I finally got around to taking apart my air compressor.
Kobalt 60 gallon oil bath compressor. 230v
It has a problem where it will run and slow down at about 65 psi, then stop at 90 and trip the breaker. It will not run past 90 psi, even after sitting over night. In a previous thread, it was suggested to replace the capacitors. I replaced the run and start capacitors and it exhibits the same issue.
I took apart head off tongight and i can't see a problem, the valve block seems simple enough, although you can't tell what the valves do hot. I suspect perhaps its the electric motor. ITs $289 or so, the valve block is $70.
I'm hesitant to spend $200 on an 8 year old $450 air compressor. Should i just cut and run for a newer , better compressor?
