Symptoms We Resolve

COMMON DOL STARTER FAULTS

  • CONTACTOR COIL FAILURE

    A failed coil will prevent the contactor pulling in even when a valid start signal is present.
  • BURNT MAIN CONTACTS

    Repeated motor starting can pit and burn contact surfaces, causing voltage drop and overheating.
  • OVERLOAD TRIPS

    Motor loading, electrical faults, incorrect settings, or motor deterioration can cause repeated overload operation.
  • START/STOP CONTROL FAULTS

    Damaged pushbuttons, relays, interlocks, or wiring can interrupt the control circuit.
  • AUXILIARY CONTACT FAILURE

    Holding circuits and electrical interlocks rely on auxiliary contacts that can wear or fail.
  • PHASE LOSS

    Blown protection, loose terminals, or supply faults can leave the motor running or attempting to start on fewer than three phases.
