    Why does my RIDGID Air Compressor run continuously?
    • L
      Lisa MooreSep 10, 2025
      If your RIDGID Air Compressor runs continuously, it could be due to a defective pressure switch, which would need to be replaced. Alternatively, there might be excessive air usage, meaning you need to decrease air usage or the compressor isn't large enough for your requirements.

      If the air output of your RIDGID Air Compressor is lower than normal, several factors could be responsible. Loose mounting bolts should be repaired by an authorized service representative. Broken inlet valves may be the cause. A dirty intake filter should be cleaned or replaced, and all connections should be tightened.

    Why does the fuse blow or circuit breaker trip repeatedly on my RIDGID OF45175A?
    • Q

      If the fuses blow or the circuit breaker trips repeatedly on your RIDGID Air Compressor, it could be due to several reasons: 1. The fuse might be the incorrect size, or the circuit could be overloaded. Check for the proper fuse and use a time-delay fuse. Try disconnecting other electrical appliances from the circuit or operate the compressor on its own branch circuit. 2. The unit may be plugged into an extension cord; remove it. 3. A defective check valve or unloader could be the culprit; consider replacing or repairing these components.

      If the motor of your RIDGID Air Compressor hums but cannot run or runs slowly, consider the following potential causes: * Low voltage could be the issue. Check the voltage with a voltmeter. * The unit may be plugged into an extension cord, which should be removed. * There might be a shorted or open motor winding, requiring motor replacement. * A defective check valve or unloader could also be the cause, needing replacement or repair.
