TROUBLESHOOTING GUIDE FOR NEW INSTALLATIONS
Symptom
Unit fails to start - Motor makes
no noise
Unit fails to start - Motor hums
Reset trips on starter
Unit starts but does not get to
full speed
Unit does not make any or very
little air
Possible Cause(s)
1. Insufficient power to compressor
2. Unit wired incorrectly
3. Wrong voltage supplied to unit
4. Loose electrical connections
5. Wrong size wiring
6. Blown fuse and / or tripped
breaker
7. Starter overload tripped
1. Unit wired incorrectly
2. Wrong voltage
3. Loose electrical connections
1. Unit wired incorrectly
2. Wrong voltage
3. Wrong size wiring
1. Insufficient power to compressor
2. Loose electrical connections
1. Drain valve open
2. Air leak
3. Restricted or blocked intake
Corrective Action
1. Source electric to the compressor is either the incorrect
voltage, insufficient wire size to carry the load, the fuse box or
breaker box is not sufficient to carry the load requirements to
the compressor
2. Any wiring other than what is stated in the manual could cause
a malfunction (see Wiring Section)
3. Make sure voltage is correct with the motor wiring (see Wiring
Section)
4. The entire electrical system should be checked by a certified
electrician. The incoming wires and the compressor electrical
connections should be checked. Loose connections will cause
malfunctions
5. Check that wire size is rated for the current of the compressor.
State and local codes vary widely and need to be checked
before installation
6. The breaker and fuses required for this unit must be time
delay.
A tripped breaker or blown fuse may result from a direct short
to ground, high current draw, improper wiring, incorrect fuse
or breaker size and/or type. This needs to be evaluated by a
service center or certified electrician
7. Check and reset if necessary. If the overload trips after the
initial reset, refer to the section below "Reset trips on starter"
1. Any wiring other than what is stated in the manual could cause
a malfunction (see Wiring Section)
2. Make sure voltage is correct with the motor wiring (see Wiring
Section)
3. The entire electrical system should be checked by a certified
electrician. The incoming wires and the compressor electrical
connections should be checked. Loose connections will cause
malfunctions
1. Check voltage, wire size, etc. This problem needs to be
evaluated and corrected (see Wiring Section)
2. Make sure voltage is correct with the motor wiring (see Wiring
Section)
3. Check to make sure wire size is rated for the current of the
compressor. Check that wire size is rated for the current of the
compressor. State and local codes vary widely and need to be
checked before installation
1. Source electric to the compressor is either the incorrect
voltage, insufficient wire size to carry the load, the fuse box or
breaker box is not sufficient to carry the load requirements to
the compressor
2. The entire electrical system should be checked by a certified
electrician. The incoming wires and the compressor electrical
connections should be checked. Loose connections will cause
malfunctions
1. Make sure the drain valve at the bottom of the tank is closed
2. Check the entire system for leaks, including the compressor
unit and any piping attached to the compressor
3. Make sure that the air intake of the compressor is not blocked
in any way
