sanborn/coleman 5 hp 27 gallon struggles when starting

Bill: My compressor motor struggles when starting and seems to run slow. It builds 120lb pressure but takes 4-5 min. I checked the motor wiring and it's correct for 120 volt. Have you any ideas why? Thank you

If no change in your wiring or power supply to the Sanborn air compressor, my first thought is that you need to check your run capacitor. In fact, check both the start and run capacitors.
