When my dad's BTFP01012 air compressor reaches 150 PSI, he uses the relief valve, and the unit stops working i.e. turns off and does not restart to replenish the air.

So he replaced the pressure switch. The symptom is now random. After reaching 150 PSI, he uses the relief valve, and the unit sometimes stops working i.e. turns off; otherwise, the unit continues working as usually, continually gathering air. When the machine stops working, it can't be turn on for awhile. What do you think seems to be the problem?

  • Is there a thermal overload protector somewhere on the compressor motor? Sep 17 '17 at 17:05
  • In fact, can you post a photo of the compressor motor's nameplate? Sep 17 '17 at 17:05
  • @ThreePhaseEel I have added a link to the picture of the nameplate. It is too big to put directly here.

  • Is there not a nameplate on the motor itself? Sep 17 '17 at 17:32
  • @ThreePhaseEel Not that I can see. The typography on the device itself is pretty bad; I did not know what was the model number for the longest time.
