New H/F compressor model 67847 wont stop running

New H/F compressor(67847)wont stop running, Gets to about 90psi, stays running
I got a HF air compressor the other day, the 67847 model, 2.5 HP, 21 gal, 125 psi.
Its the upright black oil black one.
Well, I get it home, ran it with compressor oil for 30 mins, drained, replaced oil, started using it. Worked great. Would kick on when it got too low and shut off when it got to the desired psi. I probably used it an hour or so by day 3.
The 3rd day during use it had drained below the psi that makes it kick on by itself, tried to fill itself back up, but it never stopped running. The pressure gets to about 90 on both of the gauges. 91 or 92 maybe at the most.
But it just runs and runs without ever shutting off by itself like it did at first.
Again, its only like 3 days old.
I wonder if the pressure switch is bad or I also read there was a pressure something internally that I'm not supposed to ever shange or mess with. Thats fine with me. I just dont know enough about an air compressor yet to know what to do 1st, 2nd, 3rd and so on.
Troubleshooting would be fine with me if I knew where to start. Anybody know anything that I should do or have any ideas for help? Thanks!!
Marc, see the troubleshooting section on the sitemap page for a link to a page about why air compressors run and run but don't build pressure.
However, I would suspect a valve or gasket failure, and at 3 days old, if it were mine, I'd take it back and ask for a new one.
