the puzzle, read the instructions and to call me back "if" they have any more problems, I seldom get the return phone call, crazy eh?
