  If your RIDGID Air Compressor won't run, there are several potential causes: * It might be plugged into an extension cord. If so, remove the extension cord. * There may be no electrical power. Ensure it's plugged in and check the fuse/breaker or motor overload. * A blown fuse could be the issue. Replace the blown fuse. * The breaker might be open. Reset it, and determine why the problem occurred. * The thermal overload could be open. The motor will restart when cool. * The pressure switch might be faulty. Replace it.

  If the fuses blow or the circuit breaker trips repeatedly on your RIDGID Air Compressor, it could be due to several reasons: * The fuse might be the incorrect size, or the circuit is overloaded. Check for the proper fuse and use a time-delay fuse. Disconnect other electrical appliances from the circuit or operate the compressor on its own branch circuit. * The unit might be plugged into an extension cord. Remove the extension cord. * The check valve or unloader might be defective. Replace or repair it.
