No voltage in the pressure switch
Motor winding failure, damaged
thermal protection
Capacitor failure
Seized piston or other rotating part
Pressure switch does not switch
Air leakage in pneumatic system
Non-return valve (SV) leakage
Large volume of condensed liquid in
pressure tank
Low compressor capacity
High air consumption of supplied
equipment
Leakage in pneumatic system
Solution
Check voltage in socket
Check circuit breaker switch –
switch to position switched-on „I"
Loose conductor from terminal -
repair
Check electrical cord – replace
defective cord
Replace motor or windings
Replace capacitor
Replace damaged components
Check function of pressure switch
Check pneumatic system – seal
loose connections
Clean non-return valve, replace
seals, replace non-return valve
