Protools on EMR in San Juan.
The pressure switch should cutoff the compressor motor at 120 to 155 psi for that model. Check that the pressure gauge is reading high enough for cutoff.
Sometimes the actuation mechanism requires dusting and cleaning. Open it up, blow it out.
Add some WD40 to the actuator and let it sit for 20 minutes before testing.
If that fails, swap out the pressure switch for a new one. They should cost between $100 & $300.
