If the Pro Air 20 or Pro Air 60 compressor does not operate:
- Verify that the electrical outlet has power.
- Check whether the GFCI outlet has tripped and reset it if necessary.
- Confirm that the compressor is receiving the proper supply voltage.
- Inspect the power cord for visible damage.
- Disconnect the air tubing temporarily and check whether the compressor operates without excessive back pressure.
If the compressor receives proper power but still does not operate, internal service or replacement components may be required.
