(P1 low display)
First, check starter wiring. If discharge
pressure is above 10 psig (0.7 bar) was
evident, then sensor is at fault—check
connections from transducer. If adequate,
replace transducer.
Compressor will not build up full
discharge pressure
Air demand is too great Check service lines for leaks or open valves.
