I/R T-30 5hp single phase (10+ years old) bad caps
by Pete White
Have diagnose bad capacitors but am wondering if I should go ahead an replace the entire motor with a new one instead of replacing just the capacitors. Thanks PKW
Good question, Pete. The only way you could tell for sure is to take the motor to an electric motor rebuild shop and have them do a test on it.
Even then, being as old as it is, it might fail right after they say that it's fine... could happen.
How critical is the compressor to your operation, and what will it cost you to have unexpected down time? If that's a lot, then preventive medication like changing out the motor too might be a cost saving in the long term.
