Common GE Inverter Problems We Repair

GE inverters, while robust, can encounter various issues that require professional attention. These problems can range from minor malfunctions to critical failures that halt operations. At Roc Industrial LLC, we have extensive experience diagnosing and repairing common GE inverter faults.

  • DC Bus Overvoltage/Undervoltage: This is a frequent issue, often caused by regenerative energy or power supply problems.

  • DC Bus Fault: Indicates a short circuit or insulation breakdown in the DC bus circuit.

  • Overcurrent Fault: Triggered by excessive current draw, potentially damaging the inverter's components.

  • Overtemperature Fault: Occurs when the inverter overheats due to inadequate cooling or excessive load.

  • Communication Errors: Disruptions in communication between the inverter and other devices in the system.

  • IGBT Failures: Insulated Gate Bipolar Transistors (IGBTs) are critical components that can fail due to voltage spikes or thermal stress.

  • Blown Fuses: Indicates an overcurrent condition or short circuit within the inverter.

  • Encoder Faults: Problems with the encoder feedback signal, affecting motor control accuracy.

  • Ground Faults: Leakage of current to ground, posing a safety hazard and indicating insulation issues.

  • Power Supply Failures: Malfunctions in the inverter's internal power supply, affecting overall operation.

  • Dead Inverter: The inverter fails to power on or respond to commands.

  • Output Voltage Imbalance: Uneven voltage distribution across the output phases.

  • Drive tripping: Inverter shuts down unexpectedly during operation.
