I know you have checked voltage. However please remove the fuses for control power and check,also check fu4 and 5 16volt fuses. next check power on the controller input. Don't remember terminal # but if you look in electrical cover removed to gain access, a wiring schematic will be affixed to it. I think it's on j5 terminal 36 110volts. But please check the schematic first. If you have power at the input terminal I suspect the controller is bad but continue with the following checks. If no power at terminal 36 check the hat (High Air Temperature) switch. Its located on the end of the airend and about 1/2 inch flex connected.If the hat switch is good check the emergency stop contacts. Note the power lite picks up voltage before the emergency stop and hat switch. So even though the lite is on one of these switches may be bad.

SOURCE: What does alarm start fault
I use to start up a 25 HP Ingersol screw type compressor. The only alarms I got were from power spikes which just needed the reset button to be pushed, then the on button - and the low oil sensor would shut it down and give an alarm when the tank was about half way down. They will blow up with no oil so there is a saftey margin on oil level.

Start with the simple things first... had a fellow a couple of montha ago that did not realize that there is an air filter....cleaned that and the air compressor worked great a again....
So... check your air filter...
Also does that model have oil in the crankcase??? is so check that you are part way up in the site glass with oil...if the unit has been used heavily, has the oil every been drained and changed???
This could contribute to rings getting sticky and hanging up...
If none of these things work then start going deeper into things...
