MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
Step 3.
Check air system pressure.
Compressor will not start if pressure is between 1500 and 1800 psig (10342 and 12410 kPa).
Step 4.
Switch to manual valve operation. Refer to para. 2-34.
Step 5.
Notify unit maintenance.
4. Noisy or burning smell from compressor belts.
Step 1.
Notify unit maintenance.
5. Air pressure cycles rapidly between 1500 and 1800 psig (10342 and 12410 kPa).
Step 1.
Check air reservoir tank block valve.
Open valve.
Step 2.
Notify unit maintenance.
6. Air compressor runs continually but does not reach 1700 to 1800 psig (11721 to 12410 kPa).
Step 1.
Close high pressure auto blow down block valve.
Open valve for 30 seconds every 15 minutes if compressor now runs correctly. Notify unit
maintenance.
Step 2.
Check inlet air filter.
Change if dirty or plugged.
Step 3.
Notify unit maintenance.
7. AIR COMPRESSOR circuit breaker opens whenever air compressor is started.
Step 1.
Notify unit maintenance.
8. Air compressor overloads trip open repeatedly.
Step 1.
Notify unit maintenance.
9. Air compressor/motor is noisy.
Step 1.
Notify unit maintenance.
10. Air compressor assembly leaks air.
Step 1.
Notify unit maintenance.
11. Air compressor does not start.
Step 1.
Check COMPRESSOR ON/OFF switch.
Turn on.
Step 2.
Check air compressor circuit breaker.
Switch on.
Step 3.
Check air compressor starter reset button.
Push in.
Step 4.
Check air system pressure.
Compressor will not star if pressure is between 1500-1800 psig (10342-12410 kPa).
Step 5.
Switch to manual valve operation.
Refer to para. 2-34.
Step 6.
Notify unit maintenance.
12. Air compressor runs but does not build up any pressure.
Step 1.
Check for open air drain valve.
Close any open valves.
Step 2.
Check vent valve on top of air filter chamber.
Close if open.
Step 3.
Check high pressure auto air blowdown.
Close block valve. If compressor builds up pressure, open block valve for 30 seconds, every 15 minutes
during operation. Notify unit maintenance.
