Testing CFM of Refrig Condenser fan. Is my motor slow?
Other than putting you hand in front of the fan, is there a reliable way to test the cfm output of a refrig condenser fan, or know what it should be?
I've seen a digital cfm tester at Lowes.
After cleaning the condenser coil, I still think I am not getting enough air through that coil.
It's on a SubSero 700, but the question really applies across the board to all refrigeration.
I know all ac motors are supposed to run at their synchronous speed, but I've heard of fan motors needing replacement from running slow.
Have others encountered a slow condenser or evaporator fan motor?
