Why Kobalt LK20175 does not run?
- B
  barbertammyAug 16, 2025
  If your Kobalt Air Compressor isn't running, there could be several reasons. First, ensure it's properly plugged in and the power switch is in the ON position. Check the extension cord for proper use. Also, a fuse might have blown or a breaker tripped at the power supply, so replace the fuse or reset the breaker. If the thermal overload is open, unplug the compressor and wait for it to cool down. The motor should restart automatically. If the tank is full, the compressor will start when the pressure drops. If none of these solutions work, the pressure switch may be bad and require replacement.

Why air pressure drops when Kobalt LK20175 shuts off?

  Troy SmithAug 19, 2025
  If the air pressure drops in your Kobalt Air Compressor after it shuts off, check all connections (fittings, tubing, etc.) with soapy water for leaks, indicated by bubbles, and tighten any loose connections. Also, tighten the drain valve. If these steps don't solve the issue, the check valve may be leaking, requiring professional service.

Why Kobalt LK20175 Air Compressor motor hums but does not run?
- A
  Ana GoodmanAug 21, 2025
  If your Kobalt Air Compressor motor hums but doesn't run or runs slowly, the voltage from the power supply might be low; check it with a voltmeter. Also, ensure you're using the correct wire gauge and length for the extension cord. If these aren't the issue, the motor winding or the unloader/check valve may be defective, requiring a visit to a service center.

  If the thermal overload protector on your Kobalt Air Compressor cuts out repeatedly, check the voltage from the power supply with a voltmeter. Ensure the compressor is in a well-ventilated area to prevent overheating. Also, verify that you are using the correct gauge wire and cord length.

What to do if Kobalt LK20175 runs continuously?
- B
  Brittany MillerAug 28, 2025
  If your Kobalt Air Compressor runs continuously, first check that the tank drain valve is closed. If it is, the pressure switch might be defective, requiring a visit to a service center. Also, consider whether the usage is excessive; the compressor might not be large enough for the tool's air requirements, so reduce the tool run-time.

What to do if fuses blow repeatedly on Kobalt LK20175 Air Compressor?
- C
  crosbyzacharySep 6, 2025
  If the fuses blow or the circuit breaker trips repeatedly on your Kobalt Air Compressor, make sure the fuse or breaker at the power supply is the correct size and type. Use only time-delay fuses to avoid overloading the circuit. Try disconnecting other electrical appliances from the circuit or operate the compressor on its own branch circuit. Also, ensure you are using the correct wire gauge and length of extension cord. If the problem persists, the unloader or check valve might be defective, requiring service.

How to reduce moisture in Kobalt LK20175 discharge?
- J
  Jordan WoodardSep 9, 2025
  If there is excessive moisture in the air discharge from your Kobalt Air Compressor, it may be due to excessive water in the air tank; drain the tank to remove the water. High humidity can also cause this issue; move the compressor to an area with less humidity or use an air line filter to reduce moisture discharge.
