  If the motor of your Kobalt Air Compressor won't run, here's what you can do: 1. If the tank pressure is too high, the motor will start automatically when the pressure drops. 2. Replace any blown fuses or reset tripped circuit breakers, ensuring you use the correct type and check for low voltage. Consider using a dedicated circuit. 3. Clean or replace the check valve if it's stuck open. 4. Ensure the extension cord has the correct gauge (18 AWG) and isn't excessively long (72 ft). 5. Turn off the compressor, unplug it, and allow the motor to cool down if the thermal overload protection has tripped. Plug it back in after cooling.

What to do if the regulated pressure gauge reading drops when using the air accessory on my Kobalt 3300243 Air Compressor?

  When using an air accessory with your Kobalt Air Compressor, it's normal for the regulated pressure gauge reading to drop somewhat. However, if the pressure drops too low, adjust the regulator while the accessory is in use. Also, ensure that your compressor is large enough for the accessory's air requirements; if not, a larger compressor may be needed.

Why is there low pressure in my Kobalt 3300243 Air Compressor, not enough air, or why doesn't it stop?

  Kelly ScottAug 15, 2025
  If your Kobalt Air Compressor has low pressure, isn't providing enough air, or won't stop, here's what to check: * Ensure the tank drain valve is closed. * Inspect for leaks using soapy water, and tighten or reseal with thread seal tape, being careful not to overtighten. * Reduce air usage if it's excessive. * Verify the compressor size meets your accessory requirements. If not, consider a larger compressor. * Check the air hose for holes and replace if needed. * If the tank, seals, or valves are leaking or the piston is worn, replacement of the compressor is necessary.

Why is air leaking from the regulator of my Kobalt 3300243 Air Compressor, or why doesn't the regulator regulate air pressure?

  If air is leaking from the regulator of your Kobalt Air Compressor, or if the regulator isn't controlling air pressure, the internal parts of the regulator may be dirty or damaged. Replace the regulator or its internal parts to resolve this issue.

Why does the pressure relief valve open on my Kobalt 3300243?

  The pressure relief valve on your Kobalt Air Compressor may open if the tank pressure exceeds its normal rating or if the pressure switch is stuck. In either of these cases, replace the compressor.
