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?
