PROBLEM

CAUSE

CORRECTION

Motor will not
run.

Fuse blown, circuit breaker
tripped.

1.

Check fuse box for blown
fuse and replace as
necessary. Reset 

circuit

breaker. Do not use a fuse
or circuit breaker with
higher rating than that
specified for your
particular branch circuit.

2.

Check for proper fuse. You
should use a time delay
fuse.

3.

Check for low voltage
conditions and/or proper
extension cord.

4.

Disconnect the other
electrical appliances from
circuit or 

operate the

compressor on its own
branch circuit.

Motor overload protection
switch has tripped

Let motor cool off and
overload switch will
automatically reset.

Tank pressure exceeds
pressure switch “cut-in”
pressure.

Motor will start automatically
when tank pressure drops
below “cut-in” pressure of
pressure switch.

Loose electrical
connections.

Check wiring connection
inside pressure switch and
terminal box area.

Have checked by a Trained
Service Technician.

Check valve stuck open.

Contact a Trained Service
Technician.

Possible defective motor
or starting capacitor.

Have checked by a Trained
Service Technician.  Do not
operate the compressor in the
paint spray area.  See
flammable vapor warning.

Paint spray on internal
motor parts.

Bleed the line by pushing the
lever on the pressure switch to
the “off” position; if the valve
does not open, replace switch.

Pressure release valve on
pressure switch has not
unloaded head pressure.
