  Your Ryobi air compressor might not be running due to several reasons. First, ensure the unit is properly plugged in and check for the correct use of the extension cord. Also, inspect the fuse or breaker, and replace any blown fuses. If the shop/house breaker is open, reset it, and determine why it tripped. If the current limiting protector is open, reset the motor overload after the motor has cooled. Another potential cause is a bad pressure switch, which would need replacement. Finally, the compressor will only turn on when the tank pressure drops to the cut-in pressure; if the tank is full, it will remain off.

  If the motor of your Ryobi Air Compressor hums but doesn't run or runs slowly, it could be due to low voltage. Use a voltmeter to check the voltage. Also, check the extension cord for the correct gauge wire and length. If these steps don't resolve the issue, the motor might have a shorted or open winding, or the check valve or unloader might be defective, requiring a visit to a service center.

  If the current limiting protector in your Ryobi Air Compressor is cutting out repeatedly, the issue might stem from low voltage. Use a voltmeter to check it. Another potential cause is inadequate ventilation or a high room temperature; try moving the compressor to a well-ventilated area. Lastly, ensure that you are using the correct gauge wire and cord length for the extension cord.

  If the air tank pressure drops when your Ryobi Air Compressor shuts off, check all connections (fittings, tubing, etc.) for leaks using a soap and water solution, and tighten any loose connections. Also, make sure the drain valve is tightened. If the issue persists, the check valve might be leaking.
